Infant mortality has risen in states that enacted tighter abortion restrictions in the wake of the June 2022 Dobbs v. Jackson Women’s Health decision. In other words, our data showed that despite such exceptions, infant deaths increased at the same rate as states without the exceptions. Since that time, legislators in more than 20 states have instituted abortion restrictions that would not have been permissible under the previous Roe v. Wade standard. The same pattern holds nationally in states that enacted abortion restrictions in the wake of Roe being overturned. This murkiness deepens the mystery around how, exactly, abortion restrictions are putting infants at risk.
