# CBP Border Enforcement Database
Individual-level Customs and Border Protection records obtained by the Deportation
Data Project through FOIA litigation: Border Patrol apprehensions (FY2008-Dec 2025),
apprehensions with place of birth (FY2000-FY2022), encounters, Office of Field
Operations inadmissibility events at ports of entry (CY2014-Jan 2026), Title 42
expulsions and CBP One appointments. 121 release files harmonised into one schema
per record type; overlapping release windows resolved into a non-overlapping base
tiling (see `_files`).
**51,345,742 rows across 8 tables.**
