2. To facilitate and improve the comparability of data at the regional level through the selection of a core set of census topics and the harmonization of definitions and classifications
Chapter VIII focuses on international and internal migration and recommended
core, non-core, and derived non-core topics.

U.S. Decennial Census – Quick Facts
Universe: Entire U.S. resident population(households and group quarters)

for Census 2010Geography: National and extensive sub-nationalPurpose: Apportionment of seats in the House of

Census 2010– Includes age, sex, race, Hispanic origin, household
relationship, tenure (owner/renter status)
American Community Survey (ACS) is one component of the reengineered decennial census• ACS provides annual demographic, social, economic,
and housing characteristics data• ACS questions are comparable to the decennial long
form sample data, most items included in both• Note sample size in ACS is smaller, however

American Community Survey – Quick Facts
Purpose: Provide timely data at national and extensive sub-national geography levels
Universe: U.S. resident population(3 million annually in
sample since 2005)
Frequency: Yearly releases of data
Geography: Nation, state, and limited county and place (2000 to 2005) and extensive sub-national (2008 forward)

American Community Survey – Who Is Interviewed?
• Resident population living in both households and group quarters facilities (since 2006)
