Nearly two-thirds of the 10.2 million unauthorized adult immigrants in the United States have lived in this country for at least 10 years and nearly half are parents of minor children.
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.
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.
Hispanics now make up 22% of all children under the age of 18 in the United States–up from 9% in 1980–and as their numbers have grown, their demographic profile has changed.
There were 11.9 million unauthorized immigrants living in the United States in March 2008. The size of the unauthorized population appears to have declined since 2007.
