Detention center population shift

As Oscar Campos Estrada’s immigration situation has changed, so has the makeup of the Northwest Detention Center where he was held for about a month in 2011.

To hold waves of immigrants coming across the border, southern regions have been sending detainees north to Tacoma, where the Tideflats facility holds about 1,300 people.

The number of detainees initially booked in the San Antonio, Texas, area and then sent to Tacoma doubled from about 600 in the 2012 fiscal year to more than 1,200 in 2013, according to U.S. Immigration and Customs Enforcement.

The San Diego and Phoenix areas of responsibility also have sent significantly more detainees to Tacoma in that time frame.

That means the portion of detainees at the center who initially were booked in the Pacific Northwest dropped from 90 percent in the 2012 fiscal year to 76 percent in 2013.
