Alcohol Consumption by Age Group: Who Drinks the Most?

In the U.S. (NSDUH data), adults aged 25–34 have the highest prevalence of current alcohol use and binge drinking, followed by 18–24 year olds.

Key Statistics (Approximate, Recent Surveys)

• 25–34: ~70% past-month use; ~35% binge (≥5M/4F drinks/occasion)
• 18–24: ~60% past-month; ~30% binge (college peak)
• 35–49: ~65% past-month; ~25% binge
• 50–64: ~55% past-month; ~18% binge
• 65+: ~45% past-month; ~10% binge

Patterns

• Young adults: Higher intensity (binge), lower frequency
• Older adults: Higher frequency (daily/near-daily), lower intensity
• Gender: Men > women in volume & binge; gap narrowing in young adults
• Trend: Gen Z drinking less than prior cohorts; "sober curious" movement

Health Impact

Binge drinking → acute harm (injuries, assault, alcohol poisoning). Chronic heavy use → liver disease, cancer, cardiomyopathy, neuropathy, cognitive decline. No safe level for cancer risk (IARC).

Screening: AUDIT-C, single-question ("How many times in past year...?"). Brief intervention effective in primary care.
