The Impact of Legal Abortion on Maternal Mortality
研究1969-1973年堕胎合法化如何影响孕产妇死亡率，发现合法化使非白人孕产妇死亡率降低30-50%，第一年就避免了134例死亡，且州级合法化比罗诉韦德案本身影响更大。
Legal abortion has recently been suggested as an essential health care service. In this study, we consider whether abortion legalization over 1969–1973 improved women’s health as measured by maternal mortality. Our event study results indicate that legal abortion substantially lowered non-White maternal mortality by 30–50 percent, with 134 non-White maternal deaths averted nationally in the first year abortion became legal. We also find that early state-level legalizations were crucial and more influential than the Roe v. Wade decision itself.
