To improve access to data and encourage innovation, the Census Bureau provides Application Programming Interface (API) access to selected data sets, including the 2010 Census Summary File 1 and the American Community Survey (five year data). The API allows developers to design Web and mobile apps to explore or learn more about America's changing population and economy. Visit our Developer Site to learn more.
