The Migration Policy Institute has published an online tool that provides state and county-level data about the estimated 11.4 million unauthorized, or undocumented, immigrants residing in the United States. Data is available for the 41 states and 94 counties with the largest number of unauthorized immigrants. Data includes year of entry, countries of origin, levels of education, industries of employment, incomes, parental and marital status, and health care coverage. For example, only 72% speak English less than “very well” and are likely to need language assistance services. While most of these individuals who have primary languages other than English speak English (75%), the next most common languages are Hindi, Chinese, and Korean. Up to 63% of these immigrants are uninsured.
The tool also provides estimates of the numbers of immigrants that could be eligible for the temporary, discretionary relief from deportation announced by President Barack Obama in November 2014. Nationally, an estimated 3.7 million immigrants could be eligible for the Deferred Action for Parental Accountability program and an estimated 1.5 million immigrants could be eligible for the expanded Deferred Action for Childhood Arrivals program.
The data tool is based on a methodology that imputes unauthorized status using U.S. Census Bureau 2008-12 American Community Survey and 2008 Survey of Income and Program Participation data.
