The number of abortions provided in most of the U.S. increased slightly in 2024 from the year before, according to new data released on April 15.

The research was conducted by the Guttmacher Institute, which studies and supports sexual and reproductive health and rights. The organization uses both a statistical model and survey responses from providers to estimate the number of abortions provided by clinicians in states without near-total bans for its Monthly Abortion Provision Study. The data released on April 15 show that nearly 1,038,100 abortions were provided in 2024 across all states without near-total bans—a less than 1% increase from 2023 to 2024.

While that number is relatively steady compared to the year before, researchers noted that the finding “masked substantial variability across individual states,” with some states experiencing significant decreases and others seeing notable increases. For instance, there were roughly 12,100 fewer abortions provided in Florida in 2024 than in 2023, which researchers attributed to the state implementing a ban on abortion after six weeks of pregnancy, a policy that went into effect in May 2024. Similarly, South Carolina provided about 3,500 fewer abortions in 2024 than in 2023. Researchers attributed this to the state’s six-week ban, which was upheld by the state Supreme Court in August 2023.

At the same time, researchers found that the number of abortions provided in Wisconsin increased from about 1,300 in 2023 to about 6,100 in 2024—an increase of 388%. Abortion access in the state became largely unavailable after the U.S. Supreme Court overturned Roe v. Wade in 2022 until late 2023, when a Wisconsin judge ruled that an 1849 law that had been interpreted as a ban didn’t make abortion illegal. Arizona, California, Kansas, Ohio, and Virginia also saw significant increases in the number of abortions provided in 2024 compared to the year before.
