A new Pew Research Center report concludes that the decline in birth rates and number of births from 2007 to 2010 was led by immigrant women. Overall birth rates declined 8% during this period, but birth rates for immigrant women plunged 14%. Overall numbers of births declined 7% from 2007 to 2010, but births to immigrant mothers fell by 13%. Despite these decreases, foreign-born mothers still account for a disproportionate share of births–23% in 2010, greater than the 17% share of women of childbearing age who are immigrants.
