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 describe 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.

Enforcement Lifecycle Reports
Congress has directed the DHS Office of Strategy, Policy, and Plans to report on the end-to-end enforcement lifecycle. OIS’ Enforcement Lifecycle methodology matches unique border encounters to their associated enforcement outcomes.
The FY 2021 report describes the final or most current enforcement outcomes, as of December 31, 2021, associated with the 5.7 million Southwest Border encounters occurring between 2013 and 2021. Encounters are analyzed by nationality, family status, and detention histories. The majority (56 percent) of pre-pandemic encounters had resulted in repatriation by December 31, 2022, while 68 percent of pandemic era encounters has resulted either in repatriations under Title 8 authority or in immediate expulsion under Title 42 public health authority. The report further examines enforcement trends over time by comparing enforcement outcomes at fixed time intervals following encounters occurring from 2013 to 2018.
