What is the American Community Survey? A large, continuous survey that: • produces characteristics of population and housing (similar to Census 2000 long form) • produces estimates for small areas and small population groups • samples approximately 3.54 million resident addresses per year (about 290,000 per month)
Puerto Rico Community Survey • Equivalent of ACS for Puerto Rico • Form available in both English and Spanish • Tables available in both English and Spanish in AFF
Census 2000 In Census 2000, the census used 2 forms • “Short” form – asked for basic demographic and housing information, such as age, sex, race, how many people lived in the housing unit, and if the housing unit was owned or rented by the resident • “Long” form – collected the same information as the short form but also collected more in-depth information such as income, education, and language spoken at home Only a small portion of the population, called a sample, received the long form.
2010 Census and ACS • 2010 Census focused on counting the U.S. population • The “long” form data are now collected by the ACS • Puerto Rico is the only U.S. territory where the ACS is conducted • 2010 Census had a long form for U.S. territories such as Guam and U.S. Virgin Islands • 2010 Census had same “short form” questions as the ACS
ACS Estimates Are NOT the 2010 Census Population Counts • The 2010 Census counts the population to support apportionment and redistricting • The ACS supplements this information with annually updated estimates on the nation’s population and housing characteristics • The purpose of the ACS is not to count every person in a community or town but rather, to provide a portrait of the community’s characteristics 7

Who Relies on ACS Data Products? • Local governments – State and local leaders use ACS data to determine the needs of their communities, such as where to build new roads, schools, hospitals, offices, and community centers, or what schools need to plan for bilingual education. • Emergency planners – Emergency planners use ACS data for natural disaster planning and response. The number of households and relative economic vulnerability located in small areas inform the plans for moving large numbers of people and for providing efficient and appropriate responses. • Businesses – Companies use ACS data to make investment decisions in assessing such factors as the local labor force, new markets, and the needs of prospective customers. • Learn more –http://www.census.gov/acs/www/about_the_ survey/acs_helps_communities/
