About 44% of adults worldwide, roughly 2.3 billion people, drank alcohol in the past year based on 2019 data from the World Health Organization. That means the majority of the global adult population, 56%, actually abstained from drinking entirely during that period. These numbers shift dramatically depending on where you live, your age, and your sex.
Global Drinking by the Numbers
The WHO’s 2019 figures remain the most comprehensive global snapshot available. Of the 2.3 billion or so people who drink, consumption levels vary enormously. Most drinkers consume alcohol occasionally and in small amounts, but a significant portion drinks at levels that damage health. An estimated 400 million people aged 15 and older, about 7% of the world’s adult population, lived with an alcohol use disorder in 2019. Within that group, 209 million people (3.7% of adults globally) met the criteria for alcohol dependence, the more severe end of the spectrum.
Men drink at substantially higher rates than women in virtually every country and every age group. They also account for a disproportionate share of alcohol-related harm.
Where People Drink the Most
Per capita consumption varies widely by country. Eastern Europe consistently leads the world in pure alcohol consumed per person per year. The top five countries, measured in liters of pure alcohol per person aged 15 and older:
- Romania: 16.8 liters
- Georgia: 14.4 liters
- Latvia: 12.9 liters
- Lithuania: 12.1 liters
- Czech Republic: 12.0 liters
To put that in perspective, 16.8 liters of pure alcohol is roughly equivalent to about 450 standard drinks spread over a year, or more than one drink every single day. Countries with large Muslim populations tend to have the lowest consumption rates, with many reporting figures near zero liters per capita.
How Drinking Levels Are Defined
Not all drinking carries the same risk, and public health agencies draw specific lines between categories. The CDC defines them this way:
- Moderate drinking: Up to one drink per day for women, up to two per day for men.
- Binge drinking: Four or more drinks on a single occasion for women, five or more for men.
- Heavy drinking: Eight or more drinks per week for women, 15 or more per week for men.
A “standard drink” in the US means 14 grams of pure alcohol. That’s one 12-ounce beer at 5% strength, one 5-ounce glass of wine, or one 1.5-ounce shot of distilled spirits. Many cocktails and craft beers contain significantly more alcohol than a single standard drink, which makes self-assessment tricky.
Young People and Alcohol
Drinking often starts well before adulthood. In the United States, 22% of high school students reported drinking alcohol in the past 30 days, according to the 2023 Youth Risk Behavior Survey. That number has actually been declining over the past two decades, part of a broader trend of decreasing substance use among American teenagers. Still, early drinking is associated with a higher likelihood of developing problematic drinking patterns later in life.
The Health Toll of Alcohol
Alcohol contributed to 2.6 million deaths worldwide in 2019, accounting for 4.7% of all deaths that year. The causes break down into three broad categories. Noncommunicable diseases, primarily heart disease and cancer, were responsible for the largest share at 1.6 million deaths. Injuries from traffic crashes, self-harm, and violence accounted for 724,000 deaths. Infectious diseases linked to alcohol use caused another 284,000.
Young adults bear a surprising share of this burden. The highest proportion of alcohol-related deaths, 13%, occurred among people aged 20 to 39. In this age group, alcohol-related injuries, particularly car crashes and violence, are the primary drivers. For older adults, the toll shifts toward cancer and cardiovascular disease, conditions that develop over years of cumulative exposure.
Cancer alone killed 401,000 people through alcohol-related mechanisms in 2019. Alcohol is a confirmed carcinogen linked to cancers of the mouth, throat, esophagus, liver, colon, and breast. The risk increases with the amount consumed, and there is no completely “safe” threshold for cancer risk, even at moderate levels.
How Drinking Patterns Are Shifting
Global trends paint a mixed picture. In many high-income Western countries, overall consumption has plateaued or declined slightly, driven partly by younger generations choosing to drink less. The “sober curious” movement and growing availability of non-alcoholic alternatives have accelerated this shift, particularly in the US, UK, and Scandinavia. At the same time, consumption has been rising in parts of Southeast Asia, sub-Saharan Africa, and the Western Pacific region as economies grow and alcohol marketing expands.
The net result is that global per capita consumption has remained relatively stable over the past two decades, even as the geography of drinking continues to change. Whether someone drinks, and how much, still depends heavily on where they were born, their cultural background, and their economic circumstances.
