The U.S. Census Bureau added several data sets to its application programming interface, including 2013 population estimates and 2012 nonemployer statistics.

The Census Bureau API allows developers to create a variety of apps and tools, such as ones that allow homebuyers to find detailed demographic information about a potential new neighborhood. By combining Census Bureau statistics with other data sets, developers can create tools for researchers to look at a variety of topics and how they impact a community.

Data sets now available in the API are:

• July 1, 2013, national, state and county population estimates
• 2012-2060 national population projections
• 2007 Economic Census national, state, county, place and region economy-wide key statistics
• 2012 Economic Census national economy-wide key statistics
• 2011 County Business Patterns at the national, state and county level (2012 forthcoming)
• 2012 national, state and county nonemployer statistics (businesses without paid employees)

These data sets include three decades (1990, 2000 and 2010) of census statistics and statistics from the American Community Survey covering one-, three- and five-year periods of data collection. Developers can access the API online and share ideas through the Census Bureau’s Developers Forum.
