Interactive Map: Eligible-To-Naturalize Populations in the U.S.

The University of Southern California’s Center for the Study of Immigrant Integration (CSII) produced two interactive maps showing estimates of eligible-to-naturalize adults in the United States. One map, released in December 2018, presents the number and characteristics of the eligible to naturalize population by their probability of naturalization. In a first of-its-kind analysis, CSII disaggregates the eligible-to-naturalize adult population by probability of naturalizing in the next two-to-three years: low probability, medium probability, and high probability. The tool also provides a table of each population’s demographic information, including age, race, education attainment, poverty status, English speaking ability, top five places of origin, and top five languages spoken at home (other than or in addition to English). The map can be displayed at the Public Use Microdata Area (PUMA) level, the congressional district level, and the state level. The other map, from 2016, presents estimates of the size and region-of-origin composition of eligible-to-naturalize adults in the United States. The map displays the data using three measures: “Total number” of adults eligible to naturalize; “As % of adults” to give a sense of the concentration of adults eligible to naturalize; and “As % increase in CVAP, if naturalized” showing the potential effect on the Citizen Voting Age Population (CVAP) to give a sense of the maximum percentage by which the eligible-to-naturalize adults could increase the voting-eligible population if they all naturalized. The map can be displayed at four different geographies: Public Use Microdata Areas (PUMAs), counties, metropolitan (metro) areas, and states.

Detailed Data on the Naturalization-Eligible and Potential Future Voters in 2,332 Sub-state Areas

On November 3, 2015, the Center for Migration Studies of New York (CMS) published a paper in its Journal on Migration and Human Security with estimates of the US “eligible-to-naturalize” population.[1] It subsequently released two spreadsheets on the naturalization-eligible with state-level data on country of origin; languages spoken at home; ability to speak English; educational attainment; age; sex; period of entry; marital status; access to a computer or the internet; poverty status; median income and health insurance coverage.

Later, it released detailed estimates and characteristics of naturalization-eligible immigrants residing in 2,332 US sub-state regions; i.e., public use microdata areas (PUMAs) which cover geographic areas that contain at least 100,000 persons. PUMAs do not align with Congressional districts, but the estimates provide data on the naturalization-eligible in virtually every city and rural area in the United States.

CMS also put this data into an interactive map format.
