The reports below present estimates of the lawful permanent resident (LPR) population living in the United States on January 1 of the given year. LPRs, also known as “green card” holders, are immigrants who have been granted lawful permanent residence in the United States but have not yet become U.S. citizens. Estimates of the total LPR population and the LPR population eligible to apply to naturalize are tabulated by country of birth, state of residence, and the year LPR status was obtained. Data for the estimates were obtained primarily from administrative records of U.S. Citizenship and Immigration Services of the Department of Homeland Security.
