It’s likely that many of the illegal immigrants have left:
Classrooms in Orange County, Calif., are suddenly half-empty. Latino day laborers seem to be less thick on the ground at their morning gathering places. Remittances to Mexico and other Latin countries are down, and men are returning to some villages from the United States.
Latinos appear to account for a disproportionate share of mortgage foreclosures. The Census Bureau estimates that net immigration in 2007-08 was 14 percent lower than the average for 2000-07, and those estimates don’t cover the period after June 30, when the recession really started hitting.
