Public Datasets for Data Visualization Projects
A typical data visualization project might be something along the lines of “I want to make an infographic about how income varies across the different states in the US.” There are a few considerations to keep in mind when looking for a good dataset for a data visualization project:
- It shouldn’t be messy, because you don’t want to spend a lot of time cleaning data.
- It should be nuanced and interesting enough to make charts about.
- Ideally, each column should be well-explained, so the visualization is accurate.
- The data set shouldn’t have too many rows or columns, so it’s easy to work with.
Good places to find good datasets for data visualization projects are news sites that release their data publicly. They typically clean the data for you and already have charts that you can replicate or improve.
FiveThirtyEight is an incredibly popular interactive news and sports site started by Nate Silver . They write interesting data-driven articles, like “Don’t blame a skills gap for lack of hiring in manufacturing” and “2016 NFL Predictions .”
FiveThirtyEight makes the datasets used in its articles available online on GitHub .

NASA is a publicly-funded government organization, and thus all of its data is public. It maintains websites where anyone can download its datasets related to earth science and datasets related to space . You can even sort by format on the earth science site to find all of the available CSV datasets, for example.
Public Datasets for Data Processing Projects
Sometimes you just want to work with a large dataset. The end result doesn’t matter as much as the process of reading in and analyzing the data. You might use tools like Spark or Hadoop to distribute the processing across multiple nodes. Things to keep in mind when looking for a good data processing dataset:
- The cleaner the data, the better — cleaning a large dataset can be very time consuming.
- The dataset should be interesting.
- There should be an interesting question that can be answered with the data.
Good places to find large public data sets are cloud-hosting providers like Amazon and Google . They have an incentive to host the data sets because they make you analyze them using their infrastructure (and pay them to use it).
4. AWS Public Data sets
Amazon makes large datasets available on its Amazon Web Services platform. You can download the data and work with it on your own computer or analyze the data in the cloud using EC2 and Hadoop via EMR . You can read more about how the program works here .
Amazon has a page that lists all of the datasets for you to browse. You’ll need an AWS account, although Amazon provides a free access tier for new accounts that will enable you to explore the data without being charged.

- All Images and Other Media from Wikipedia — all the images and other media files on Wikipedia.
- Full Site Dumps — of the content on Wikipedia, in various formats.
Public Datasets for Machine Learning Projects
When you’re working on a machine learning project, you want to be able to predict a column from the other columns in a dataset. In order to be able to do this, we need to make sure that:
- The dataset isn’t too messy — if it is, we’ll spend all of our time cleaning the data.
- There’s an interesting target column to make predictions for.
- The other variables have some explanatory power for the target column.
There are a few online repositories of datasets that are specifically for machine learning. These datasets are typically cleaned up beforehand, and allow for testing of algorithms very quickly.
Kaggle is a data science community that hosts machine learning competitions. There are a variety of externally-contributed, interesting datasets on the site. Kaggle has both live and historical competitions. You can download data for either, but you have to sign up for Kaggle and accept the terms of service for the competition.
You can download data from Kaggle by entering a competition . Each competition has its own associated dataset. There are also user-contributed datasets found in the new Kaggle Datasets offering.

Public Datasets for Data Cleaning Projects
When looking for a good dataset for a data cleaning project, you want:
- Be spread over multiple files.
- Have a lot of nuance, and many possible angles to take.
- Require a good amount of research to understand.
- Be as “real-world” as possible.
These types of datasets are typically found on aggregators of datasets. These aggregators tend to have datasets from multiple sources, without much curation. Too much curation gives us overly neat datasets that are hard to do extensive cleaning on.
data.world describes itself as ‘the social network for data people,’ but could be more correctly described as ‘GitHub for data.’ It’s a place where you can search for, copy, analyze, and download datasets. In addition, you can upload your data to data.world and use it to collaborate with others.
In a relatively short time it has become one of the ‘go to’ places to acquire data, with lots of user contributed datasets as well as fantastic datasets through data.world’s partnerships with various organizations, including a large amount of data from the US Federal Government.
One key differentiator of data.world is they have built tools to make working with data easier – you can write SQL queries within their interface to explore data and join multiple datasets. They also have SDK’s for R and Python to make it easier to acquire and work with data in your tool of choice (You might be interested in reading our tutorial on the data.world Python SDK .)

Data.gov is a relatively new site that’s part of a US effort towards open government. Data.gov makes it possible to download data from multiple US government agencies. Data can range from government budgets to school performance scores. Much of the data requires additional research, and it can sometimes be hard to figure out which dataset is the “correct” version. Anyone can download the data, although some datasets require additional hoops to be jumped through, like agreeing to licensing agreements.
You can browse the data sets on Data.gov directly, without registering. You can browse by topic area or search for a specific dataset.

- Enron Emails — a set of many emails from executives at Enron, a company that famously went bankrupt.
- Student Learning Factors — a set of factors that measure and influence student learning.
- News Articles — contains news article attributes and a target variable.
Bonus: Streaming data
It’s very common when you’re building a data science project to download a dataset and then process it. However, as online services generate more and more data, an increasing amount is generated in real-time, and not available in dataset form. Some examples of this include data on tweets from Twitter , and stock price data. There aren’t many good sources to acquire this kind of data, but we’ll list a few in case you want to try your hand at a streaming data project.
Twitter has a good streaming API, and makes it relatively straightforward to filter and stream tweets. You can get started here . There are tons of options here — you could figure out what states are the happiest, or which countries use the most complex language. We also recently wrote an article to get you started with the Twitter API here .
Get started with the Twitter API
GitHub has an API that allows you to access repository activity and code. You can get started with the API here . The options are endless — you could build a system to automatically score code quality, or figure out how code evolves over time in large projects.
Get started with the Github API
Wunderground has an API for weather forecasts that free up to 500 API calls per day. You could use these calls to build up a set of historical weather data, and make predictions about the weather tomorrow.

