Roe v. Wade guaranteed abortion as a legal right across the country. A separate decision two decades later, Planned Parenthood v. Casey, guaranteed states’ rights to limit access to abortion, so long as it did not pose an “undue burden” on the woman.
States have, over the past four decades, made no short use of that latter right. Only one state, Oregon, has not layered additional restrictions on top of the Roe decision. At the other end of the spectrum is Oklahoma: With 22 abortion restrictions, it has more than any other state. The chart below, courtesy of Remapping the Debate, has the full list. You can also go here for an interactive version of the graphic, which will let you look at what type of restrictions each state has set.
