Loneliness Among Gen Z & Millennials — The Silent Mental Health Crisis

1. The Loneliest Generations in Australia

If you picture loneliness as something that mostly affects older people living alone, you might be shocked: the loneliest age group in Australia isn’t retirees—it’s young people aged 15–24.

Recent Australian studies reveal that:

43% of Australians aged 15–25 report feeling lonely—nearly half of an entire generation.
1 in 7 (14%) experience persistent loneliness lasting two years or more.
41% of 18–24-year-olds report long-term loneliness lasting at least eight consecutive weeks.
72% of 16–34-year-olds feel lonely at least one day every week, and 39% experience high levels of loneliness.
Young Australians who experience persistent loneliness are over 7 times more likely to have high or very high psychological distress.

These aren’t small mood dips. Persistent loneliness can trigger cascading effects on mental health, physical health, relationships, education, and career.

2. How Loneliness Sneaks In

Loneliness among Gen Z and Millennials isn’t simply about not having friends—it’s about a lack of meaningful connection. That disconnection is fueled by a mix of social, economic, and technological factors.

The Digital Paradox

Despite being the most connected generations online, many young people feel emotionally disconnected. Social media can create shallow interactions and constant comparison, which often deepens feelings of isolation.

Life Transitions and Disrupted Support Systems

Moving out, starting university, or entering the workforce can mean leaving behind established support networks. Financial instability and housing insecurity can make it harder to maintain relationships.

The Post-COVID Shift

Lockdowns intensified loneliness rates, and while restrictions have lifted, the habit of staying in has stuck for many. Some have lost confidence in socializing altogether.

Cost of Living Pressures

Rising rent and daily expenses make social outings harder to afford, pushing many young people into further isolation.

3. Why Loneliness Is a Health Issue — Not Just a Mood

The science is clear: chronic loneliness is a public health risk.

Comparable to smoking 15 cigarettes a day in terms of mortality risk
Linked to depression, anxiety, and increased risk of self-harm
Associated with poor cardiovascular health and weakened immunity
Can lead to early vascular dysfunction—even in young adults

Persistent loneliness creates a cycle: poor mental health fuels withdrawal, and withdrawal deepens loneliness.

4. What’s Unique for Gen Z and Millennials

These generations are dealing with challenges no other group has faced in quite the same way:

Social media comparison culture that fuels insecurity
Reduced in-person communication skills due to reliance on texting and online platforms
Transactional dating culture from apps, which can make relationships feel less authentic
Frequent relocation for work or study, disrupting support networks

5. The Rising Psychological Distress

Rates of high or very high psychological distress in Australians aged 15–24 have nearly doubled since 2007—reaching 42% in 2021. Persistent loneliness is a major driver behind these numbers.

6. Recognizing the Signs

Loneliness doesn’t always mean being alone. Signs may include:

Avoiding social events for no clear reason
Feeling drained by interactions
Trouble concentrating
Persistent fatigue or unexplained physical symptoms
Over-reliance on social media for validation