18. Global Health Observatory
The World Health Organization (WHO) maintains a large dataset on global health at the Global Health Observatory (GHO) . The dataset includes all the WHO data on the COVID-19 global pandemic. The GHO offers a diverse range of data on topics such as antimicrobial resistance, dementia, air pollution, and immunization.
You can find data on pretty much any health-related topic at the GHO, making it an extremely valuable free dataset resource for data scientists working in the health field.
View WHO’s datasets.
19. Pew Research Center
The Pew Research Center is well-known for political and social science research. In the interest of furthering research and public discourse, they make all of their datasets publicly downloadable for secondary analysis, after a set period of time elapses.
You can choose from datasets on US politics, journalism and media, internet and tech, science and society, religion and public life, amongst other topics.
20. National Climatic Data Center
Climate change is a hot topic at the moment, if you’ll pardon the pun. Data scientists who want to crunch the numbers on weather and climate can access large US datasets from the National Centers for Environmental Information (NCEI) .
Bonus: Personal Data
The internet is full of cool datasets you can work with. But for something truly unique, what about analyzing your own personal data?
Here are some popular sites that make it possible to download and work with data you’ve generated.
Amazon allows you to download your personal spending data, order history, and more. To access it, click this link (you’ll need to be logged in for it to work) or navigate to the Accounts and Lists button in the top right.
On the next page, look for the Ordering and Shopping Preferences section, and click on the link under that heading that says “Download order reports.”Here is a simple data project tutorial that you could do using your own Amazon data to analyze your spending habits.
Facebook also allows you to download your personal activity data. To access it, click this link (you’ll need to be logged in for it to work) and select the types of data you’d like to download.Here is an example of a simple data project you could build using your own personal Facebook data .
Netflix allows you to request your own data for download , although it will make you jump through a few hoops, and will warn you that the process of collating your data may take 30 days. As of the last time we checked, the data they allow you to download is fairly limited, but it could still be suitable for some types of projects and analysis.
Extra Bonus: Powerful Dataset Search Tool
24. google dataset search.
OK, so this isn’t strictly a dataset – rather a search tool to find relevant datasets. As you already know, Google is a data powerhouse, so it makes sense that their search tool knocks the socks off of other ways to find specific datasets.
All you need to do is head over to Google Dataset Search and type a keyword or phrase related to the dataset you’re looking for in the search bar. The results will list all the datasets indexed on Google for that particular search term. The datasets are generally from high-quality sources, of which some are free and others available for a fee or subscription.
In this post, we covered good places to find datasets for any type of data science project. We hope that you find something interesting that you want to sink your teeth into!

Data science capstone ideas (and how to get started)
Capstones are standalone projects meant to integrate, synthesize, and demonstrate all your data science knowledge in a multi-faceted way. Capstone projects show your readiness for using data science in real life, and are ideally something you can add to your resume, show to employers, or even use to start a career.
I find data science capstone ideas are like puppies: you want all of them, but can only keep one. Below is a list of some of my ideas and starting points.
Idea #1: Nutritional analysis from Instacart orders
In 2017 Instacart released a dataset of over 3 million grocery orders from over 200,000 users as a Kaggle competition . With a dataset this juicy, immediately a few ideas come time to mind:
- Predict what products users will order again (this was the goal of the Kaggle challenge).
- Build a model to stock the store so there are never any product shortages, but no wasted space or money in ordering.
- Predict a user’s healthiness from order content.
- Make a recommender system for healthier order alternatives.
The first and second are doable with the data you already have, which is nice.
The third was my personal choice, using the USDA food composition database to look up products and create a nutritional breakdown (by the way, they have an API ). But it also introduced a lot of hurdles:
- Users don’t eat everything they order (e.g. cat food, soap, toilet paper). This would require a lot of cleaning and munging.
- Users don’t order just for themselves (e.g. companies, birthday parties, families).
- Users order on different timelines (e.g. once per week, once every two weeks, once a month).
- Items such as deli food may not have entries in the USDA database.
The fourth would also utilize the USDA database, but would not require any user-specific information or messing about with time-series.
I dea #2: Predicting solar output from satellite imaging/historical weather
One of the big issues with mainstream adoption of solar power is unlike other energy sources (hydroelectric, oil, nuclear), you can’t control how long the sun shines for. Overestimating this amount means losses for producers and investors, and downtime for users. Underestimating means a lower chance of adoption in upfront decision-making. Sounds like a job for… machine learning!
Many datasets can be found at NREL , however they are in different years and different locations with limits on how much you can download at once. They have an API , which is useful.
SolarAnywhere has an academic license, allowing you to look up any location (but only for the year 2013). They too have an API .
Also, the NREL NSRDB data viewer .
There are three immediate approaches I can think of:
- Using previous solar output to predict current solar output (time-series or RNN).
- Using weather datasets
- Using satellite imaging datasets
There are a lot of academic papers on this last subject ( a quick Google Scholar search returns about 30,000 results ), but not a lot of publicly available satellite time-series datasets.
Idea #3: Fake news detection
This is a hot one. Without going into full rant-mode, fake news is obviously deleterious for democracy and individual mental stability.
So how to accurately identify what’s fake and what’s true? Here are a few leads on this as a data science problem:
1. Fake News Challenge
This is the best-formatted challenge around this topic, with organizers, advisors, and volunteers from the academic, ML, and fact-checking communities. Includes GitHub repos of winning submissions. Check out the competition page on Codalab.
2. Snopes Junk News
A starting point for well-verified fake news stories vs. actual events.
3. Getting Real About Fake News — Kaggle Dataset
A collection of nearly 13,000 items from 244 websites tagged “BS” from the BS Detector chrome extension. The BS Detector is powered by Open Sources , a project that classifies biased and fake websites.
Where To Get More Ideas
Never stop searching! Here are some ways to get more leads, either in the form of project ideas or datasets to use.

