In a YouGov analysis of polling data on abortion from the past year, atheists are the most likely to identify as pro-choice, at 91%, among groups defined by their religious faith or attitude toward religion. Agnostics come in next, with 83% who say they are pro-choice. Just over three-quarters (77%) of Jewish people say they’re pro-choice, along with 76% of Buddhists.
Most people (63%) who say their religion is “nothing in particular” also take a pro-choice stance, followed by 56% of Muslims.
Roman Catholics, whose religion forbids abortion, are nearly evenly split, with 46% identifying as pro-choice and 47% as pro-life.
