Estimates of the Unauthorized Immigrant Population Residing in the United States

The reports below provide estimates of the size of the unauthorized immigrant population residing in the United States by period of entry, region and country of origin, state of residence, age, and sex. The unauthorized resident immigrant population is defined as all foreign-born non-citizens who are not legal residents. Most unauthorized residents either entered the United States without inspection or were admitted temporarily and stayed past the date they were required to leave. Unauthorized immigrants applying for adjustment to LPR status under the Immigration and Nationality Act (INA) are unauthorized until they have been granted lawful permanent residence, even though they may have been authorized to work. Persons who are beneficiaries of Temporary Protected Status (TPS)—an estimated several hundred thousand—are not technically unauthorized but were excluded from the legally resident immigrant population because data are unavailable in sufficient detail to estimate this population.
