American Community Survey (ACS)
Definition
The American Community Survey is an ongoing annual survey conducted by the US Census Bureau that collects detailed demographic, social, economic, and housing information from approximately 3.5 million households each year.
Why It Matters
The ACS is the primary source of detailed demographic data between decennial censuses. It determines how billions in federal funding are distributed and provides the data underlying most "by state" and "by city" demographic rankings.
How It's Measured
The Census Bureau mails questionnaires to randomly selected addresses. The 5-Year estimates combine 60 months of data for maximum reliability, especially for small geographies like cities and counties.
