Table 1: Transfers

During the most recent 12 month period for which data are available, a total of 4,699 detainees were transferred by Immigration and Customs Enforcement (ICE) from the Adelanto Detention Facility where they had been temporarily housed to other facilities. The average stay for these individuals before their transfer was 38 days. The use of this facility for the temporary housing of federal immigration detainees was arranged through an intergovernmental service agreement (IGSA) under which payments by ICE to another governmental agency are made for housing federal detainees. While the facility is government owned, it is operated by the The GEO Group, Inc. that was in the business of providing detention services for housing federal detainees.

Transfers made up 74 percent of the 6,368 detainees who in one way or another left this facility during the last 12 months. This report focuses just on these transfers. The remaining individuals who departed from the Adelanto Detention Facility last year actually left ICE detention. These individuals were deported from the country, released under supervision while their cases was being decided, or left ICE detention for a variety of other reasons. For more information on this facility please see additional TRAC reports in this series.

This report series is based upon analyses conducted by the Transactional Records Access Clearinghouse (TRAC) at Syracuse University of 1.7 million government records tracking each individual who passed through an ICE detention facility during fiscal year 2015. This most recent 12 month period for which comprehensive data are available covers October 2014 through September 2015. See About the Data.

How This Facility Ranks Nationally

Detainee transfer rankings. The Adelanto Detention Facility was one of 637 facilities nationwide that housed ICE detainees during the most recent 12 month period. Of these 637, there were 409 facilities that had at least 10 ICE detainee transfers last year. Excluding those facilities with fewer than 10 transfers, the Adelanto Detention Facility last year ranked in the top 4 percent nationwide in the number of individuals it transferred to other ICE facilities. This means that 4 percent of the locations contributed the same or a larger numbers of transfers, while 96 percent had a smaller number. See Table 1.

Average length of stay before transfer. Once detainees arrived at the Adelanto Detention Facility their average length of stay before being transferred on to another ICE facility was 38 days last year. Ranking facilities from longest to shortest detention stays for their transfer population, this average of 38 days placed Adelanto Detention Facility in the top 24 percent of all facilities nationwide. That is, for detainees who are transferred, 24 percent of ICE detention facilities have the same or longer average stays last year, while 76 percent of detention facilities had shorter average stays.

Origins and Destinations

Were these detainees arrested locally? Where did those that ended up being transferred from the Adelanto Detention Facility last year originate? Information on the place of arrest was not included in the available data ICE released. However, we can examine whether the Adelanto Detention Facility was the first ICE facility in which these detainees were held. According to ICE records, for a few (18) of these detainees, the Adelanto Detention Facility was the first place they were sent when they were detained by ICE. Virtually all had been transferred in from another ICE detention facility.

We can also look at how quickly they arrived at this facility after they were first detained. A total of 79 percent arrived at the Adelanto Detention Facility at some point during the very first day they were detained by ICE. This percentage is also based on an analysis of the most recent 12 months for which data are available.

How soon did transfers occur? Nationally, the median number of days before an ICE detainee is transferred to another facility was 1 days last year. That means that half of all transfers occurred on or before the 1st day, while half had longer stays before they were transferred on to another ICE facility. Note that nationally the average stay at an ICE detention facility before an individual is transferred is longer - 12 days. This is because while most detainees have relatively short stays before ICE transfers them elsewhere, sometimes stays are lengthy and these lengthy stays raise the average to above the median stay.

For the Adelanto Detention Facility last year, the median stay before a detainee was transferred was 7 days. This is longer than the national figure. The average stay before transfers occurred was longer - 38 days - than the median stay. As noted above, this figure placed the facility in the top 24 percent among ICE detention facilities nationwide in the average number of days a detainee spent before he or she was transferred.

Where did those transferred get sent? ICE currently has great discretion about where in the United States transferred detainees are sent. For the period covered by these data, ICE divided the country into geographic regions or areas and assigned each to one of 152 document control offices or DCOs for the purpose of keeping track of detainees. Available data allow us to examine whether the transfer occurred within the same DCO or the transfer was to a different DCO. For the nation as a whole during the latest 12 months, 54 percent were within the same DCO, while the remaining 46 percent were to a different DCO.