9 Project Ideas for Your Data Analytics Portfolio
Finding projects for your data analytics portfolio can be tricky, especially when you’re new to the field. You might also think that your data projects need to be especially complex or showy, but that’s not the case. The most important thing is to demonstrate your skills, ideally using a dataset that interests you. And the good news? Data is everywhere—you just need to know where to find it and what to do with it.
In this post, we’ll highlight the key elements that your data analytics portfolio should demonstrate. We’ll then share nine project ideas that will help you build your portfolio from scratch, focusing on three key areas: Data scraping , exploratory analysis , and data visualization .
- What should you include in your data analytics portfolio?
Data scraping project ideas
Exploratory data analysis project ideas, data visualization project ideas.
- What’s next?
Ready to get inspired? Let’s go!
1. What should you include in your data analytics portfolio?
Data analytics is all about finding insights that inform decision-making. But that’s just the end goal. As any experienced data analyst will tell you, the insights we see as consumers are the result of a great deal of work. In fact, about 80% of all data analytics tasks involve preparing data for analysis. This makes sense when you think about it—after all, our insights are only as good as the quality of our data.
Yes, your portfolio needs to show that you can carry out different types of data analysis . But it also needs to show that you can collect data, clean it, and report your findings in a clear, visual manner. As your skills improve, your portfolio will grow in complexity. As a beginner though, you’ll need to show that you can:
- Scrape the web for data
- Carry out exploratory analyses
- Clean untidy datasets
- Communicate your results using visualizations
If you’re inexperienced, it can help to present each item as a mini-project of its own. This makes life easier since you can learn the individual skills in a controlled way. With that in mind, we’ll keep it nice and simple with some basic ideas, and a few tools you might want to explore to help you along the way.
2. Data scraping project ideas for your portfolio
What is data scraping.
Data scraping is the first step in any data analytics project. It involves pulling data (usually from the web) and compiling it into a usable format. While there’s no shortage of great data repositories available online, scraping and cleaning data yourself is a great way to show off your skills.
The process of web scraping can be automated using tools like Parsehub , ScraperAPI , or Octoparse (for non-coders) or by using libraries like Beautiful Soup or Scrapy (for developers). Whichever tool you use, the important thing is to show that you understand how it works and can apply it effectively.
Before scraping a website, be sure that you have permission to do so. If you’re not certain, you can always search for a dataset on a repository site like Kaggle . If it exists there, it’s a good bet you can go straight to the source and scrape it yourself. Bear in mind though—data scraping can be challenging if you’re mining complex, dynamic websites. We recommend starting with something easy—a mostly-static site. Here are some ideas to get you started.
The Internet Movie Database
A good beginner’s project is to extract data from IMDb. You can collect details about popular TV shows, movie reviews and trivia, the heights and weights of various actors, and so on. Data on IMDb is stored in a consistent format across all its pages, making the task a lot easier. There’s also a lot of potential here for further analysis.
Many beginners like scraping data from job portals since they often contain standard data types. You can also find lots of online tutorials explaining how to proceed. To keep it interesting, why not focus on your local area? Collect job titles, companies, salaries, locations, required skills, and so on. This offers great potential for later visualization, such as graphing skillsets against salaries.
Another popular one is to scrape product and pricing data from e-commerce sites. For instance, extract product information about Bluetooth speakers on Amazon, or collect reviews and prices on various tablets and laptops. Once again, this is relatively straightforward to do, and it is scalable. This means you can start with a product that has a small number of reviews, and then upscale once you’re comfortable using the algorithms.
For something a bit less conventional, another option is to scrape a site like Reddit. You could search for particular keywords, upvotes, user data, and more. Reddit is a very static website, making the task nice and straightforward. Later, you can carry out interesting exploratory analyses, for instance, to see if there are any correlations between popular posts and particular keywords. Which brings us to our next section.
3. Exploratory data analysis project ideas
What is exploratory data analysis.
The next step in any data analyst’s skillset is the ability to carry out an exploratory data analysis (EDA). An EDA looks at the structure of data, allowing you to determine their patterns and characteristics. They also help you to clean your data. You can extract important variables, detect outliers and anomalies, and generally test your underlying assumptions.
While this process is one of the most time-consuming tasks for a data analyst, it can also be one of the most rewarding. Later modeling focuses on generating answers to specific questions. An EDA, meanwhile, helps you do one of the most exciting bits—generating those questions in the first place.
Languages like R and Python are often used to carry out these tasks. They have many pre-existing algorithms that you can use to carry out the work for you . The real skill lies in presenting your project and its results. How you decide to do this is up to you, but one popular method is to use an interactive documentation tool like Jupyter Notebook . This lets you capture elements of code, along with explanatory text and visualizations, all in one place. Here are some ideas for your portfolio.
Global suicide rates
This global suicide rates dataset covers suicide rates in various countries, with additional data including year, gender, age, population, GDP, and more. When carrying out your EDA, ask yourself: What patterns can you see? Are suicides rates climbing or falling in various countries? What variables (such as gender or age) can you find that might correlate to suicide rates?
World Happiness Report
On the other end of the scale, the World Happiness Report tracks six factors to measure happiness across the world’s citizens: life expectancy, economics, social support, absence of corruption, freedom, and generosity. So, which country is the happiest? Which continent? Which factor appears to have the greatest (or smallest) impact on a nation’s happiness? Overall, is happiness increasing or decreasing?
Aside from the two ideas above, you could also use your own datasets . After all, if you’ve already scraped your own data, why not use them? For instance, if you scraped a job portal, which locations or regions offer the best-paid jobs? Which offer the least well-paid ones? Why might that be? Equally, with e-commerce data, you could look at which prices and products offer the best value for money.
Ultimately, whichever dataset you’re using, it should grab your attention. If the data are too complex or don’t interest you, you’re likely to run out of steam before you get very far. Keep in mind what further probing you can do to spot interesting trends or patterns, and to extract the insights you need.
We’ve compiled a list of ten great places to find free datasets for your next project here .
4. Data visualization project ideas
What is data visualization.
Scraping, tidying, and analyzing data is one thing. Communicating your findings is another. Our brains don’t like looking at numbers and figures, but they love visuals. This is where the ability to create effective data visualizations comes in. Good visualizations—whether static or interactive—make a great addition to any data analytics portfolio. Showing that you can create visualizations that are both effective and visually appealing will go a long way towards impressing a potential employer.
Check out this video with Dr. Humera, where she explains how visualization helps tell a story with data.
Some free visualization tools include Google Charts , Canva Graph Maker (free), and Tableau Public . Meanwhile, if you want to show off your coding abilities, use a Python library such as Seaborn , or flex your R skills with Shiny . Needless to say, there are many tools available to help you. The one you choose depends on what you’re looking to achieve. Here’s a bit of inspiration…
Topical subject matter looks great on any portfolio, and the pandemic is nothing if not topical! What’s more, sites like Kaggle already have thousands of Covid-19 data sets available . How can you represent the data? Could you use a global heatmap to show where cases have spiked, versus where there are very few? Perhaps you could create two overlapping bar charts to show known infections versus predicted infections. Here’s a handy tutorial to help you visualize Covid-19 data using R, Shiny, and Plotly .
Most followed on Instagram
Whether you’re interested in social media, or celebrity and brand culture, this dataset of the most-followed people on Instagram has great potential for visualization. You could create an interactive bar chart that tracks changes in the most followed accounts over time. Or you could explore whether brand or celebrity accounts are more effective at influencer marketing. Otherwise, why not find another social media dataset to create a visualization? For instance, this map of the USA by data scientist Greg Rafferty nicely highlights the geographical source of trending topics on Instagram.
Another topic that lends itself well to visualization is transport data. Here’s a great project by Chen Chen on github , using Python to visualize the top tourist destinations worldwide, and the correlation between inbound/outbound tourists with gross domestic product (GDP).
5. What’s next?
In this post, we’ve explored which skills every beginner needs to demonstrate in their data analytics portfolio. Regardless of the dataset you’re using, you should be able to demonstrate the following abilities:
- Web scraping —using tools like Parsehub, Beautiful Soup, or Scrapy to extract data from websites (remember: static ones are easier!)
- Exploratory data analysis and data cleaning —manipulating data with tools like R and Python, before drawing some initial insights.
- Data visualization —utilizing tools like Tableau, Shiny, or Plotly to create crisp, compelling dashboards, and visualizations.
Once you’ve mastered the basics, you can start getting more ambitious with your data analytics projects. For example, why not introduce some machine learning projects, like sentiment analysis or predictive analysis? The key thing is to start simple and to remember that a good data analytics portfolio needn’t be flashy, just competent.
To further develop your skills, there are loads of online courses designed to set you on the right track. To start with, why not try our free, five-day data analytics short course ?

