WASHINGTON (Reuters) - The pregnancy rate among U.S. women fell to its lowest point in 12 years in 2009, continuing its slide from a peak in 1990, according to U.S. government data released on Thursday.
While rates for women aged 30 and younger fell between 1990 and 2009, with a notable decline among teenagers, they increased for those aged 30 and older, the Centers for Disease Control and Prevention said.
The rate was 102.1 pregnancies for every 1,000 women in 2009, the most recent data researchers analyzed. That is the lowest since 1997, when the rate was 101.6 per 1,000 women, a report by the CDC's National Center for Health Statistics said.
"After a brief increase in 2006 and 2007, the ongoing declines in the number and rate of pregnancies continued," the report said.
A variety of social and economic factors affect the nation's reproductive rates, researchers said. "It has been suggested that the declining economy, beginning in 2007, has likely played a role in the decreased rates for women under age 40," they added.
Teen rates were also historically low, the report found.
Researchers analyzed three data sets, including information from one of CDC's ongoing national surveys. That survey found that fewer teens say they are sexually active and that those who do have sex say they are more likely to use contraception.
The pregnancy rate does not directly correlate with the nation's birth rate.
Of the estimated 6.4 million pregnancies in 2009, more than 4.1 million resulted in live births and about 1 million deaths, the CDC said. There were also nearly 1.2 million abortions.
A separate CDC report, also released on Thursday, showed U.S. births for the year ended in June 2013 at about 3.9 million, a decline from 2007, when the number reached a historic high of more than 4.3 million.
Researchers said they needed more current data on the nation's abortion rate to see whether pregnancy rates have also leveled off.
