Thursday, Jan. 22 marks the 36th anniversary of the U.S. Supreme Court’s landmark abortion ruling, Roe v. Wade (1973). Abortion remains a divisive issue in the U.S., with a slim majority (53%) in favor of keeping it legal in all or most cases and four-in-ten in favor of making it illegal in all or most cases. However, the U.S. Religious Landscape Survey, conducted in 2007 by the Pew Research Center’s Forum on Religion & Public Life, finds that most religious traditions in the U.S. come down firmly on one side or the other. Religious beliefs and practices also influence views on abortion; individuals exhibiting high levels of religious commitment are much more likely to oppose legalized abortion in all or most cases than those who are less-observant.