26 Data Analytics Project Ideas and Datasets (2022)
Data analytics projects help you build your portfolio and land interviews. However, it’s not enough to just do an interesting analytics project. You also have to market your project to ensure it gets found.
The first step in starting any data analytics project is to come up with an interesting problem to investigate. Then, you need to find a dataset to analyze the problem. Some of the best categories for data analytics project ideas include:
- Python Analytics Projects - Python allows you to scrape interesting data, as well as perform analysis with pandas dataframes and SciPy libraries.
- Housing Analytics Projects - Housing data is readily available, or you can create your own dataset, and there are a variety of interesting analyses you can perform.
- Sports and NBA Analytics Projects - Sports data can be easily scraped, and using player and game stats, you can analyze strategies and performance.
- Data Visualization Projects - Visualizations allow you to create graphs, charts, etc, to tell a story about the data.
- Beginner Analytics Projects - For early-career data analysts, beginner projects help you practice new skills.
A data analytics portfolio is a powerful tool for landing an interview. But how can you build one effectively?
Start with a data analytics project and build your portfolio around it. A data analytics project involves taking a dataset and analyzing it in a specific way to showcase results. Not only do they help you build your portfolio, but analytics projects also help you:
- Learn new tools and techniques
- Work with complex datasets
- Practice packaging your work and results
- Prep for a case study and take-home interviews
- Give you inbound interviews from hiring managers that have read your blog post!
Python Data Analytics Projects
Python is a powerful tool for data analysis projects. Whether you’re web scraping data - on sites like the New York Times and Craigslist- or you’re conducting Exploratory Data Analysis (EDA) on Uber trips, here are three Python data analytics project ideas to try:
1. Enigma Transforming CSV file Take-Home
This take-home challenge - which requires 1-2.5 hours to complete - is a Python script writing task. You’re asked to write a script to transform input CSV data to desired output CSV data. A take-home like this is good practice for the type of Python take-homes that are asked of data analysts, data scientists, and data engineers.
As you work through this practice challenge, focus specifically on the grading criteria, which include:
- How well do you solve the problems
- The logic and approach you take to solving them
- Your ability to produce, document, and comment on code
- Ultimately, the ability to write clear and clean scripts for data preparation.

