PHILADELPHIA, July 10 (UPI) -- The U.S. birth rate dropped to a record low in 2011, but while young women put off babies, women giving birth in their 40s rose 1 percent, researchers say.
Gretchen Livingston, a senior researcher at the Pew Hispanic Center and the Pew Social & Demographic Trends Project, said the total number of births in 2011 -- 3,953,590 -- represented a 1 percent decline since 2010.
