Here's a national map of the shelters housing immigrant children

Since the White House announced its "zero tolerance" policy in May, more than 2,300 children have been separated from their parents at the border, resulting in a stream of immigrant children requiring government care at shelters across the country.

After being processed at border control, which takes approximately 72 hours, children are bused or flown to one of 100 facilities across 17 states that house “unaccompanied alien children.” After that, children are placed in permanent housing and go through the judicial system.

On Tuesday, U.S. Sen. Bill Nelson’s staff said Health and Human Services officials told them that some children have yet to be reunited or in contact with their parents because HHS has been unable to locate them, possibly because the adults have been deported.

Last week, the Miami Herald reported that at least 10 toddlers were being housed at two "tender-age shelters" in Miami Gardens and Cutler Bay.

Below is a map of the 87 child-care facilities across the nation that house and supervise children as part of the unaccompanied immigrant minors program. The data was obtained by Reveal, the website, public radio program, podcast and social-media platform of The Center for Investigative Reporting, and the Associated Press.

The information shows shelters and other types of facilities, excluding foster-care placement agencies, that contracted with the government as of February 2018, with some more recent updates.

The counts of children presented below are not limited to those who have been separated from their parents under the government's recently rescinded policy that separated families. The counts include many of those children, but also include thousands of children who came to the country as unaccompanied minors and are housed in the same federally funded shelters.

Capacity and occupancy data is missing for some facilities; AP and Reveal will continue to update this information as part of an ongoing effort.
