Gallup, which started tracking Americans' alcohol habits more than 80 years ago, says the drop in drinking rates coincides with Americans' growing concerns that even moderate drinking is unhealthy.

A new Gallup survey has found that only 54% of Americans say they drink alcohol — that's lower than at any other point in the past three decades. The poll comes among a growing belief that even moderate drinking is a health risk.

Only 54 percent of American adults say they consume alcohol, according to Gallup, the lowest in the survey’s 90-year history by 1 percentage point.
