AP data maps 4.5 million migrants released into US interior

Over 4.5 million migrants were released into the United States after crossing the Mexican border between October 2018 and July 2025, according to federal records obtained by the Associated Press via a Freedom of Information Act request and published by WTOP. The dataset includes self-reported destination ZIP codes alongside citizenship, age, gender, and where and when migrants were encountered by border authorities. It shows Florida as the most popular state overall, while New York, Miami and other established hubs continued to draw large numbers.

The same records also map a quieter shift: migrants increasingly naming smaller cities with thinner support networks and less administrative capacity. WTOP cites destinations such as Elkhart in Indiana, Knoxville in Tennessee and Dodge City in Kansas, places that historically absorbed immigration at a slower pace and through local employers rather than crisis-driven arrivals. In Queens, New York, the AP data shows arrivals from at least 25 nationalities, including more than 7,000 each from Ecuador, China, Colombia, Venezuela and India; Philadelphia recorded at least 11 nationalities with 1,000 or more new arrivals, including Brazil, Haiti, the Dominican Republic, Russia and Venezuela.

The paperwork requirement that underpins the dataset is also its weakness. Migrants must provide U.S. Customs and Border Protection with a street address upon release, but authorities told AP they lacked resources to verify the addresses. The address becomes a key input to everything that follows—immigration court notices, check-ins, and eventual work authorization—yet it is treated as a self-declared field in a system built for volume. Some migrants never arrived at the addresses they provided, AP reports; others moved within the US or left the country voluntarily or involuntarily. Many, however, did remain where they first said they were going, which is why the ZIP-code map is politically potent: it turns a national policy into a list of local consequences.

The demographic composition in the records points to why local services feel the pressure differently than in earlier eras. Nearly 60% of migrants released at the border were women and children, according to AP’s analysis, a shift from flows dominated by single adult men. That changes immediate needs—school enrollment, pediatric care, housing crowding—and it also changes the enforcement problem: families are harder to detain, harder to remove quickly, and more likely to be routed into long legal processes.

A second AP piece, presented as a photo essay, offers a close-up of how the numbers land. In Lockland, Ohio, a small town outside Cincinnati, a shop called Bikes and Stuff gives away refurbished bicycles and has become a gathering point for a West African community that grew rapidly after thousands of migrants, most from Mauritania, arrived in recent years. The story describes early crowding and reliance on a local food bank, followed by a more stable pattern once work permits and jobs arrived; one migrant is described working long shifts at a meatpacking plant while saving for a car, while another bought a house.

The federal records cover releases, not final settlement, and they do not show who ultimately wins asylum or leaves. But they do show how a system that cannot verify an address still uses it to distribute people across the country.

In Lockland, the bikes are handed out on Friday afternoons, while immigration check-ins and court dates are scheduled elsewhere by agencies that never had to confirm where anyone lived.
