Voters in six states have approved measures to protect or expand abortion rights, but a bid to restore protections for the procedure failed in Florida.
A variety of questions on abortion access were on the ballot in 10 states during the seismic election, in which the issue was a galvanising force for many voters.
The proposal in Florida would have allowed abortion until the point of foetal viability or about 24 weeks, but it fell short of the threshold of 60% support in order to pass.
But an amendment aimed at overturning a near-total abortion ban in Missouri, where a majority of voters backed Donald Trump, appeared on track for victory.
