Over 11,000 people participated in the first annual National Day of Civic Hacking on June 1st and 2nd, 2013. At the event, developers collaborated with government agencies and entrepreneurs to create applications that help solve civic and social problems impacting local communities. Developers used a variety of public APIs and datasets to create their applications, including the US Census Bureau API, which was used to create an interactive application and several infographics. The US Census Bureau API is the first API created by the US Census Bureau and was released to the public back in July 2012.
