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, according to new estimates by the Pew Hispanic Center. 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. By region of origin, the population of unauthorized immigrants from Latin American countries other than Mexico has declined most markedly. By U.S. region, the decrease in the unauthorized immigrant population has been especially notable along the nation’s Southeast coast and in its Mountain West.

An estimated 340,000 of the 4.3 million babies born in the United States in 2008 were the offspring of unauthorized immigrants, according to a new analysis of Census Bureau data by the Pew Hispanic Center. Unauthorized immigrants comprise slightly more than 4% of the adult population of the U.S., but because they are relatively young and have high birthrates, their children make up a much larger share of both the newborn population (8%) and the child population (7% of those younger than age 18) in this country.
