Search. Discover. Use.

We want to ensure the District’s data is as open, discoverable and usable as possible in hopes of fostering greater participation and collaboration. Search the site's datasets by topic, or explore featured datasets or review the full list of DC Data sets.

A Growing Site

This new site is a work in progress. We are working diligently to add new data sets, improve usability and bring forward some of the legacy datasets that did not make the initial move. Take a look at some of our newly added and recently updated datasets. If you don’t see a set you have used before, you can view and download all previous data sets at our legacy site. We plan to retire the legacy site only after everything has been moved and optimized.


If you have questions, suggestions, requests or any other feedback, please contact the Chief Data Officer or shoot us a tweet at @opendatadc.

For years, the District of Columbia has provided public access to the Districts data through the Internet. The District is utilizing open source technology to increase public access to the vast amount of information it creates and receives from our agency partners. In doing so, we hope residents can make more informed decisions about their government and our community.