What are the areas where big data analytics is used.
Before jumping into the list of big data topics t hat you can try out as a beginner, you need to understand the areas of application of the subject. This will help you invent your own topics for data processing projects once you complete a few from the list. Hence, let’s see what are the areas where big data analytics is used the most. This will help you navigate how to identify issues in certain industries and how they can be resolved with the help of big data as big data research projects.
- Banking and Safety:
The banking industry often deals with cases of card fraud, security fraud, ticks and such other issues that greatly hamper their functioning as well as market reputation. Hence to tackle that, the securities exchange commission aka SEC takes the help of big data and monitors the financial market activity.
This has further helped them manage a safer environment for highly valuable customers like retail traders, hedge funds, big banks and other eminent individuals in the financial market. Big data has helped this industry in the cases like anti-money laundering, fraud mitigation, demand enterprise risk management and other cases of risk analytics.
- Media and Entertainment industry
It is needless to say that the media and entertainment industry heavily depends on the verdict of the consumers and this is why they are always required to put up their best game. For that, they require to understand the current trends and demands of the public, which is also something that changes rapidly these days.
To get an in-depth understanding of consumer behaviour and their needs, the media and entertainment industry collects, analyses and utilises customer insights. They leverage mobile and social media content to understand the patterns at a real-time speed.
The industry leverages Big data to run detailed sentiment analysis to pitch the perfect content to the users. Some of the biggest names in the entertainment industry such as Spotify and Amazon Prime are known for using big data to provide accurate content recommendations to their users, which helps them improve their customer satisfaction and, therefore, increases customer retention.
- Healthcare Industry
Even though the healthcare industry generates huge volumes of data on a daily basis which can be ustilised in many ways to improve the healthcare industry, it fails to utilise it completely due to issues of usability of it. Yet there is a significant number of areas where the healthcare industry is continuously utilising Big Data.
The main area where the healthcare industry is actively leveraging big data is to improve hospital administration so that patients can revoke best-in-class clinical support. Apart from that, Big Data is also used in fighting lethal diseases like cancer. Big Data has also helped the industry to save itself from potential frauds and committing usual man-made errors like providing the wrong dosage, medicine etc.
Similar to the society that we live in, the education system is also evolving. Especially after the pandemic hit hard, the change became even more rapid. With the introduction of remote learning, the education system transformed drastically, and so did its problems.
On that note, Big Data significantly came in handy, as it helped educational institutions to get the insights that can be used to take the right decisions suitable for the circumstances. Big Data helped educators to understand the importance of creating a unique and customised curriculum to fight issues like students not being able to retain attention.
It not only helped improve the educational system but to identify the student’s strengths and channeled them right.
- Government and Public Services
Likewise the field of government and public services itself, the applications of Big Data by them are also extensive and diverse. Government leverages big data mostly in areas like financial market analysis, fraud detection, energy resource exploration, environment protection, public-health-related research and so forth.
The Food and Drug Administration (FDA) actively uses Big Data to study food-related illnesses and disease patterns.
- Retail and Wholesale Industry
In spite of having tons of data available online in form of reviews, customer loyalty cards, RFID etc. the retail and wholesale industry is still lacking in making complete use of it. These insights hold great potential to change the game of customer experience and customer loyalty.
Especially after the emergence of e-commerce, big data is used by companies to create custom recommendations based on their previous purchasing behaviour or even from their search history.
In the case of brick-and-mortar stores as well, big data is used for monitoring store-level demand in real-time so that it can be ensured that the best-selling items remain in stock. Along with that, in the case of this industry, data is also helpful in improving the entire value chain to increase profits.
- Manufacturing and Resources Industry
The demand for resources of every kind and manufactured product is only increasing with time which is making it difficult for industries to cope. However, there are large volumes of data from these industries that are untapped and hold the potential to make both industries more efficient, profitable and manageable.
By integrating large volumes of geospatial and geographical data available online, better predictive analysis can be done to find the best areas for natural resource explorations. Similarly, in the case of the manufacturing industry, Big Data can help solve several issues regarding the supply chain and provide companies with a competitive edge.
- Insurance Industry
The insurance industry is anticipated to be the highest profit-making industry but its vast and diverse customer base makes it difficult for it to incorporate state-of-the-art requirements like personalized services, personalised prices and targeted services. To tackle these prime challenges Big Data plays a huge part.
Big data helps this industry to gain customer insights that further help in curating simple and transparent products that match the recruitment of the customers. Along with that, big data also helps the industry analyse and predict customer behaviours and results in the best decision-making for insurance companies. Apart from predictive analytics, big data is also utilised in fraud detection.
What problems you might face in doing Big Data Projects
Big data is present in numerous industries. So you’ll find a wide variety of big data project topics to work on too.
Apart from the wide variety of project ideas, there are a bunch of challenges a big data analyst faces while working on such projects.
They are the following:
Limited Monitoring Solutions
You can face problems while monitoring real-time environments because there aren’t many solutions available for this purpose.
That’s why you should be familiar with the technologies you’ll need to use in big data analysis before you begin working on a project.
A common problem among data analysis is of output latency during data virtualization. Most of these tools require high-level performance, which leads to these latency problems.
Due to the latency in output generation, timing issues arise with the virtualization of data.
The requirement of High-level Scripting
When working on big data analytics projects, you might encounter tools or problems which require higher-level scripting than you’re familiar with.
In that case, you should try to learn more about the problem and ask others about the same.
Data Privacy and Security
While working on the data available to you, you have to ensure that all the data remains secure and private.
Leakage of data can wreak havoc to your project as well as your work. Sometimes users leak data too, so you have to keep that in mind.
Knowledge Read: Big data jobs & Career planning
Unavailability of Tools
You can’t do end-to-end testing with just one tool. You should figure out which tools you will need to use to complete a specific project.
When you don’t have the right tool at a specific device, it can waste a lot of time and cause a lot of frustration.
That is why you should have the required tools before you start the project.
Check out big data certifications at upGrad
Too Big Datasets
You can come across a dataset which is too big for you to handle. Or, you might need to verify more data to complete the project as well.
Make sure that you update your data regularly to solve this problem. It’s also possible that your data has duplicates, so you should remove them, as well.
While working on big data projects, keep in mind the following points to solve these challenges:
- Use the right combination of hardware as well as software tools to make sure your work doesn’t get hampered later on due to the lack of the same.
- Check your data thoroughly and get rid of any duplicates.
- Follow Machine Learning approaches for better efficiency and results.
- What are the technologies you’ll need to use in Big Data Analytics Projects:
We recommend the following technologies for beginner-level big data projects:
- Open-source databases
- C++, Python
- Cloud solutions (such as Azure and AWS)
- R (programming language)
Each of these technologies will help you with a different sector. For example, you will need to use cloud solutions for data storage and access.
On the other hand, you will need to use R for using data science tools . These are all the problems you need to face and fix when you work on big data project ideas.
If you are not familiar with any of the technologies we mentioned above, you should learn about the same before working on a project. The more big data project ideas you try, the more experience you gain.
Otherwise, you’d be prone to making a lot of mistakes which you could’ve easily avoided.
So, here are a few Big Data Project ideas which beginners can work on:

