• American Communities Survey (ACS) - samples the US population every year and will replace the long form in future censuses. Information about the geographic locations surveyed in a given year can be found under "survey basics-> sample size". Public Use Microdata (PUMs) are available through the ACS website. Microdata show the full range of responses made on individual questionnaires, including questions on age, sex, tenure, income, education, language spoken at home, journey to work, occupation, condominium status, shelter costs, vehicles available, and other subjects. The advantage of PUMS is that data users can tabulate data according to the characteristics they need to know about.

All identifying information is removed to ensure confidentiality.
