Researchers at the National Center for Health Statistics and the Centers for Disease Control and Prevention, both federal agencies, have released new data confirming that the number of babies born to teenaged mothers has dropped by 6 percentage points to 29.4 births per thousand in 2012–the lowest number since the agencies started collecting this data 73 years ago. The decline was across all racial and ethnic groups, and analysts attribute much of the drop to more women using effective birth control methods. More from NBC News:
The 2012 number is “a considerable one year drop,” says pediatrician Dr. John Santelli, a professor of population and family health at Columbia University who has no connection to the study. And it follows fairly sizable declines since 2007, when the rate was 41.5 births per thousand young women ages 15 to 19. In fact, except for a small uptick between 2005 and 2007, the teen birth rate has been steadily declining since 1991, when it reached 61.8 births per thousand.
“Our data comes from the birth certificate that parents complete at the hospital and it provides a wealth of information,” says Brady E. Hamilton, a statistician with the National Center for Health Statistics and the lead author of the report. But to figure out why the teen birth rate is falling, “we have to rely on other sources,” Hamilton says, such as surveys that the CDC conducts of high schoolers.
Santelli has studied those and other survey results. “There is not much evidence of a change in abortion use and not much change in sexual activity” since 2003, says Santelli. For example, the percentage of high school kids reporting ever having sexual intercourse was about 54 percent in 1991, according to the CDC survey, declined through 2002, and then held steady at about 47 percent through 2011, the last year of available data.
“What we have seen is greater availability of much more effective birth control methods,” says Santelli. While condom use increased substantially in the 1990s and early 2000s among high schoolers, it actually declined slightly after that, according to the CDC survey. At the same time, medical professionals have increasingly been recommending the IUD, a small, plastic device that is inserted and left inside the uterus to prevent pregnancy, says Santelli. While it does not protect against sexually transmitted diseases, it can be used in combination with a condom, which does offer such protection.
“Young people sometimes use condoms incorrectly, and sometimes they forget to use condoms,” says Santelli. “There is almost zero user error with the IUD. Once it is in place, it works every time.”

Teen birth rates have been declining steadily in recent years, but they now have shown marked declines in virtually every U.S. state, especially in the Mountain states and especially among the Hispanic population, according to a new government report. More from The Associated Press:
All states but West Virginia and North Dakota showed significant drops over five years. But the Mountain States of Arizona, Colorado, Idaho, Nevada and Utah saw rates fall by 30 percent or more.
In 22 states, teen Hispanic birth rates plunged at least 40 percent, which was described as “just amazing,” by the report’s lead author, Brady Hamilton of the Centers for Disease Control and Prevention.
What’s driving the declines? No one can say for sure. Experts believe the explanation is complicated and probably varies a bit from state to state. The national figure has been falling since 1991, aside from a brief interruption in 2006 and 2007.
The CDC report released Thursday is based on birth certificates for 2007 through 2011. Last year, the CDC announced the overall improvement in teen births: a record low of 31 births per 1,000 teens ages 15 to 19. That compares with 42 births per 1,000 five years earlier.

Following the trend of recent years and decades, the number of babies born to teenaged mothers fell radically, dropping 8 percent between 2010 and 2011 alone, according to data from the National Center for Health Statistics published in the journal Pediatrics. The rate has dropped 25 percent since 2007, and 49 percent since 1991. More from NBC News:
“There is lots of good news in the report,” said Brady Hamilton, a statistician at the NCHS who led the study.
It’s good news because such births are almost always unplanned and the parents are rarely ready to cope with the responsibility of raising a baby. Teenaged moms are also more likely to have babies of a smaller-than-healthy weight or to have stillborn babies.
The study looks at numbers alone and doesn’t address changes in teen behavior. But other research suggests that teens are more easily able to get birth control, says Laura Lindberg, a senior researcher at the Guttmacher Institute.
“If anyone tells you they know exactly why this has happened, they are lying,” Lindberg said in a telephone interview. “We don’t have all the research and behavioral data in place up to 2011.”
That said, there are more than a few hints, according to Lindberg.
“We have gone from a social norm where you don’t use contraception at first sex to where you do,” she said. “Lots of study shows that using contraception at first sex begins a pattern of using it down the road.”
Other statistics show that teenage sex is only down slightly, although girls and boys both are having sex later in their teens. “In contrast, there is an increase in contraceptive use, particularly hormonal methods,” Lindberg said.