Big data project ideas: advanced level, 4. big data for cybersecurity.
This project will investigate the long-term and time-invariant dependence relationships in large volumes of data. The main aim of this Big Data project is to combat real-world cybersecurity problems by exploiting vulnerability disclosure trends with complex multivariate time series data. This cybersecurity project seeks to establish an innovative and robust statistical framework to help you gain an in-depth understanding of the disclosure dynamics and their intriguing dependence structures.
5. Health status prediction
This is one of the interesting big data project ideas. This Big Data project is designed to predict the health status based on massive datasets. It will involve the creation of a machine learning model that can accurately classify users according to their health attributes to qualify them as having or not having heart diseases. Decision trees are the best machine learning method for classification, and hence, it is the ideal prediction tool for this project. The feature selection approach will help enhance the classification accuracy of the ML model.
6. Anomaly detection in cloud servers
In this project, an anomaly detection approach will be implemented for streaming large datasets. The proposed project will detect anomalies in cloud servers by leveraging two core algorithms – state summarization and novel nested-arc hidden semi-Markov model (NAHSMM). While state summarization will extract usage behaviour reflective states from raw sequences, NAHSMM will create an anomaly detection algorithm with a forensic module to obtain the normal behaviour threshold in the training phase.
7. Recruitment for Big Data job profiles
Recruitment is a challenging job responsibility of the HR department of any company. Here, we’ll create a Big Data project that can analyze vast amounts of data gathered from real-world job posts published online. The project involves three steps:
- Identify four Big Data job families in the given dataset.
- Identify nine homogeneous groups of Big Data skills that are highly valued by companies.
- Characterize each Big Data job family according to the level of competence required for each Big Data skill set.
The goal of this project is to help the HR department find better recruitments for Big Data job roles.
8. Malicious user detection in Big Data collection
This is one of the trending deep learning project ideas. When talking about Big Data collections, the trustworthiness (reliability) of users is of supreme importance. In this project, we will calculate the reliability factor of users in a given Big Data collection. To achieve this, the project will divide the trustworthiness into familiarity and similarity trustworthiness. Furthermore, it will divide all the participants into small groups according to the similarity trustworthiness factor and then calculate the trustworthiness of each group separately to reduce the computational complexity. This grouping strategy allows the project to represent the trust level of a particular group as a whole.
9. Tourist behaviour analysis
This is one of the excellent big data project ideas. This Big Data project is designed to analyze the tourist behaviour to identify tourists’ interests and most visited locations and accordingly, predict future tourism demands. The project involves four steps:
- Textual metadata processing to extract a list of interest candidates from geotagged pictures.
- Geographical data clustering to identify popular tourist locations for each of the identified tourist interests.
- Representative photo identification for each tourist interest.
- Time series modelling to construct a time series data by counting the number of tourists on a monthly basis.
10. Credit Scoring
This project seeks to explore the value of Big Data for credit scoring. The primary idea behind this project is to investigate the performance of both statistical and economic models. To do so, it will use a unique combination of datasets that contains call-detail records along with the credit and debit account information of customers for creating appropriate scorecards for credit card applicants. This will help to predict the creditworthiness of credit card applicants.
11. Electricity price forecasting
This is one of the interesting big data project ideas. This project is explicitly designed to forecast electricity prices by leveraging Big Data sets. The model exploits the SVM classifier to predict the electricity price. However, during the training phase in SVM classification, the model will include even the irrelevant and redundant features which reduce its forecasting accuracy. To address this problem, we will use two methods – Grey Correlation Analysis (GCA) and Principle Component Analysis. These methods help select important features while eliminating all the unnecessary elements, thereby improving the classification accuracy of the model.
BusBeat is an early event detection system that utilizes GPS trajectories of periodic-cars travelling routinely in an urban area. This project proposes data interpolation and the network-based event detection techniques to implement early event detection with GPS trajectory data successfully. The data interpolation technique helps to recover missing values in the GPS data using the primary feature of the periodic-cars, and the network analysis estimates an event venue location.
Yandex.Traffic was born when Yandex decided to use its advanced data analysis skills to develop an app that can analyze information collected from multiple sources and display a real-time map of traffic conditions in a city.
After collecting large volumes of data from disparate sources, Yandex.Traffic analyses the data to map accurate results on a particular city’s map via Yandex.Maps, Yandex’s web-based mapping service. Not just that, Yandex.Traffic can also calculate the average level of congestion on a scale of 0 to 10 for large cities with serious traffic jam issues. Yandex.Traffic sources information directly from those who create traffic to paint an accurate picture of traffic congestion in a city, thereby allowing drivers to help one another.

