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

Between each 10-year census, the U.S. Census Bureau conducts more than 100 additional
surveys of households and businesses across the nation each year. One of the surveys that
is often confused with the census is the American Community Survey, which reaches about
one in every 38 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 surveys to plan and fund such things as school construction, transportation
systems, public housing, police and fire precincts, and future utility needs. Federal law
requires participation in both.
