The National Data Catalog is an open platform for government data sets and APIs. It makes it easy to find datasets by and about government, across all levels (federal, state, and local) and across all branches (executive, legislative, and judicial). The data here is imported from multiple sources and curated by our staff.
Our catalog contains 2470 data sets and was last updated 1 day ago. We aggregate sources from: data.gov, data.dc.gov, utah.gov, datasf.org, texas.gov, texastransparency.gov, colorado.ckan.net, and the Sunlight Foundation and its partners.
Signing up for an account on the National Data Catalog allows you to mark data sources as favorites, participate in discussions, and contribute to documentation. It also gives you an API key for programmatic access.
The National Data Catalog is a project of the Sunlight Labs at the Sunlight Foundation. Our software platform is open source. It consists of a web application, an API, and data importers.
