Fewer Americans say birth control, having a baby outside of marriage, and gambling are morally acceptable than did a year ago, according to a new Gallup poll that points to a possible shift toward more traditional values.

The findings came amid a Republican political resurgence, renewed religious interest among younger Americans — particularly young men — and growing resistance to progressive social policies.

While majorities still view birth control, out-of-wedlock births, and gambling as morally acceptable, support for each has declined significantly from 2024 levels.

Gallup found that 83% of Americans now consider birth control morally acceptable, down from 90% last year and the lowest level recorded since the polling organization began tracking the issue in 2012.

Attitudes toward having a baby outside of marriage also have changed. After reaching 70% in both 2022 and 2023, the share of Americans who say it is morally acceptable has fallen to 58%.

Megan Brenan, a senior editor at Gallup, told Axios that much of the movement on issues such as birth control and out-of-wedlock childbirth came from political independents.

The results could signal a shift away from more liberal social attitudes, Brenan said. The numbers could reflect a pendulum swinging back toward the center, or, "maybe it is a real beginning of something."

The survey also found declining acceptance of gambling, which reached a new low in Gallup's trend data.

The drop comes as prediction markets have emerged as a popular — and often controversial — way to wager on political races, sports, business developments and other current events. Earlier research from Ipsos and the American Institute for Boys and Men found Americans generally view prediction market trading more as gambling than investing.

Across the issues Gallup measured, majorities of Americans said eight practices are morally wrong: sex between teenagers, extramarital affairs, human cloning, polygamy, suicide, animal cloning, pornography, and changing one's gender.

The decline in the share of Americans who view changing one's gender as morally acceptable coincides with waning support for same-sex marriage and for the morality of gay and lesbian relationships.

The survey revealed sharp partisan differences on several issues.

Democrats were far more likely than Republicans to say abortion and changing one's gender are morally acceptable. Republicans, meanwhile, were considerably more likely to support the death penalty, wearing clothing made from animal fur, and medical testing on animals.

Some issues drew bipartisan opposition. Republicans and Democrats gave poor marks to human cloning and animal cloning.

The poll was conducted May 1-17 and surveyed 1,001 U.S. adults. It has a margin of error of 4 percentage points.
