The following links provide a digest of various data from the Census Bureau’s sample data program, the American Community Survey (ACS). Note that the ACS is now a separate program from the decennial Census, and is subject to a margin of error.

The Census Bureau provides data for small geographies by including sample data from 5 years of surveys (e.g. 2013 to 2017) to reduce this margin of error. Single-year ACS data is available for larger geographies (with greater than 65,000 people) at the Census Bureau’s American FactFinder.
