Explanation
The claim needs a comparison: less than older generations, or less than before? Some evidence supports lower drinking among younger adults, but a blanket claim that Gen Z is increasingly drinking less is misleading.
Gallup found that drinking participation among Americans aged 18–34 fell from 72% in 2001–2003 to 62% in 2021–2023, although that age group is not exclusively Gen Z. In contrast, IWSR's 2026 survey reported that legal-drinking-age Gen Z participation across 15 markets had risen from 66% three years earlier to 74%, still below millennials' 81%. Morning Consult independently reported increased weekly bar and restaurant drinking among U.S. Gen Z adults between late 2024 and mid-2026.
Participation, frequency and total alcohol consumed are different measures. These surveys also cover different populations, and a generation's composition changes as more members reach legal drinking age. The evidence supports specific comparisons, not a universal or continuously declining global trend.
Key takeaway
Gen Z can drink less than millennials while becoming more likely to drink than it was a few years ago.
