NEW YORK — US abortions appear to be inching up after a long decline, though officials are cautious about calling it an upward trend because a government report issued Wednesday is incomplete.
National abortion figures in 2017 reached their lowest level since the 1973 U.S. Supreme Court decision that legalized abortions.
But the next two years, there were small increases in the abortion rate and numbers, the Centers for Disease Control and Prevention reported.
They rose 1% in 2018. The next year, the numbers increased 2% and the rate per 1,000 women of child-bearing age rose 1%.
The CDC report represents the latest available data on U.S. abortions. But it must be interpreted cautiously because it is based on voluntary reporting and is not comprehensive, experts say.
Among its limitations: It does not include abortions from three states — including California, the nation’s most populous state. Other states may have significant undercounts.
Those omissions mean that as much as 30% of the nation’s abortions may not be captured in the CDC data, according to officials at the Guttmacher Institute, a New York-based nonprofit research organization that supports abortion rights. The group conducts a more comprehensive survey of all U.S. abortion providers every three years, and its next report is due out next year.
Despite the CDC report’s limitations, it generally has painted a similar overall picture to what Guttmacher reports, said Rachel Jones, the lead researcher on that project.
“Historically, the trends tend to be the same,” Jones said.
U.S. births have been declining for more than a decade, meaning for years both births and abortions have been falling.
The idea that abortions may be increasing lately may be surprising, especially given recent efforts in many states to restrict abortions.
“If it means more people are getting access to care when they need it, than this is a positive development,” Jones said.
An increase could be related to access and use of birth control, and it may even be tied to whether more people are having sex, she said.
Overall, there were about 630,000 abortions reported to CDC in 2019. The abortion rate was 11.4 abortions per 1,000 women aged 15–44 years. That year, 56% of the reported abortions were surgical and about 44% were through use of the so-called abortion pill.
The report also showed about 18% of all pregnancies in the U.S. ended in abortion.
Jones noted that it is hard to make general statements about U.S. abortion trends, because there can be dramatic differences from one state to the next. And numbers in one state can increase if women are traveling there from other states.
It’s not yet clear what abortion trends will look like for 2020 during the COVID-19 pandemic. Some states — including Indiana, Iowa and Kansas — have reported increases. But it’s possible that abortions declined in many places during lockdowns, Jones said.
“Whatever happened in 2020 wasn’t just a matter of a long-term trend. It also was impacted by COVID,” she said.
