Gallup's latest update on U.S. abortion attitudes finds 58% of Americans opposed to overturning the U.S. Supreme Court's 1973 Roe v. Wade decision, while 32% are in favor. Since 1989, between 52% and 66% of U.S. adults have wanted to maintain the landmark abortion decision. Today's support roughly matches the average over that three-decade period... Fifty-six percent are opposed to banning abortions after the 18th week of pregnancy, a threshold used in laws passed in two states (Arkansas and Utah), although both laws are currently blocked by court orders. Fifty-eight percent oppose banning abortions once the heartbeat of a fetus can be detected -- an abortion restriction passed in several Republican-led states, all of which face court challenges. A fetal heartbeat can typically be detected between six and eight weeks into a pregnancy. While that time frame wasn't specified in the latest Gallup measure, it was in a 2019 question, with similar results.
