I already filled out a survey from the Census Bureau last year! Why have I been contacted again?

The U.S. Constitution mandates that a census or count of the population be conducted every 10 years. The 2020 Census consists of 11 quick and easy questions per household member. In between each decennial census, the U.S. Census Bureau conducts more than 100 surveys of households and businesses across the nation each year. A full list of the bureau’s surveys can be found on their website.


One of the surveys that is often confused with the decennial census is the American Community Survey (ACS). This annual survey reaches one out of every 480 households each year and asks very detailed questions on topics such as employment, income, housing, and place of birth.


State and local governments use data from both the decennial Census and the ACS to plan and fund such things as school construction, transportation systems, public housing, policy and fire precincts, and future utility needs. Participation in both the decennial census and the ACS is required by law.
