Geography of Abortion Law

Abortion never legal, or legal only when necessary to save the life of the mother or protect her physical health.

Abortion legal in "hard cases", such as rape, incest, and/or deformed child.

Abortion legal for social reasons (e.g. mother says she can't afford a child), or to protect the mother's "mental health" (definitions and requirements vary).

Abortion legal at any time during pregnancy for any reason.

I cannot attest to the accuracy of the plot. For example, although the U.S. is colored purple, my understanding is that at least some states have some restriction on third-trimester abortion. But maybe that's no longer true.

Anyway, the plot is interesting.
