U.S. Unauthorized Immigration Flows Are Down Sharply Since Mid-Decade
The annual inflow of unauthorized immigrants to the U.S. was nearly two-thirds smaller in the March 2007 to March 2009 period than it had been from March 2000 to March 2005. This decline contributed to an overall 8% reduction in the unauthorized immigrant population, which fell to 11.1 million in 2009 from 12 million in 2007. The decrease represents the first significant reversal in the growth of this population over the past two decades.
