US Census Bureau API - Developers

US Census Bureau
The US Census Bureau surveys the US population for demographic information and provides this information to the public, as well as using the data for decision making. The US Census Bureau API allows developers to access and integrate the data from the US Census Bureau, beginning with the 2010 Census, with other applications and to create new applications. Some example API methods include retrieving data by geographic location, retrieving summary files, and retrieving demographic information.
