Learn about the estimated 11 million unauthorized immigrants living in the United States. Where do they live? When did they arrive in the United States, and from which origin countries? What are their levels of education, top industries of employment, incomes, parental and marital status, health care coverage, and more? Using a unique MPI methodology to assign legal status in the U.S. Census Bureau's American Community Survey data, this data tool provides detailed sociodemographic profiles for the United States, 41 states (plus the District of Columbia), and the 130 counties with the largest unauthorized populations as of 2019. And for topline estimates of unauthorized immigrant populations for 273 counties, click on the spreadsheet at right.

This data tool is based on a methodology that imputes unauthorized status using U.S. Census Bureau 2015-19 American Community Survey (ACS) and 2008 Survey of Income and Program Participation (SIPP) data, weighted to 2019 unauthorized immigrant population estimates provided by Jennifer Van Hook of The Pennsylvania State University. For more detail on the methods, see MPI, “MPI Methodology for Assigning Legal Status to Noncitizen Respondents in U.S. Census Bureau Survey Data.” These estimates have the same sampling and coverage errors as any other survey-based estimates that rely on ACS and other Census Bureau data.
