20-year historical data from the Department of Homeland Security Statistics shows Customs and Border Protection (CBP) "encounters" by the Border Patrol and Office of Field Operations. 

CBP Encounters include any encounter with a removable noncitizen. This includes three sets of data:

(1) People who unlawfully crossed the border between ports of entry.
(2) People who entered at a port of entry but are inadmissible.
(3) People expelled under the Title 42 public health order between March 2020 and May 2023 due to COVID-19
