Kaggle
Kaggle is one of the most popular data science platforms. It hosts competitions and has a catalog of courses in a variety of industry fields, such as machine learning and AI.
The best thing about Kaggle is that it offers thousands of datasets, big and small, which you can download for free. Most of them are formatted as ‘.cvs’ files.
On the website, you’ll find many interesting datasets that are originally part of competitions for data science enthusiasts. One example is the famous Titanic dataset on which you can practice building a machine learning model to predict which passengers survived the shipwreck. Additionally, you can share your results with the Kaggle community and exchange knowledge.
So, if you’re looking for an all-in-one solution to learn, practice, and compete, then Kaggle is the right place to start with.
Google Dataset Search
Launched in 2018, the Google Dataset Search initiative made it possible to access and download free public datasets. You can choose from a variety of topics and formats including ‘.pdf’, '.csv’, '.jpg’, ‘.txt’, and more.
Using it is as simple as running a regular Google search: just write the name or topic you’re looking for in the bar. As you’re typing, it will keep suggesting datasets that have the specific keyword you’re looking for, thus you might discover something entirely new and exciting.
GitHub
Besides being a developer’s best friend, GitHub offers thousands of small and large datasets for your data analysis needs. On the left side, you can filter the results by “language” and “keyword”. This allows you to choose topics that interest you so that the content is curated based on your interests.
What is more, on GitHub you can share your work with the world, making it a great opportunity to build your data science portfolio.
World Bank Open Data
The World Bank Open Data is considered one of the richest, most diverse resources of statistical facts and public datasets. You can search by categories such as “country” or “indicator” in order to find demographic information such as:
- Population
- Income levels
- Healthcare status
- Education
- Economy
What’s really interesting about the World Bank website is that it offers free resources and tools for the public, such as Data Bank – a helpful tool to analyze and visualize large datasets.
Data.world
Through data.world, you can access free datasets, as well as work on some directly on the website. All you have to do is create a free account and you’ll be able to work on 3 free projects. Alternatively, there are pricing plans if you need to upgrade to a larger storage space.
By using the search bar, you can look for keywords, resources, organizations, or people. And if you want to be even more specific, you can click on the “Create advanced filter” button to find exactly what you’re looking for.
DataHub
DataHub is a SAAS data-publishing platform by Datopian where you can browse through the most diverse collection of public datasets organized by topic. The platform also features a blog where you can enjoy articles on various data science subjects.
What’s exciting about DataHub is that it provides you with a documentation section on how to use the platform, as well useful tutorials on how to use its features to build visualizations and manage large datasets online.
Humanitarian Data Exchange
If you’re looking for a platform where you can download, upload, use, and share data all in one place, then Humanitarian Data Exchange is a must-visit. You can search for free datasets and filter the results by location, format, organization, and licenses.
What makes this resource so unique is that, on the home page, you’ll find a tab called “Dataviz”. There, you can explore relevant COVID-19 data and discover insightful stories in the gallery, told by the great power of data visualization.
FiveThirtyEight
FiveThirtyEight is, without a doubt, the best data journalism website. It’s a bit different from the previous resources, however, that’s what makes it stand out.
This great platform publishes content in sports, politics, and science, providing you with the code and data used in creating the content. The best part is that it’s all publicly available. Just sign up with your email and you’ll get the newsletter sent directly to your inbox.
Now for the exciting part: the datasets. FiveThirtyEight has a large selection of data to choose from and regularly updates its resources – evidenced by the orange dot next to a dataset that is currently updating.
UCI Machine Learning Depository
This might be the least abundant resource we’ve covered so far, yet the UCI Machine Learning Depository is nevertheless quite helpful if you’re looking to build a machine learning model.
Despite not being as rich as other dataset libraries, UCI is one of the oldest data sources ever published on the internet. There’s actually a dataset online that goes back to 1987!
The user interface is pretty simple and organized. You can browse by the default task, attribute type, data type, and area of specialty. But in case you like a more elegant and modern web design, you’re in luck – the repository is currently testing a beta version with an entirely new look:
