ImmigrationClock explains · Enforcement data
Arrests, removals and detention are three different numbers
One arrest is not one deportation, and neither is a headcount in custody.
The facts
- An ICE arrest is an administrative arrest: the agency takes someone into custody. A removal, as ICE reports it, is a confirmed departure from the country; the figure mostly reflects orders of removal but also includes some voluntary returns and departures made without one. The detained population is the number of people in ICE custody at a point in time, published in ICE's detention statistics.
- Arrests and removals are cumulative counts over a fiscal year. The detained population is a snapshot of one day, and a snapshot does not stay true the way a year-end total does.
- The three measures have different denominators and cannot be added together. Someone arrested in one year may be removed in another, or not at all.
- ImmigrationClock labels each figure by which of the three it is and how complete its period is, and shows the detention figure with the date it was taken.
Why it matters
"ICE deported X people" is usually a sentence about arrests, removals or detention, and which one changes the meaning entirely. The label is the fact.
