The Data USA API allows users to access slices of data across multiple government sources. Data is available in both JSON and CSV formats.
PLEASE NOTE: The existing Data USA API (api.datausa.io) will go into legacy mode starting in November 2018 and will be replaced by a newer version of the API with access to new & expanded data.
There are 3 different endpoints for the API, each one fulfilling a different role of extracting data from the site:
Data - retrieves variables from the most suitable database table (the "logic layer"), based on user-defined filters, crosswalking and substituting when necessary.
Search - returns a list of fuzzy-matched results, based on a string query and optional filters.
