Data repository
This page collects and reposts individual-level Immigration and Customs Enforcement (ICE), Customs and Border Patrol (CBP), and Justice Department Executive Office of Immigration Review (EOIR) datasets. In most cases, these datasets are also available for download elsewhere. The original source is always a government agency (ICE, CBP or EOIR), but where other third parties have posted the data before we have, we link to their sites as the source.
Immigration and Customs Enforcement
(with Unique Identifiers)
ICE collects data on every person it encounters, arrests, detains, and deports. This section includes the datasets for which ICE has provided unique identifiers that correspond to individuals, allowing them to be followed anonymously through the stages of the enforcement process.
Arrests
This dataset shows only the date and method of every arrest (apprehension). Although the dataset is sparse, it may provide useful information when linked with detention and deportation data.
Show datasets
Risk classification assessments
This dataset shows information on each risk classification assessment (RCA)–the procedure used by ICE to determine danger and flight risk. Note that the RCA tool is used both to help ICE officers decide whether to detain or release a person and to determine risk levels for detention (see the rca_decision_type field).
Show datasets
Detentions
This dataset includes a row for every detention book-in/book-out. Notice that a single stay in detention—defined by a stay book-in and stay book-out date—may include multiple rows because ICE frequently transfers people between detention centers.
Show datasets
Removals (deportations)
This dataset includes a row for every removal (deportation) that ICE conducted. Note that individuals can be returned or expelled by CBP at the border without appearing in this dataset.

Immigration and Customs Enforcement
(without Unique Identifiers)
This section includes other, unlinked ICE datasets. Many of these overlap with the linked data available for download above.
Arrests
These datasets include details on arrests (apprehensions). There are many more fields in these data than the above dataset on arrests, but these data do not include the linked identifier so can only be used on their own.
Show datasets
Detainers
Detainers are requests that ICE makes to prisons and jails to hold individuals for transfer to immigration custody and/or to notify ICE of their release dates. This dataset tracks each detainer request and its outcome. For some years there are two versions of the data, one that has many fields and on that has few fields but includes the city and state of the detention facility which is missing from the expanded data.

Detention facilities
This file includes some (out-of-date) information on ICE detention facilities.
Show datasets
Encounters
This dataset records each encounter that an ICE officer had with someone, whether or not that encounter resulted in an arrest.
Show datasets
Flights
Data on ICE-operated charter flights and passenger manifests from the Immigration and Customs Enforcement’s ARTS system.
Show datasets
Removals
This dataset includes a row for every removal (deportation) that ICE conducted. Note that individuals can be returned or expelled by CBP at the border without appearing in this dataset. These data have more limited fields than the linked data above.

Customs and Border Protection
CBP collects individual-level data on every person it arrests or expels at the border as well as on every person who arrives at a port of entry whom it deems inadmissible (most frequently asylum seekers). Border arrest data are collected by the Border Patrol; inadmissible arrivals data are collected by the Office of Field Operations. CBP maintains a detailed FOIA library with these datasets and others.
Apprehensions at the border
This dataset includes every apprehension at the border. Before 2020, all border arrests were apprehensions, and these files therefore include all arrests for those years. With the onset of the Title 42 pandemic expulsions program, some border arrests led to expulsions, which CBP does not categorize as apprehensions.
Show datasets
People deemed inadmissable at ports of entry
This dataset includes records of each person CBP found inadmissible at a port of entry. These are mostly asylum seekers.
Show datasets
Title 42 expulsions
This dataset includes Title 42 expulsions: the border arrests that CBP does not categorize as apprehensions.
Show datasets
Encounters
This dataset includes all border arrests, both apprehensions and Title 42 expulsions. Notice, however, that it exists currently only for a relatively short period.
Show datasets
Annual apprehensions with place of origin
This dataset includes each person’s city and state of origin, but it lacks precise dates for each apprehension (it shows only the fiscal year), limiting its use. The file names suggest that these files only contain family apprehensions, but they actually contain all apprehensions.
Show datasets
Executive Office for Immigration Review
(Immigration Courts)
The Executive Office for Immigration Review at the Department of Justice collects information on every immigration court case, including information on scheduling, case type, immigration charges, applications for relief, and appeals. The datasets includes records from the 1970s to the last year, though most are much more recent. The agency posts an updated dataset monthly in their FOIA Library, because of a FOIA request originally filed by TRAC.
