Immigration and Customs Enforcement

Data processed and/or compiled by the Deportation Data Project

ICE collects data on every person it encounters, arrests, detains, transports via flight, and deports, and every detainer request to local jails.

We post lightly processed versions of the arrests, detainer requests, and detentions datasets to facilitate analysis. We also post a more heavily processed version of the detention data, collapsed to the detention stay level, to make analysis more straightforward. In addition, we post data we compiled from ICE sources on ICE detention facilities and field offices.

TipGetting started with ICE data

Our ICE frequently asked data questions is a good place to start before analyzing the data. Our codebooks describe the tables, fields, and processing steps for each dataset: core data (arrests, detainers, detentions, encounters, and removals), detention facilities, facility daily populations, and field offices and areas of responsibility.

We recommend citing these data as “government data provided by ICE in response to a FOIA request, processed by the Deportation Data Project, and analyzed by [your organization].”

Latest enforcement data release

The most recent release of data covers ICE enforcement actions through early March 2026. We are actively seeking ongoing updates.

We recommend using the detention stays dataset for most detention analyses at the individual level. For analyses at the detention facility level, by contrast, we recommend using the detention stints dataset. Note that filtering by stint can lead to inaccurate individual-level inferences, since a single person may appear across multiple stints when transferred between facilities.

Code and notes on how we processed the data are available in the ICE core data codebook.

We have several concerns about this new dataset.

First, and most important, we continue to have questions about the reliability of the encounters and removals data. These encounters and removals datasets are similar to the October versions but different from the late July release that we believe was most reliable. A comparison of the October and late July removals datasets is available here.

Second, in this version of the dataset, ICE omitted detention stints in hospitals and medical centers. This affects a small number of stints relative to the total—and therefore should not prevent analysis of the detention data—but it makes analysis of hospital stints impossible.

Third, ICE has redacted the “case_category” values for some individuals; comparing this release to previous releases suggests that these are mostly individuals who had credible fear interviews. For some of the individuals, ICE has also redacted detention release reasons (in the detentions table) and processing disposition values (in the encounters and removals tables). To obtain some of this missing information, we suggest joining the detention and removals tables to determine which individuals were booked out to be removed.

Detention facilities

We provide data on facilities in which ICE civil immigration detainees are held, including their locations and the ICE field offices with responsibility for the areas in which they are located. These include both facilities dedicated to immigration detention and others where noncitizens are briefly held, such as hospitals.1 The data on facilities were collated from multiple ICE sources, including ICE’s web site and FOIA requests to ICE by several organizations (see source details). Every one was manually verified by multiple coders.

We include facilities that held at least one detainee from January 1, 2025 through March 10, 2026. We plan to update the dataset when new facility openings are disclosed by ICE. We also plan to expand the data over time to include facilities that held detainees before January 1, 2025, and to add additional information about each facility.

We include the state for all facilities, but only include more detailed location information for those we were able to locate with confidence. We do not provide locations for 133 ICE hold rooms we could not verify, listed below.

If you have documentation for any of these locations or corrections to others, we would love your help. Please email deportation_data_questions@law.berkeley.edu.

Field offices and areas of responsibility

We provide data on ICE field offices and their areas of responsibility (AOR) principally derived from ICE’s web site for use in conjunction with the individual-level enforcement data available above.

  • ICE field offices for each subagency: Field offices for all ICE subagencies. The Enforcement and Removal Operations (ERO) field offices hold primary responsibility for the majority of ICE arrests and its detentions and removals of noncitizens. Each field office has a defined geographic area of responsibility.
  • ICE ERO check-in offices (sub-offices): The offices where noncitizens may be required to report periodically. These are sometimes known as the sub-offices of the ICE ERO field offices.
  • ICE areas of responsibility (AORs): Geographic region managed by each ICE ERO field office. The areas of responsibility for other sub-agencies, such as Homeland Security Investigations, differ, and we do not include them here.

Footnotes

  1. Civil immigration detainees are also held at CBP facilities, generally excluded in these data, and unaccompanied minors are held after brief stays in ICE detention by the Office of Refugee Resettlement (ORR) of the Department of Health and Human Services. Those ORR facilities are also excluded here.↩︎
