Catholic drinking in America falls to a record low as views on moderate drinking change

American drinking habits are undergoing a historic shift, with alcohol consumption among Catholic adults falling to record lows. According to a Gallup report, 55 percent of Catholic adults in the United States now say they drink alcohol.

The report, authored by analyst Frank Newport, says that in the 2002–2004 period the figure among Catholics was 79 percent. Over the same timeframe, self-reported drinking among Protestants has remained flat at 54 percent.

Historically, Catholics were far more likely to drink than Protestants. The sharp fall among Catholics has now completely eliminated that long-standing gap — the two groups' rates are now almost equal.

Newport wrote in the analysis that drinking has dropped significantly both among those with no religious identity and, in particular, among Catholics. Experts, however, urged caution in drawing sweeping conclusions from subgroup survey data.

Dr Joshua Gowin, an associate professor in the Department of Radiology at the University of Colorado Anschutz Medical Campus who studies alcohol's effects on the brain, noted that self-reported polling figures can fluctuate based on sampling.

Gowin said there is definitely a general pattern of alcohol use decreasing across groups. As for the subgroups, it was not clear or necessarily compelling to him that one group was showing a broad trend not reflected in others. In his words, really only one data point showed that effect, which made him a little skeptical that this is a broader phenomenon rather than a single survey sample.

Despite those methodological limits, researchers agree broader social and health trends are driving the shift in overall drinking habits. Gallup findings indicate a majority of Americans now view moderate drinking — one or two drinks per day — as bad for their health.

In the latest polling, 52 percent of Catholics said moderate drinking is bad for health, alongside 56 percent of adults with no religious affiliation and 48 percent of Protestants. The change in perception is visible across all religious demographics.

Gowin noted this public shift reflects decades of neuroscience and medical research. Twenty years ago, he said, there was still a push and pull between some benefits of alcohol and things known even then to be potentially harmful; over time, clarity on the harms has grown and the balance has shifted in favour of the evidence for negative health effects. The serious problems have not gone away.

He also pointed out that large-scale neuroimaging studies now consistently link higher alcohol consumption to reduced brain volume, reinforcing public health warnings.

Researchers also attribute shifting consumption to broader societal changes, including shifts in social behaviour and loneliness. Much of America's alcohol consumption has historically occurred in group settings, so changes in how people gather socially may be influencing drinking habits.

At the same time, experts caution that a drop in general social drinking does not mean severe alcohol problems have dissolved. Although overall prevalence among adults is falling, the contradiction remains for those whose drinking is at problem level.

Taken together, the picture is clear: health awareness about alcohol is rising in America, and its biggest reflection is among Catholics, whose drinking rate has fallen from 79 percent to 55 percent within a generation, level with Protestants.
