Here’s some updated data on unaccompanied migrant children.

New arrivals of kids at the US-Mexico border have declined somewhat after sharp growth in July. But more are arriving than were in May-June.

The number of kids in Border Patrol’s child-inadequate holding facilities jumped up in August, but now is back below 1,000.

After a bump in August, the number of kids in the Health and Human Services Department’s network of shelters, awaiting placement with US-based relatives or sponsors, is similar to late June. The population stubbornly remains between 14,000 and 15,000 kids.

Last week, HHS discharged more children per day from its shelters, on average, than in any prior week. 594 per day.

Subtract the number of kids discharged by HHS, from the number of unaccompanied kids newly apprehended by Border Patrol, and last week was the third straight week when the population in US government custody declined. That’s good.
