Resolve according to the report published by Guttmacher Institute.
https://states.guttmacher.org/policies/

States which classified as "Restrictive", "Very Restrictive" or "Most Restrictive" counts as being restrictive on abortion for the Resolution of this market.

Currently 28 states are classified as "Restrictive", "Very Restrictive" or "Most Restrictive"

If Guttmacher Institute stop publishing the report, I will try to find another state level report on abortion to judge this question.
