Monthly Census Bureau data show that the number of less-educated young Hispanic immigrants in the country has declined significantly. The evidence indicates that the illegal population declined after July 2007 and then rebounded somewhat in the summer of 2008 before resuming its decline in the fall of 2008 and into the first quarter of 2009. Both increased immigration enforcement and the recession seem to explain this decline. There is evidence that the decline was caused by both fewer illegal immigrants coming and an increase in the number returning home. However, this pattern does not apply to the legal immigrant population, which has not fallen significantly.
