ACS is a nationwide survey collecting and producing population and housing information every year. It has become the largest household survey in the United States, with an annual sample size of about 3 million addresses. Every year, ACS can support the release of single-year estimates for geographic areas with populations of 65,000 or more.
ACS uses three modes of data collection from households:
- Mail: self-enumeration through mail-out/mail-back.
- Telephone: computer-assisted telephone interviewing (CATI).
- Personal visits: computer-assisted personal interviewing (CAPI).
Survey Sample Design
ACS shifted from a demonstration program with a different sample design and sample size to the full sample size and design in 2005. ACS uses a series of monthly samples to produce annually updated data. Each month, ACS staff select a systematic sample of addresses from the most current Master Address File. The sample represents the entire United States.
A larger proportion of addresses are sampled for small governmental units (American Indian reservations, counties, and towns). The monthly sample size is designed to approximate the sampling ratio of Census 2000, including the oversampling of small governmental units.
