American Community Survey


The American Community Survey(ACS) is a nationwide annual survey designed to provide communities with a fresh look at how they are changing. The goals of the American Community Survey are to provide an information base to federal, state, and local governments for the administration and evaluation of their programs, to improve the 2010 Census, and to provide data users with timely demographic, housing, social, and economic data that can be compared across states, communities, and population groups. The American Community Survey will provide estimates of demographic, housing, social, and economic characteristics every year for all states, as well as for all cities, counties, metropolitan areas, and population groups.
This survey was done in all counties and covers both households and group quarters.
Geographic coverage is for nation, state, or metropolitan area.Microdata files from the American Community Survey show the full range of responses made on individual questionnaires. For example, how one household or one household member answered questions on occupation, place of work, and so forth. The files contain records for a sample of all housing units, with information on the characteristics of each unit and the people in it.

All identifying information is removed to ensure confidentiality. The records selected are a sample of those households that received the questionnaire. The questionnaire included questions on age, sex, tenure, income, education, language spoken at home, journey to work, occupation, condominium status, shelter costs, vehicles available, and other subjects.
