Americans with no religious attachment (self-identified atheists, agnostics, and those with simply no religious preference) identify as pro-choice by a 49-percentage-point margin over pro-life, 68% to 19%. This represents the strongest propensity toward the pro-choice position of any major U.S. demographic (as distinct from political) subgroup. This group is also more heavily pro-choice than Democrats, but its views are similar to those of political “liberals,” 74% of whom are pro-choice and 19% pro-life.
In contrast to Americans with no religious affiliation, majorities of those who identify with either of the two major U.S. Christian faiths call themselves pro-life: 54% of all Catholics and 57% of Protestants. The sample size of those who identify with a non-Christian religion is too small to allow meaningful interpretation.
The gap in abortion views by education is not as wide as that seen between Christians and non-Christians, but is still stark.
