U.S. Birth Rate Falls to a Record Low; Decline Is Greatest Among Immigrants, by Gretchen Livingston and D’Vera Cohn. November 30, 2012

• “The U.S. birth rate dipped in 2011 to the lowest ever recorded, led by a plunge in births to immigrant women since the onset of the Great Recession.
• The overall U.S. birth rate, which is the annual number of births per 1,000 women in the prime childbearing ages of 15 to 44, declined 8% from 2007 to 2010. The birth rate for U.S.-born women decreased 6% during these years, but the birth rate for foreign-born women plunged 14%—more than it had declined over the entire 1990-2007 period. The birth rate for Mexican immigrant women fell even more, by 23%.”
