A significant cultural shift is underway in Australia as research indicates that younger generations, particularly Generation Z, are increasingly choosing to abstain from alcohol. A study led by Flinders University reveals that this trend could have long-lasting implications for public health and social norms in the country.
The study, which analyzed over two decades of data from more than 23,000 individuals, offers a comprehensive look at drinking habits across five generations. It highlights a notable divergence in alcohol consumption patterns, with older Australians continuing to drink regularly while younger individuals are opting for sobriety.
According to Dr. Gianluca Di Censo, lead author from Flinders’ College of Medicine and Public Health, the findings illustrate that Generation Z is spearheading this cultural transformation. “Our research shows that over the course of their lives, Gen Z are nearly 20 times more likely to choose not to drink alcohol compared to Baby Boomers, even after adjusting for sociodemographic factors,” he stated. “This isn’t just a phase; it appears to be a sustained change in behaviour that could have long-term public health benefits.”
While early adulthood typically sees the lowest levels of alcohol abstinence, the study found that Generation Z members are more likely to avoid alcohol than previous generations at the same age. Young Australians are increasingly replacing traditional alcoholic beverages with mocktails and wellness drinks, reflecting a broader trend towards health-conscious consumption.
The research indicates that Millennials are also drinking less than Baby Boomers overall, although they tend to engage in heavier drinking during specific occasions. This trend raises ongoing concerns about binge drinking among younger adults.
Dr. Kirrilly Thompson, co-author of the study, emphasized that the findings challenge long-standing perceptions regarding Australian social life. “For decades, alcohol has been deeply embedded in social life, but that’s changing,” she noted. “Younger Australians are growing up in a different world — one where abstaining from alcohol is increasingly normal. Digital socializing, rising living costs, and health awareness are reshaping how people spend their time and money.”
The research further reveals that the Silent Generation, born before 1946, exhibits the highest levels of weekly alcohol consumption, surpassing even Baby Boomers. This highlights ongoing health risks for older Australians, prompting the need for targeted public health strategies.
The authors of the study believe that understanding the motivations behind the decline in alcohol use among younger individuals can inform future health campaigns. “If we can understand what’s driving this decline, whether it’s economic pressures, social norms, or policy changes, we can use that knowledge to support healthier behaviours across all age groups,” said Dr. Di Censo.
Potential strategies to support this trend could include minimum alcohol pricing, advertising restrictions, and tailored health messaging. Dr. Thompson expressed optimism about the implications of these findings. “This research shows that change is possible. Generation Z are redefining what it means to socialise and celebrate, and they’re doing it with less alcohol. That’s something we should be paying attention to, not just as researchers, but as a society.”
The peer-reviewed paper, titled “OK Boomer: A longitudinal analysis unravelling generational cohort differences in alcohol consumption among Australians,” has been published in the journal Addiction. The insights gained from this research could significantly impact health strategies and public policy in Australia as the nation adapts to evolving social norms surrounding alcohol consumption.
