Some of Trump’s first actions in office were two executive orders meant to crack down on illegal immigration by implementing tougher enforcement not just at the border but also within the country. This week The Washington Post reported that U.S. Immigration and Customs Enforcement had arrested 21,362 unauthorized immigrants across the country since Trump took office, a 32.6 percent increase from the previous year. (The data runs through mid-March.) At first glance these numbers might seem consistent with Trump’s promise to get “the bad ones” out of the country. But the Post also noted that of those arrested roughly a quarter, or 5,441, had no criminal record. That’s more than double the number of noncriminal arrests of undocumented immigrants during the same period in 2016. (Many of those arrested eventually will be deported, but because that process can be slow, changed enforcement patterns show up more quickly in arrest data.)
Look back a bit further, however, and the recent increase in enforcement looks less dramatic. The pace of arrests is running well behind the 29,238 made during the same period in 2014; that year, there were 7,483 noncriminal arrests through mid-March, which represented a similar share of the total as this year’s numbers.
That is from Ben Casselman, et.al. at 538.
