The CDC’s National Center for Health Statistics released a new report on Dec. 11 that found 18 percent of pregnancies in the U.S. in 2010 ended in abortion, while 17 percent ended in miscarriage and 65 percent resulted in birth.
Using numbers from the National Vital Statistics System, researchers from the CDC and the Guttmacher Institute found that abortions dropped by 35 percent from 1990-2010, notes CBS News.
"Across the states, the rate of unintended pregnancy is going down," co-author Kathryn Kost, principal research scientist at the Guttmacher Institute, told the news network. "That suggests that fewer women are getting pregnant when they don't want to. It's happening across the board, and affects the birth rate and the abortion rate."
“Much has been written about the birth rate, and much about the abortion rate, but a lot are shown separately,” Sally Curtin, the report's coauthor and a statistician with the National Center for Health Statistics, told TIME.

“If we put abortions in context, you can see that in a given year, the numbers of abortions, which is 1.1 million, is about the same as fetal loss,” Curtin added. “It used to be very different, if you look back; the number of abortions in 1976 was almost twice that.”
In a comparison to numbers from 1990, teens 14 and under had a 67 percent reduction in pregnancy rates, while teens ages 15-19 had a 50 percent drop. Women 30 years of age and older had a rise in birth rates, while those 40 and older had a 70 percent increase.
“The beauty of the report really is that it presents a comprehensive picture of fertility,” Curtin said.
