Roughly 2.3 billion people worldwide drink alcohol, based on World Health Organization data showing that 44% of adults consumed alcohol within a 12-month period as of 2019. That means the majority of the global adult population, 56%, actually abstained entirely. In the United States, drinking is more common than the global average, but patterns of use vary widely, from occasional social drinking to levels that qualify as a clinical disorder.
Global Alcohol Use
The WHO’s 44% figure translates to nearly one in two adults on the planet having at least one drink in the past year. But that number masks enormous regional differences. Drinking rates are highest in Europe and the Americas and lowest in Southeast Asia and the Eastern Mediterranean, where cultural and religious norms discourage alcohol. “Adults” in this context means people aged 15 and older, so the figure captures a broad swath of the population.
It’s worth noting that drinking “in the past 12 months” is a low bar. It includes someone who had a single glass of champagne at a wedding alongside someone who drinks daily. The number tells you how widespread any contact with alcohol is, not how many people drink regularly or heavily.
Alcohol Use in the United States
American adults drink at rates well above the global average. National surveys consistently show that more than half of U.S. adults had at least one drink in the past month, placing the country among the higher-consumption nations worldwide.
Within that broad group, the CDC breaks down drinking patterns further. About 17% of U.S. adults binge drink, meaning they consume four or more drinks (for women) or five or more drinks (for men) on a single occasion. Another 6% drink heavily, defined as eight or more drinks per week for women or 15 or more per week for men. Nearly all heavy drinkers also binge drink, and over 90% of adults who drink excessively report binge drinking as their primary pattern. Men tend to drink more overall and binge drink more frequently than women, though that gap has been narrowing in recent years.
Alcohol Use Disorder
Drinking becomes a diagnosable condition when a person loses consistent control over how much they consume, keeps drinking despite problems it causes, or experiences withdrawal symptoms. As of 2022, more than 29 million Americans aged 12 and older met the criteria for alcohol use disorder. That’s roughly one in nine adults, making it one of the most common substance use disorders in the country.
The gap between how many people have AUD and how many get treatment is significant. Most people with the disorder never receive any form of help, whether that’s medication, therapy, or a recovery program. This treatment gap persists even though effective options exist, largely because of stigma, cost, and the widespread belief that problem drinking is a personal failing rather than a medical condition.
Underage Drinking
Alcohol remains the most commonly used substance among teenagers. CDC data shows that 22% of high school students reported drinking alcohol in the past 30 days, and 9% reported binge drinking in that same window. These numbers have actually declined significantly over the past two decades, part of a broader trend of teens using fewer substances overall. Still, early drinking is a concern because the adolescent brain is more vulnerable to alcohol’s effects on memory, learning, and impulse control, and people who begin drinking before age 15 are substantially more likely to develop alcohol use disorder later in life.
Deaths and Economic Costs
Alcohol contributes to death through dozens of pathways: liver disease, certain cancers, heart disease, stroke, accidents, and violence among them. In 2023, alcohol-impaired driving alone killed 12,429 people in the United States, accounting for 30% of all traffic fatalities. That’s just one category. When you add in liver cirrhosis, alcohol-related cancers, overdoses involving alcohol, and other causes, the total burden is far larger.
The financial toll is staggering as well. Excessive alcohol use cost the U.S. economy an estimated $249 billion in 2010, the most recent year with a comprehensive analysis. That figure includes healthcare spending, lost workplace productivity, criminal justice costs, and motor vehicle crashes. Adjusted for inflation and rising consumption, the current figure is almost certainly higher. About 77% of those costs fell on federal, state, and local governments or on people other than the drinker, meaning the economic burden of excessive drinking is largely shared by society at large.
Putting the Numbers in Context
The simplest answer to “how many people use alcohol” is that billions do globally and well over half of American adults do domestically. But the more useful takeaway is how unevenly that use is distributed. A relatively small percentage of drinkers account for the vast majority of alcohol consumed and the vast majority of harm. Most people who drink do so moderately and without major consequences. The public health concern centers on the roughly one in five to one in six drinkers whose consumption patterns cross into binge, heavy, or disordered territory, where the risks to health, safety, and economic stability escalate sharply.
