Research Tools: “Tracking Over 2 Million ICE Arrests: A First Look”

From the Transactional Records Clearinghouse (TRAC)/Syracuse  University):

The latest data on each ICE arrest for the first time now allows the public to track in some detail over 2 million ICE arrests from October 2008 through June 2018. These are what ICE refers to as arrests that occur in the interior of the country, and exclude arrests by Customs and Border Protection (CBP). This report focuses on the source of each of these ICE arrests and how the volume of this activity—along with the way ICE takes individuals into custody—has changed over the past decade.

Simultaneously released with this report is the first edition of TRAC’s “ICE Arrests” app. The data available covering October 2014 – October 2017 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.


This research identifying arrest locations has been made possible through 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.

This free online query tool allows users to examine ICE arrest activity along 15 separate dimensions. In addition to when and where each arrest occurred, information has been compiled providing details on how the arrest occurred. These details are combined with the characteristics of the individuals who were targeted, as well as the immigration violation they were charged with. For cases that ICE has closed, the final outcome recorded by ICE for each individual is also tracked.
