The American Community Survey (ACS) produces annually updated data products describing the demographic, social, economic, and housing characteristics of the United States. The Puerto Rico Community survey (PRCS) is the equivalent survey in the Puerto Rico. Both the ACS and the PRCS use three sequential modes of date collection-mail, telephone, and personal visit. In the first mode of data collection a questionnaire is sent to a sample address for a response to be returned by mail. If the housing unit does not respond by mail and a phone number is available, the case is followed up by telephone using Computer Assisted Telephone Interviewing (CATI) methods. For a subsample of the initial sample cases that cannot be completed by mail or telephone, an interviewer is sent to the address to conduct an interview in person using Computer Assisted Personal Interviewing (CAPI) methods.
