This analysis is based on a KFF analysis of the 2018 American Community Survey (ACS), 1-year file. The ACS includes a 1% sample of the US population, the subset used here includes over 160,000 non-citizen observations. Industry and Occupation definitions are defined within ACS using the 2018 SOC and the 2017 NAICS – for more information see here. We define workers as adults (18+) who earned at least $1,000 during the year. Metro and non-metro areas are defined by the USDA Economic Research Service.

The ACS asks respondents about their health insurance coverage at the time of the survey. Respondents may report having more than one type of coverage; however, individuals are sorted into only one category of insurance coverage.
