Brookings notes that starting in the late 2000s there was significant increase of annual deportations, to the level of about 400,000, which then subsided. Neither Obama supporters nor Republicans wanted to note that deportations rose under Obama. (Also go here). Trump has said he will undertake massive deportations of unauthorized residents. (The other day, the Biden administration said it will, in effect, deport some 500,000 humanitarian parole residents when their two years’ stay is up (go here.)

Brookings notes the effect of massive deportation. It does not provide a comprehensive assessment; instead, focuses on a few sectors, and then rather shallowly:

“When construction companies have a sudden reduction in available laborers, they must reduce the number of construction site managers they hire. Similarly, local restaurants need cooks to stay open and hire for other positions like waiters, which are more likely to be filled by U.S.-born workers. Caregiving and household service jobs are also common among unauthorized immigrants. The availability and cost of these services in the private market greatly impacts whether people can work outside the home. “
