most Americans (57%) are supportive of legal abortion

American religious groups vary widely in their views of abortion More than four decades after Roe v. Wade legalized abortion nationwide, most Americans (57%) are supportive of legal abortion, according to a 2017 Pew Research Center survey. But a substantial minority (40%) says abortion should be illegal in all or most cases, and within some U.S. denominations and religious groups, this figure is much higher.
