Overview. Details on all Immigration and Customs Enforcement (ICE) apprehensions have been
compiled from arrest-by-arrest records obtained from Immigration and Customs Enforcement (ICE).
These records were obtained after successful court litigation by the co-directors of the Transactional
Records Access Clearinghouse (TRAC) at Syracuse University. The data are limited to what ICE refers to
as "interior arrests." According to ICE, these data do not include arrests made by Customs and Border
Protection (CBP) when the individual is transferred to ICE for detention and eventual removal.
The data available includes the state and county where each ICE arrest occurred. This was not obtained
from ICE as the agency contends it doesn't track the state or county where the apprehension occurred.
Painstaking research by TRAC using a mosaic of records obtained from a range of sources, including
those derived from hundreds of separate FOIA requests over the span of several years, has allowed
TRAC to independently identify the state and county where most arrests occurred. Sometimes the
county listed includes closely surrounding areas where it was not possible to further isolate the arrest
Coverage. Data for the first phase of TRAC's research on the location of ICE arrests covers each recorded
ICE arrest during the period October 2014 - October 2017. Work is continuing. This research initiative
to identify arrest locations has been made possible through research grants from the Carnegie
Corporation of New York and The Kresge Foundation. TRAC's goal is to steadily extend this information
series to the over 2 million past ICE arrests the Center has collected information on, while updating the
series as more ICE arrests occur and information can be compiled.
Using the Data Tool: Dimensions and Definitions
Filtering the data using the three data tables. Select a different factor or dimension to display
using the menu at the top of each of the three tables. The tables are inter-connected so that the
data filter from left to right. After selecting a factor to display in the left most table, select a
particular row category to drill in on by clicking on that row's label in the left-most table. The
middle table will then display the details for that particular selection from the left table on the
dimension you had chosen to display for the middle table. In other words, if you click on a
category in the left table it displays only cases within that class in the middle table. Click on a
category in the middle table to display only cases within that selection in the right table. To help
you keep track, your selection is displayed at the top of the table to the right.
Sorting the tabular data displayed. By clicking on the column headings in a table, you can sort
the tabular data displayed. Clicking on the table column heading for the name of the dimension,
sorts each tabular row in alphabetical order. Clicking a second time, sorts in reverse alphabetical
order. Clicking on the column heading "Total" reverses the default sort order of largest to
smallest to display from the smallest to the largest value.
Selecting what is displayed in the time series graph. The data in the graph updates to reflect
the category in the table you selected when clicking on its row label. The title shown above the
graph indicates the selection criteria you have chosen. Mouse-over any bar in the graph to view
the value being plotted.
There are also two additional controls you can use to change what the graph displays.
Monthly versus fiscal year radio buttons. By default, the time series graph displays data
for each month. To instead display bars for each fiscal year, choose the "by Fiscal Year"
option to the left of the graph.
Number/percent radio buttons. By default, the number of cases is displayed in the graph.
To instead display the value as a percent of the total for your current selection, choose the
"Percent" option to the right of the graph. (Note: 100 percent will be displayed if the total
("All") was the category you have currently selected.)
Data dimensions. To change the set of categories displayed in a table, select a different factor or
dimension from the pull-down menu above each table. The following factors can be selected:
Fiscal Year. This is always the fiscal year when ICE arrested the individual. The federal
government's fiscal year runs from October 1 to September 30. So, for example, FY 2017
will return cases from October 1, 2016 through September 30, 2017.
Month and Year. This is the calendar month and year when the individual was arrested by
State. The state in which the arrest took place.
County/Surrounding Area. The county in which the arrest took place. On occasion, the
county listed includes closely surrounding areas where it was not possible to further
isolate the arrest location.
Apprehension Method/Agency. Composite developed by TRAC from ICE records
identifies how ICE assumed custody ("custodial arrests") from another law enforcement
agency versus when the individual was located out in the community ("community or at-
large arrests") and was picked up directly by ICE. Custodial arrests usually occur as part
of the agency's
Criminal Alien Program (CAP)
which is conducted in cooperation with federal, state and local law enforcement
agencies. Sometimes it involves a special cooperative relationship with state or local law
enforcement agencies under a Memorandum of Agreement through
ICE's 287(g) program.
Community (At-Large) Arrest. ICE records indicate the individual was located living in
the community and arrested directly by ICE.
Immigration Violation Deportation Based. The formal legal grounds under immigration
statutes on which ICE alleges deportation was warranted. There are a myriad of rules
subjecting a person to deportation. These include simply being present in the country
without valid documents, entry without inspection, controlled substance violations,
willful misrepresentation of material facts, conviction of crimes involving moral
turpitude, and many others.
Removal Ordered. Whether a removal order has been entered or a previous removal
order has been reinstated. If the records indicate the order is an expedited removal order
that is also indicated. The fact that removal has been ordered does not imply that the
individual has been deported, or even that the removal order is final since there may be
Latest Status/Disposition. Indicates whether the case is still active or has been
completed. Completions include deportation as well as decisions that found the
individual was legally entitled to remain in the U.S.
Time in U.S. Length of time that available ICE information indicate the individual has
resided in the U.S. This information was not made available by ICE for a significant
number of individuals.
Entry Status. The category that ICE records individuals were placed in when they most
recently entered the country. Includes, for example, whether the individual was a legal
permanent resident, a non-immigrant, an immigrant, a visitor, was seeking asylum
(includes refugees), entered under the visa waiver program, was a parolee, or was present
without admission. This information is not recorded by ICE for a significant number of
Most Serious Criminal Conviction (MSCC). The recorded most serious offense the
individual was convicted for. Offense categories utilize the National Crime Information
Center (NCIC) coding system maintained by the Federal Bureau of Investigation. Where
there are multiple convictions, ICE identified the most serious offense. Note that ICE has
improved it methods for recording criminal convictions so that data for earlier years may
be less comprehensive.
Seriousness Level of MSCC Conviction. ICE classifies National Crime Information
Center (NCIC) offense codes into three seriousness levels. The most serious (Level 1)
covers what ICE considers to be "aggravated felonies." Level 2 offenses cover other
felonies, while Level 3 offenses are misdemeanors, including petty and other minor
violations of the law. TRAC uses ICE's "business rules" to group recorded NCIC offense
codes into these three seriousness levels.
Age Group. The age of the individual at the time of the arrest. ICE is currently
withholding this information and TRAC is disputing this withholding as unlawful.
Citizenship. The recorded citizenship of the individual.
Gender. The recorded gender of the individual.
