2010 Census and ACS The 2010 Census shows the number of people who live in the U.S. and the American Community Survey shows how people live

2010 Census Use data from the 2010 Census to obtain counts of population and housing units and their basic characteristics (sex, age, race, Hispanic origin, household composition, occupancy and homeowner status)

2010 Census April 1, 2010 An “actual enumeration” (The 2010 Census aims to count all U.S. residents—citizens and non- citizens alike) Only 10 questions on the 2010 Census form

ACS Use data from the American Community Survey to obtain detailed demographic, social, economic, and housing characteristics, such as income, poverty, employment, and educational attainment.

ACS An ongoing survey that provides data every year A sample of the population All ACS data are survey estimates. To help you interpret the reliability of the estimate, the Census Bureau publishes a margin of error (MOE) for every ACS estimate.

Population Thresholds for ACS Estimates 1-year estimates 3-year estimates 5-year estimates 65,000 + people XXX 20,000+ people XX Less than 20,000 people X
