How Many Legal Immigrants Are Eligible to Naturalize?

The map below uses data from the U.S. Department of Homeland Security, Office of Immigration Statistics (as processed and refined in collaboration with the Center for the Study of Immigrant Integration at the University of Southern California) to illustrate the number of legal immigrants eligible to naturalize in the United States as of year 2010.  (Click here for important information on the data.)

Upon clicking a county, the map displays an estimate of persons who obtained legal permanent residence in that location and the number of those persons who have subsequently naturalized.  Note that persons who naturalized may have done so after moving to another county. Note also that some of those persons who have not naturalized may not have lived sufficiently long in the U.S. (five years for more persons) to have become a citizen here.
