Who should complete the American Community Survey (ACS)?

A knowledgeable person 15 years old or older should complete the ACS. This person should live in the household and have a good understanding of the household finances. A nonhousehold person, such as a neighbor, landlord, or janitor is not eligible to be a respondent if the home is occupied. If the only person available at the sampled address is physically or mentally unable to respond for him/herself, he or she may designate a nonhousehold (proxy) respondent. The nonhousehold respondent must live or spend time in the sample unit caring for the disabled person and be knowledgeable about the household.
