WASHINGTON — The cost of holding migrant children who have been separated from their parents in newly created “tent cities” is $775 per person per night, according to an official at the Department of Health and Human Services — far higher than the cost of keeping children with their parents in detention centers or holding them in more permanent buildings.

It costs $256 per person per night to hold children in permanent HHS facilities like Casa Padre in Brownsville, Texas. And keeping children with their parents in detention centers like the one run by U.S. Customs and Immigration Enforcement in Dilley, Texas cost $298 per resident per night, according to an agency estimate when it awarded the contract for the facility in 2014.
