Eighty-two percent of U.S. Catholics say birth control is morally acceptable, nearing the 89% of all Americans and 90% of non-Catholics who agree. The level of acceptability on this issue is far greater than that of the other 17 issues Gallup asked about this year…

The issue of birth control tops the list of morally acceptable behavior across the 18 issues tested this year. At the bottom of the list is the issue of “married men and women having an affair,” which only 7% of Americans find morally acceptable. Having an affair has been at or near the bottom each year since Gallup began tracking these issues in 2001.
