WASHINGTON, April 8 (UPI) -- More women in the United States have no children now than at any other time since the U.S. Census Bureau began keeping records in 1976.
An average of nearly half, 47.6 percent, of women between the ages of 15 and 44 did not have children in 2014, up from 46.5 percent in 2012, according to the Census Bureau. The average of women without children between the ages of 15 to 44 in 1976 was 35.1 percent.
The general fertility rate in the United States fell for its sixth straight year in 2013. It stands at 1.86, according to The New York Times. A fertility rate of 2.1 is required to have a stable U.S. population.
The decline in the fertility rate is more notable because the number of women in the prime childbearing years of 20 to 39 has continued to grow since 2007.
"Americans haven't worried much about birthrates in the past, because we have the faucet of immigration to turn on and off," Andrew J. Cherlin, a family demographer at Johns Hopkins University told the Times. "It's a bigger problem in Europe, where countries like Germany and Spain have much lower rates. And even at 1.8, we're in the ballpark with the highest rates in Europe."
Percent of women without children, per age group, in 2014:
15-19 years, 95.9 percent 20-24 years, 75.2 percent 25-29 years, 49.6 percent 30-34 years, 28.9 percent 35-39 years, 18.5 percent 40-44 years, 15.3 percent 45-50 years, 16.7 percent
