 In a 2011 news story, the "Los Angeles Times" reported, ... illegal immigrants in 2010 were parents of 5.5 million children, 4.5 million of whom were born in the U.S. and are citizens.Because illegal immigrants are younger and more likely to be married, they represented a disproportionate share of births—8% of the babies born in the U.S. between March 2009 and March 2010 were to at least one illegal immigrant parent.Immigration from Mexico to the United States has slowed in recent years.
