How does the American Community Survey collect data?

The American Community Survey relies on a continuous, rolling sample approach. Each month, a portion of housing units is surveyed, and responses from across the year are combined to produce updated annual estimates for various geographic areas. This design lets the Census Bureau provide more current data than a once-a-decade census, covering many measures of population and housing. It’s not a census of every household, and it draws on direct survey responses rather than relying solely on administrative records; data are released as annual updates (and for smaller areas, multi-year estimates are available). This rolling monthly sampling is what makes the ACS able to provide yearly information for geographic units such as census tracts and block groups.