How can one create and validate models for their projects?
To create a model, one needs to find a suitable dataset. Initially, data cleaning has to be done. This includes filling missing values, removing outliers, etc. Then, one needs to divide the dataset into two parts: the Training and the Testing dataset. The ratio of training to testing is preferably 80:20. Algorithms like Decision tree, Support Vector Machine (SVM), Linear and Logistic Regression, K- Nearest Neighbours, etc., can be applied. After training, testing is done using the testing dataset. The model's prediction is compared to the actual values, and finally, the accuracy is computed.
What is the Decision tree algorithm?
A Decision tree is a classification algorithm. It is represented in the form of a tree. The partitioning attribute is selected using the information gain, gain ratio, and Gini index. At every node, there are two possibilities, i.e., it could belong to either of the classes. The attribute with the highest value of information gain, Gini index or gain ratio is chosen as the partitioning attribute. This process continues until we cannot split a node anymore. Sometimes, due to overfitting of the data, extensive branching might occur. In such cases, pre-pruning and post-pruning techniques are used to construct the tree optimally.

M.S. in Data Science students are required to complete a capstone project. Capstone projects challenge students to acquire and analyze data to solve real-world problems. Project teams consist of two to four students and a faculty advisor. Teams select their capstone project at the beginning of the year and work on the project over the course of two semesters.
Most projects are sponsored by an organization—academic, commercial, non-profit, and government—seeking valuable recommendations to address strategic and operational issues. Depending on the needs of the sponsor, teams may develop web-based applications that can support ongoing decision-making. The capstone project concludes with a paper and presentation.
- Synthesizing the concepts you have learned throughout the program in various courses (this requires that the question posed by the project be complex enough to require the application of appropriate analytical approaches learned in the program and that the available data be of sufficient size to qualify as ‘big’)
- Experience working with ‘raw’ data exposing you to the data pipeline process you are likely to encounter in the ‘real world’
- Demonstrating oral and written communication skills through a formal paper and presentation of project outcomes
- Acquisition of team building skills on a long-term, complex, data science project
Capstone projects have been sponsors by a variety of organizations and industries, including: Capital One, City of Charlottesville, Deloitte Consulting LLP, Metropolitan Museum of Art, MITRE Corporation, a multinational banking firm, The Public Library of Science, S&P Global Market Intelligence, UVA Brain Institute, UVA Center for Diabetes Technology, UVA Health System, U.S. Army Research Laboratory, Virginia Department of Health, Virginia Department of Motor Vehicles, Virginia Office of the Governor, Wikipedia, and more.
Sponsor a Capstone Project
View previous examples of capstone projects and check out answers to frequently asked questions.
What does the process look like?
- The School of Data Science periodically puts out a Call for Proposals . Prospective project sponsors submit official proposals, vetted by the SDS Associate Director for Research Development .
- Sponsors present their projects to students at “Pitch Day” near the start of the Fall term, where students have the opportunity to ask questions.
- Students individually rank their top project choices. An algorithm sorts students into capstone groups of approximately 3 to 4 students per group.
- Each group is assigned a faculty mentor, who will meet groups each week in a seminar-style format.
What is the seminar approach to mentoring capstones?
We utilize a seminar approach to managing capstones to provide faculty mentorship and streamlined logistics. This approach involves one mentor supervising three to four loosely related projects and meeting with these groups on a regular basis. Project teams often encounter similar roadblocks and issues so meeting together to share information and report on progress toward key milestones is highly beneficial.
Do all capstone projects have sponsors?
Not necessarily. Generally, each group works with a sponsor from outside the School of Data Science. Some sponsors are corporations, some are from nonprofit and governmental organizations, and some are from in other departments at UVA.
Why do we have to work in groups?
Because data science is a team sport!
All capstone projects are completed by group work. While this requires additional coordination , this collaborative component of the program reflects the way companies expect their employees to work. Building this skill is one of our core learning objectives for the program.
I didn’t get my first choice of capstone project from the algorithm matching. What can I do?
Remember that the point of the capstone projects isn’t the subject matter; it’s the data science. Professional data scientists may find themselves in positions in which they work on topics assigned to them, but they use methods they enjoy and still learn much through the process. That said, there are many ways to tackle a subject, and we are more than happy to work with you to find an approach to the work that most aligns with your interests.
Can I work on a project for my current employer?
Each spring, we put forward a public call for capstone projects. You are encouraged to share this call widely with your community, including your employer, non-profit organizations, or any entity that might have a big data problem that we can help solve. As a reminder, capstone projects are group projects so the project would require sufficient student interest after ‘pitch day’. In addition, you (the student) cannot serve as the project sponsor (someone else within your employer organization must serve in that capacity).
If my project doesn’t have a corporate sponsor, am I losing out on a career opportunity?
The capstone project will provide you with the opportunity to do relevant, high-quality work which can be included on a resume and discussed during job interviews. The project paper and your code on Github will provide more career opportunities than the sponsor of the project. Although it does happen from time to time, it is rare that capstones lead to a direct job offer with the capstone sponsor's company. Capstone projects are just one networking opportunity available to you in the program.
Capstone Project Reflections From Alumni
“Capstone projects are opportunities for you to deliver valuable, quantifiable results that you can use as a testimony of your long-term project success to the company you work for and other companies in future interviews.” — Gabriel Rushin, MSDS 2017, Procter & Gamble, Senior Machine Learning Engineer Manager
“For my capstone project, I worked to develop a clustering model to assess biogeographic ancestry, using DNA profiles. I felt like I was finally doing real-world data science and loved working with such an important organization as the Department of Defense.” — Colleen Callahan, Online MSDS 2021, Associate Research Analyst, CNA (Arlington, Virginia)
Capstone Project Reflections From Sponsors
“For us, the level of expertise, and special expertise, of the capstone students gives us ‘extra legs’ and an extra push to move a project forward. The team was asked to provide a replicable prototype air quality sensor that connected to the Cville Things Network, a free and community supported IoT network in Charlottesville. Their final product was a fantastic example that included clear circuit diagrams for replication by citizen scientists.” — Lucas Ames, Founder, Smart Cville
“Working with students on an exploratory project allowed us to focus on the data part of the problem rather than the business part, while testing with little risk. If our hypothesis falls flat, we gain valuable information; if it is validated or exceeded, we gain valuable information and are a few steps closer to a new product offering than when we started.” — Ellen Loeshelle, Senior Director of Product Management, Clarabridge

