Ensuring the American Community Survey (ACS) collects accurate data
The American Community Survey (ACS) is a mandatory, ongoing statistical survey that samples a small percentage of the population every year, giving communities the information they need to plan investments and services.
The survey collects demographic, economic, housing, and social data. These data are invaluable to federal, state, and local governments; researchers; and businesses. Given the importance of the data and the need to ensure continuity with previous data collections, changes to the ACS are made only after rigorous testing.
