CMS derives its estimates from data collected annually in the US Census Bureau’s American Community Survey (ACS).[i] The ACS is an annual statistical survey covering approximately 1 percent of the total US population. The methodology involved three major steps:
- Applying a series of “logical edits” to identify and remove as many legal residents as possible from the ACS data for non-citizens who arrived after 1981;
- Deriving separate population controls, for 145 countries or areas, for undocumented residents surveyed in the 2010 ACS;
- Using those population controls to select records in the ACS micro-data (public use microdata sample (PUMS)) to be classified as undocumented residents; and
- Adjusting for undercount of undocumented immigrants in the ACS.
The term “logical edit” refers to the process of determining probable legal status by examining survey data. Respondents were assigned to the legal resident category if they worked in occupations that generally require legal status, were legal temporary migrants, were immediate relatives of US citizens, received public benefits, were from countries where most arrivals would be refugees, or were age 60 or older at entry.
