Free Datasets

by Boxplot    Sep 1, 2019   
A list of freely available data on the web. The first list is sites we think are the best for accessing quality datasets. Below that are additional sources by category.

Best Sources


By far our personal favorite! There are dozens if not hundreds of quality datasets available here.


You have to create an account, but it’s free and they have a pretty extensive list of datasets you can download directly from their site.

US Open Data

The open data site for the United States government. There are dozens if not hundreds of datasets linked here.

Yelp Open Data

This is a single dataset (but a large one) offered by Yelp.

General Social Survey

This is another single dataset (and another large one!) offered by the University of Chicago.

Federal Committee on Statistical Methodology

You’ll have to work a bit harder to use one of these datasets – you have to choose the release, then choose the data tab, and then you may get the data in a relatively dirty format and have to clean it. But there are a lot of options on this site, and more datasets are added regularly.

Police Data Initiative

A list of datasets from local police departments.

Makeover Monday

This is the website for a data visualization book. They make the data easy to access, but there might be duplicate datasets from some of the other sources on this page (like Data.World).


They have a few pages on their website that offer lists of datasets. There’s “Datasets for Data Mining and Data Science“, “Data: APIs, Hubs, Marketplaces, and Platforms“, and “Data: Government, State, City, Local and Public“.


You have to dig a bit to find the datasets on this site. You also may need to create an account to access them/get the full list of datasets.

This Quora Post

Somebody asked this exact question on Quora and got a pretty extensive list of data sources as a response!
