evidence: Abstract - Issue: In response to the U.S. Supreme Court’s overturning of Roe v. Wade, a number of states have passed, or are planning to pass, partial or complete bans on abortion. A key question is whether these restrictions will result in reduced overall access to maternal and infant care, as well as worse health outcomes, in these states. [...] - Key Findings and Conclusions: Compared to states where abortion is accessible, states that have banned, are planning to ban, or have otherwise restricted abortion have fewer maternity care providers; more maternity care "deserts"; higher rates of maternal mortality and infant death, especially among women of color; higher overall death rates for women of reproductive age; and greater racial inequities across their health care systems. [...] The 26 states with abortion bans or restrictions (Exhibit 1) had slightly more than half (55%) of U.S. births in 2020. These states differed demographically from states with abortion access, as shown in Exhibit 2, with larger proportions of births to non-Hispanic white mothers. Abortion-access states, meanwhile, had a majority of births to women of color.
