A report from Homeland Security that estimates the size of the unauthorized immigrant population residing in the U.S. in January 2010 shows 10.8 million – the same as in January 2009 – but down from 11.8 in January 2007.
Between 2000 and 2010 the unauthorized population grew by 27 percent. Of all unauthorized immigrants living in the U.S. in 2010, 39 percent entered in 2000 or later, and 62 percent were from Mexico.
California remained the leading state of residence of the unauthorized immigrant population in 2010, with 2.6 million followed by Texas and Florida. 63 percent were ages 25 to 44 years and 57 percent were male.
