Detainees Leaving ICE Detention from the
Polk County Jail
Table 1: Number leaving ICE detention
from this facility
During the most recent 12 month period for which data are available, a total of 2,056 detainees housed
at the Polk County Jail left that facility because they were deported, were released under
supervision while their cases were being decided, or left ICE detention for one of a variety of other reasons.
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 Community Education Centers that was in the business of
providing detention services for housing federal detainees.
Those individuals who departed from this facility because they were leaving ICE detention made up 64 percent of
the 3,227 detainees housed at this facility during the last 12 months.
This report focuses on the reasons these individuals left ICE detention.
Sometimes this report speaks of these individuals as those "exiting" ICE detention, or simply as "exits."
The others remained in ICE detention but were transferred from
the Polk County Jail to other facilities.
This report covers those who left ICE custody.
It excludes individuals transferred to other ICE facilities.
For more information on this facility, including individuals that were transferred, 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
Rankings on the number leaving ICE detention. The Polk County Jail was one
of 637 facilities nationwide that housed ICE detainees during the most
recent 12 month period. Of these 637, there were 358 that had
at least 10 individuals who were deported or released.
Excluding those facilities with fewer than 10 exits, the
Polk County Jail last year ranked in the top 10 percent nationwide in
the number of individuals leaving ICE detention.
This means that 10 percent of the locations contributed the same or a
larger numbers of exits, while 90
percent had a smaller number. See Table 1.
Deportations. Nationally, the most common reason that a detainee left ICE detention was
that they were deported from the United States.
During the most recent 12 month period for which comprehensive data are available,
nationwide 56.3 percent of those leaving ICE detention were deported
or "voluntarily" departed.
By way of comparison, a higher percentage of detainees (95 percent) left
the country from the Polk County Jail because they were formally deported, or left under
the so-called "voluntary departure" procedure.
Were Detained Individuals from the Local Area?
Information on the place of arrest was not included in the available data ICE released.
However, we can examine whether the Polk County Jail was the first ICE facility in which
these detainees were held.
According to ICE records, for a few (3) of these detainees, the Polk County Jail
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.
Again, a total of 5 arrived at the Polk County Jail at some point
during the very first day they were detained by ICE.
There was considerable variability among detainees in the number of detention facilities
they had been held in before they were finally deported or released from this facility.
The number of facilities ranged as high as 6 separate locations for some detainees.
These figures again are based on an analysis of the most recent 12 months for which data are available.
For the United States as a whole, last year the average number of ICE facilities
detainees moved through was 1.8.
Detainees at the Polk County Jail on average had stayed at somewhat more (2.9)

Why Did Detainees Leave ICE Detention?
ICE records one of 29 reasons a detainee left ICE detention.
As shown in Table 3, these reasons fall into 13 general categories -- from leaving because
one is deported or removed, to leaving because one escaped or the individual died while in custody.
As mentioned earlier, the most common reason detainees left the Polk County Jail
was that they were deported.
A total of 1,955 individuals (95 percent) were deported or removed from the Polk County Jail during the most recent 12 month period for which data are available.
(ICE data did not distinguish between deportations and removals, and the terms are used interchangeably in this report.)
Transferred to criminal custody.
A total of 78 individuals (4 percent) left this facility
last year because they were turned over to U.S. Marshals or to some other government agency.
This typically occurs because there is an outstanding criminal case against the individual, or the
individual is needed as a material witness in a criminal case.
Orders are additional mechanisms that are sometimes used to release a person while their case is pending, or awaiting removal.
Under an "order of recognizance" an individual is released with reporting conditions while in deportation proceedings and
awaiting a final decision.
A second type of order ("order of supervision") releases an individual after a final order of removal.
Here an individual is released because ICE has not met the time limits the law imposes for deporting the individual.
There were 12 (1 percent) who left the Polk County Jail detention for these reasons: one with an order
of recognizance, and 11 with orders of supervision.
Escape and death. Nationally, there were 65 individuals who
escaped ICE detention during the latest 12 month period for which data are available,
and 6 individuals were recorded as having died in detention.
No one was recorded by the Polk County Jail as either escaping or dying last year.
As shown in Table 3, no one was recorded as leaving the Polk County Jail during the past 12 months for the following
Alternative ATD custody, Release to ORR, Paroled, Proceedings Terminated, Voluntary Return and Withdrawal. See "Reasons for Leaving ICE Detention" for a description of these categories.

Comparing Release Reasons Against The National Picture
In many respects release reasons for the Polk County Jail departed from the national picture.
It was the case that a higher proportion left because they were deported from
this facility (95 percent) than was true for the U.S. as a whole (55 percent).
No one left as a voluntary departure from this facility, while this was true
for 1 percent of all individuals nationally.
In addition, differences were seen for detainees released on orders of recognizance or supervision (1
versus 20 percent), individuals released on bond (0
versus 11 percent), and for those paroled (none versus 5 percent).
The facility's percentages fell within 3 percentage points of the national figures for all other categories.
Figure 3: Nationality of those
leaving ICE detention
Which nationalities predominate? Last year in the United States, individuals
from Mexico comprised the largest number of those leaving ICE detention. Some 43.4
percent of all detainees recorded Mexico as their country of origin.
The Polk County Jail had a much smaller proportion of detainees from Mexico - 14 percent among their exits.
Detainees from Mexico were not the largest single nationality group among those leaving detention from the facility.
In descending order,
the top nationalities that made up those leaving ICE detention from the Polk County Jail last year were:
El Salvador (72%)
, Mexico (14%), Honduras (7%), Guatemala (7%) and Nicaragua (0%).
This compared to the United States as a whole where the other top five nationalities after
Mexico were Guatemala (19%), El Salvador (15%), Honduras (12%) and Ecuador (1%).
For the frequency for each of the other nationalities among those leaving ICE detention from the Polk County Jail last year see Table 4.
Deportations and voluntary departures by nationality.
Within the nationalities that made up those listed in Table 4 with more than one individual, the
proportion deported or voluntarily departing
varied from 0 percent to 98 percent.
As mentioned above, this compares with 95 percent for all detainees.

during the last 12 months
With the highest rate of 98 percent were detainees from El Salvador where 1,477 individuals were deported or took voluntary departure.
At the other end of the range were detainees from Nicaragua, where none ended up deported or were allowed voluntary departure.
