About six-in-ten U.S. adults say abortion should be legal in all or most cases, while 37% say it should be illegal in all or most cases, according to a major new Pew Research Center survey, which was conducted March 7-13, 2022, among 10,441 adults.

The survey was fielded before the recent publication of a draft Supreme Court opinion that suggested the justices may be poised to strike down Roe v Wade, the landmark 1973 case that effectively authorized abortion nationwide.

While Republicans and Democrats have long been on opposite sides of the issue, the 42 percentage point partisan gap today is considerably larger than it was in the recent past. The change in attitudes has come almost entirely among Democrats: Currently, 80% of Democrats and Democratic-leaning independents say abortion should be legal in all or most cases, up from 72% in 2016 and 63% in 2007. Republicans’ views have shown far less change over time, with 38% of Republicans and GOP leaners saying abortion should be legal in all or most cases.
