Wait, where are you getting those shades for CA and WI? The Wikipedia map indicates legal until viability (and the east coast viability states are ones you’ve shaded yellow). All the info I can find on those states suggests viability as the line as well.
Notice I labeled them "during 1st/2nd/any trimester." Wiki says the law is unclear for Wisconsin, and there are no providers in North Dakota, so both are gray.
Yeah - so why are Washington and California colored in differently from Maine, Connecticut, Hawaii, Maryland, and Michigan, who all also use the exact same “viability” line?
Also, it makes no sense to separate “viability” and “24 weeks” considering viability is generally considered to occur between 23 and 24 weeks - either all of them should count as second trimester or none of them should.