Top 15 Big Data Projects (With Source Code)
Introduction, big data project ideas, projects for beginners, intermediate big data projects, advanced projects, big data projects: why are they so important, frequently asked questions, additional resources.
Almost 6,500 million linked gadgets communicate data via the Internet nowadays. This figure will climb to 20,000 million by 2025. This “sea of data” is analyzed by big data to translate it into the information that is reshaping our world. Big data refers to massive data volumes – both organized and unstructured – that bombard enterprises daily. But it’s not simply the type or quantity of data that matters; it’s also what businesses do with it. Big data may be evaluated for insights that help people make better decisions and feel more confident about making key business decisions. Big data refers to vast, diversified amounts of data that are growing at an exponential rate. The volume of data, the velocity or speed with which it is created and collected, and the variety or scope of the data points covered (known as the “three v’s” of big data) are all factors to consider. Big data is frequently derived by data mining and is available in a variety of formats.
Unstructured and structured big data are two types of big data. For large data, the term structured data refers to data that has a set length and format. Numbers, dates, and strings, which are collections of words and numbers, are examples of organized data. Unstructured data is unorganized data that does not fit into a predetermined model or format. It includes information gleaned from social media sources that aid organizations in gathering information on customer demands.
Confused about your next job?
- Big data is a large amount of diversified information that is arriving in ever-increasing volumes and at ever-increasing speeds.
- Big data can be structured (typically numerical, readily formatted, to and saved) or unstructured (often non-numerical, difficult to format and store) (more free-form, less quantifiable).
- Big data analysis may benefit nearly every function in a company, but dealing with the clutter and noise can be difficult.
- Big data can be gathered willingly through personal devices and applications, through questionnaires, product purchases, and electronic check-ins, as well as publicly published remarks on social networks and websites.
- Big data is frequently kept in computer databases and examined with software intended to deal with huge, complicated data sets.
Just knowing the theory of big data isn’t going to get you very far. You’ll need to put what you’ve learned into practice. You may put your big data talents to the test by working on big data projects. Projects are an excellent opportunity to put your abilities to the test. They’re also great for your resume. In this article, we are going to discuss some great Big Data projects that you can work on to showcase your big data skills.
1. Traffic control using Big Data
Big Data initiatives that simulate and predict traffic in real-time have a wide range of applications and advantages. The field of real-time traffic simulation has been modeled successfully. However, anticipating route traffic has long been a challenge. This is because developing predictive models for real-time traffic prediction is a difficult endeavor that involves a lot of latency, large amounts of data, and ever-increasing expenses.
The following project is a Lambda Architecture application that monitors the traffic safety and congestion of each street in Chicago. It depicts current traffic collisions, red light, and speed camera infractions, as well as traffic patterns on 1,250 street segments within the city borders.
These datasets have been taken from the City of Chicago’s open data portal:
- Traffic Crashes shows each crash that occurred within city streets as reported in the electronic crash reporting system (E-Crash) at CPD. Citywide data are available starting September 2017.
- Red Light Camera Violations reflect the daily number of red light camera violations recorded by the City of Chicago Red Light Program for each camera since 2014.
- Speed Camera Violations reflect the daily number of speed camera violations recorded by each camera in Children’s Safety Zones since 2014.
- Historical Traffic Congestion Estimates estimates traffic congestion on Chicago’s arterial streets in real-time by monitoring and analyzing GPS traces received from Chicago Transit Authority (CTA) buses.
- Current Traffic Congestion Estimate shows current estimated speed for street segments covering 300 miles of arterial roads. Congestion estimates are produced every ten minutes.
The project implements the three layers of the Lambda Architecture:
- Batch layer – manages the master dataset (the source of truth), which is an immutable, append-only set of raw data. It pre-computes batch views from the master dataset.
- Serving layer – responds to ad-hoc queries by returning pre-computed views (from the batch layer) or building views from the processed data.
- Speed layer – deals with up-to-date data only to compensate for the high latency of the batch layer

23) Analyzing data from Crinacle
Scraping data from Crinacle's website can provide valuable insights and information about headphones and earphones. This data can be used for market analysis, product development, and customer segmentation. However, before any analysis can be conducted, the data needs to be processed, validated, and transformed. This is where a data pipeline comes in handy.
The first step in the data pipeline is to scrape data from Crinacle's website. This can be done using web scraping tools like Beautiful Soup or Scrapy. The data can then be stored in a CSV or JSON format and loaded to AWS S3 for storage. Once the data is loaded to AWS S3, it needs to be parsed and validated. Pydantic is a Python library that can be used for data validation and serialization. By defining data models using Pydantic, we can ensure that the data is in the correct format and structure. The parsed and validated data is then transformed into silver data, which is ready for analysis. The silver data can be loaded to AWS S3 for storage and backup. Additionally, the silver data can also be loaded to AWS Redshift, which is a data warehouse that enables fast querying and analysis of large datasets. AWS RDS can also be used to store the silver data for future projects. Finally, the data needs to be transformed and tested using dbt (data build tool). dbt is a tool that enables data analysts and engineers to build and manage data pipelines in a modular and scalable way. With dbt, we can transform the silver data into a format that is optimized for analysis and testing.
