Immigration Data and Statistics Collection

The Office of Immigration Statistics (OIS) carries out two main functions: to collect and disseminate to Congress and the public data and information useful in evaluating the social, economic, environmental, and demographic impact of immigration laws; and to establish standards of reliability and validity for immigration statistics collected by the Department’s operational Components.

  • Migrant Protection Protocols Cohort Reports

    Under the Migrant Protection Protocols (MPP), certain noncitizens encountered at the Southwest Border await their immigration proceedings in Mexico rather than in the United States. These reports describes Migrant Protection Protocols (MPP) processing and outcomes for noncitizens enrolled in MPP within given time periods, summarizing information on enrollee nationalities, fear claims, vaccinations, and processing outcomes (returns to Mexico or disenrollments) by month of MPP enrollment. Additional reports will be added regularly to include information about individuals enrolled in future months along with updated information about earlier enrollees as they move through additional stages of the MPP process.

    The Excel files with the readable tables may be published slightly before the narrative report is available.

  • Yearbook of Immigration Statistics 2020

    The 2020 Yearbook of Immigration Statistics is a compendium of tables that provide data on foreign nationals who are granted lawful permanent residence (i.e., immigrants who receive a “green card”), admitted as temporary nonimmigrants, granted asylum or refugee status, or are naturalized. The Yearbook also presents data on immigration enforcement actions, including apprehensions and arrests, removals, and returns.

  • Border Security Metrics Report

    The Fiscal Year 2017 National Defense Authorization Act directs the Department of Homeland Security “to develop metrics … to measure the effectiveness of security between ports of entry, at ports of entry, in the maritime environment and to measure the effectiveness of the aviation assets and operations of Air and Marine Operations of U.S. Customs and Border Protection.” This report meets this direction by providing the most comprehensive, rigorous set of border security metrics ever produced by the Department, along with a thorough discussion of the strengths and limitations of the Department’s available methodological approaches.

  • Enforcement Lifecycle Reports

    Congress has directed the DHS Office of Strategy, Policy, and Plans to report on the end-to-end enforcement lifecycle. OIS’s Enforcement Lifecycle methodology matches unique border encounters to their associated enforcement outcomes.

    The FY 2020 report describes the final or most current outcomes, as of March 31, 2020, associated with the 3.5 million Southwest Border encounters occurring between 2014 and 2019. Overall, 59 percent of Southwest Border encounters had been resolved through a final outcome of repatriation or relief/protection from removal as of the end of 2020 Q2. Repatriations accounted for 51 percent of encounters (or 1.8 million) versus 49 percent (or 1.7 million) of encounters that had no confirmed departure, including 8.1 percent that had been granted relief or other protection from removal (284,000 encounters). The report analyzes outcomes for different groups of encounters, including breakdowns by nationality, family status, and whether or not the alien made a fear claim.

  • Immigration Enforcement Actions

    The Department of Homeland Security (DHS) engages in immigration enforcement actions to prevent unlawful entry into the United States and to apprehend and repatriate noncitizens who have violated or failed to comply with U.S. immigration laws. Primary responsibility for the enforcement of immigration law within DHS rests with U.S. Customs and Border Protection (CBP), U.S. Immigration and Customs Enforcement (ICE), and U.S. Citizenship and Immigration Services (USCIS). CBP enforces immigration laws at and between the ports of entry, ICE is responsible for interior enforcement and for detention and removal operations, and USCIS adjudicates applications and petitions for immigration and naturalization benefits.

  • LPR by State, County, Country of Birth, and Major Class of Admission (Top 200 Counties)

    Lawful permanent residents (LPRs), also known as “green card” holders, are non-citizens who are lawfully authorized to live permanently within the United States.

    The tables below offer county-level data for the top 200 counties of residence of new LPRs by major class of admission and by country of birth. OIS assigns county of residence using zip codes USCIS receives in applications for admission as an LPR or adjustment to LPR status.

  • Adjustments to Lawful Permanent Residence by Year of Entry

    The tables offer the year of entry into the United States of those adjusting to LPR status from FY 2000 to FY 2019. Tables are available for the top 10 countries of birth and by world regions.
