LPR Population Estimates
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.

DHS/USCIS/PIA 009 Central Index System
The Department of Homeland Security (DHS) U.S. Citizenship and Immigration Services (USCIS) maintains the Central Index System (CIS). CIS is a repository of electronic data that contains an index of basic data elements related to an individual as he or she passes through the immigration process. CIS contains information on the status of applicants and petitioners seeking immigrant and non-immigrant benefits, including: lawful permanent residents, naturalized citizens, United States border crossers, aliens who illegally entered the United States, aliens who have been issued employment authorization documents, individuals who petitioned for benefits on behalf of family members, and other individuals subject to the provisions of the Immigration and Nationality Act (INA). Recently USCIS migrated records from a legacy mainframe database to a cloud platform and renamed legacy CIS to CIS 2. CIS2 continues to look and function like the CIS mainframe application, with subtle formatting enhancements.
