Monthly data collected by the Census Bureau show a significant drop in the
number of less-educated, young, Hispanic immigrants in the country. Prior
research indicates that more than three-fourths of these individuals are illegal
aliens. The fall in this population implies that the total illegal immigrant
population has declined almost 14 percent (1.7 million) from its peak in July
2007. In just the last year the decline between the first quarter of 2008 and
the first quarter of this year is almost 6 percent.
