The Census Bureau has updated the application programming interface (API) with profiles and summary files from the 2013 American Community Survey 1-year estimates. The American Community Survey gives communities the current information they need to plan investments and services. Retailers, homebuilders, police departments, and town and city planners are among the many private- and public-sector decision makers who count on these annual results.
