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%.
