The argument about deportation numbers is almost never an argument about arithmetic. It is an argument about which column somebody counted, conducted by people who have not said which column they counted. The government keeps four of them, on purpose, because they are four different things that happen to a person.
In 1954 the federal government carried out 30,260 removals and 1,074,280 enforcement returns. Both figures are true, both describe the same year, and they differ by a factor of thirty-five. That year is remembered as the largest deportation campaign in American history — and almost none of it was deportation in the legal sense.
A noncitizen is ordered out by an immigration judge or an authorised officer. It carries a bar on returning — typically five, ten or twenty years — and coming back before it expires is a federal crime. This is the column most people mean by "deportation", and it is the smallest of them for most of the last century.
A noncitizen is turned around without formal proceedings, historically at or near the border. No judge, no lasting bar, and until recently no record that follows the person. Table 39 splits these into administrative returns and enforcement returns. In 1954 there were 1,074,280 enforcement returns against 30,260 removals.
Title 42 of the US Code let border officials expel people to prevent the spread of communicable disease, and was used from March 2020 to May 2023. It is not an immigration proceeding at all, produces no immigration record, and a person could be expelled repeatedly in a week. It peaked at 1,103,970 in FY2022, which is more than every removal in that year by a factor of ten.
Immigration detention is civil, not criminal. It exists to secure a person for proceedings or removal, not to punish, which is why there is no fixed term and why the constitutional limits on how long it may last are still being argued. In FY2026 the average daily population was 64,508, of whom 26,843 had no criminal conviction and no pending charge.
A section of the 1996 immigration act that lets DHS deputize state and local officers to perform specified immigration functions under federal supervision. It ran at 135 agencies in December 2024 and 2,411 agreements by August 2026. It is the mechanism that turns a traffic stop into an immigration arrest.
