Yes. U.S. Customs and Border Protection (CBP), Pew Research Center, and the Migration Policy Institute (MPI) publish the main data. Numbers distinguish encounters (people stopped at the border) from the larger unauthorized population already living in the U.S.20

Border encounters
Southwest border encounters peaked in FY2022–FY2023 at roughly 2.0–2.5 million per year. They fell to about 1.5 million in FY2024 and dropped sharply in FY2025 to the lowest level since 1970 (Border Patrol recorded 237,538 southwest encounters that year). FY2026 year-to-date figures remain low, with monthly Border Patrol southwest apprehensions typically in the 6,000–10,000 range.14

Countries of origin
Mexico remains the single largest source but no longer a majority. In the unauthorized population as of 2023–2024 estimates:

• Mexico: ~35–40% (about 5.1–5.5 million)
• Guatemala, Honduras, and El Salvador: next largest groups
• Venezuela, Colombia, Nicaragua, and Brazil grew rapidly after 2019.27

During the high-encounter years (2021–2024), top nationalities at the southwest border included Mexico, Venezuela, Guatemala, Honduras, Cuba, Haiti, Colombia, and Ecuador. Extra-regional arrivals (India, China, and others) also rose but stayed a smaller share.

Ethnicity
The large majority of both recent border encounters and the overall unauthorized population are Hispanic/Latino from Latin America. Smaller shares come from Asia, the Caribbean, Africa, and Europe.

Faith
Official government statistics do not record religion. Surveys and church analyses of Latin American-origin migrants find they are predominantly Christian. A 2025 report from Catholic and evangelical groups estimated that about 8 in 10 people at risk of deportation were Christian and about 6 in 10 Catholic. Protestant/Evangelical affiliation is higher in some Central American countries than in Mexico.41

Estimates of the total unauthorized population reached 14 million (Pew, 2023) to 15.8 million (MPI, mid-2024) before likely beginning to decline in 2025 under tighter enforcement. Most of that population has lived in the U.S. for years; recent arrivals account for the post-2019 growth.
