https://www.kff.org/womens-health-policy/dashboard/abortion-in-the-u-s-dashboard/#releasesThis was used as a proxy for acceptability of abortion services in a given state, and an estimate of the climate/prior restrictions in the state before the Dobbs decision.
Two states (Missouri and North Dakota) had their legislature pass an abortion ban but it was blocked in court so they were currently labeled as “gestational limit at or near viability” in Dec 2024. Given this is a proxy for climate and a ban was passed, I considered them as abortion banned for this analysis.
