| # 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.** |
