from the Washington Post is this 2013 article by Sarah Kliff.
...Through the mid-1960s, 44 states outlawed abortion in nearly all situations that did not threaten the life or health of the mother. States began liberalizing their abortion laws in the 1960s and 1970s. This map shows the situation in the early-1970s, when Roe was decided.
The four maroon states legalized abortion in nearly all cases before the fetus was viable. The 14 pink states allowed abortions in some circumstances. Nearly all others continued to ban abortion in most cases.
This source lists the reformed group as : Colorado, North Carolina, California, Georgia, Maryland, Arkansas, New Mexico, Kansas, Oregon, Delaware, South Carolina, Virginia and Florida. I only count 13 which is also the count on the map.The part I bolded hollows out the headline. So, the subhead should read "1. Before the Roe decision, most states DID allow legal abortion." And the map should look different.
Note that unlike Kliff I include both a map showing an accurate representation of the subhead and also a map detailing what abortion laws actually looked like.
