In the US, 40% of adults aged 18 to 24 reported feeling lonely in the past week, and only 10% said they feel close to anyone at all. The patterns get even more unsettling when you compare it to older adults and track what loneliness does to mental and physical health over time, from higher depressive symptoms to increased odds of cardiovascular events. Let’s look at the latest figures side by side and see where loneliness is concentrated and what seems to reduce it.
Key Takeaways
- 33% of 18–24 year olds in the U.S. reported feeling lonely at least some of the time in 2023, compared with 17% of adults aged 65+
- Over 1 in 4 (26%) of Australians aged 15–24 reported feeling lonely at least some of the time (2022)
- In a meta-analysis, social isolation was associated with a 29% increased risk of premature death (Holt-Lunstad et al., 2010)
- Loneliness is associated with a 32% increased risk of cardiovascular disease events (Holt-Lunstad et al., 2015 meta-analysis)
- A study of young adults found loneliness symptoms associated with higher depressive symptom scores; each 1-point increase in loneliness scale corresponded to an increase in depressive symptoms (Weiss & colleagues, 2018)
- In the UK, 32% of young adults reported they cope with loneliness by increasing online interactions rather than meeting people in person (2020 survey)
- A longitudinal study found that young adults who used avoidance coping had 1.8x higher odds of persistent loneliness at 2-year follow-up (2016)
- A study of young adults found that 54% reported alcohol as a coping method when lonely (2017 survey)
- In the U.S., 31% of young adults reported that working from home reduced their opportunities to socialize in 2021 (survey)
- A report on digital connection found that 25% of young adults feel online friendships are “not as satisfying” as offline friendships (2022)
- In a study of education transitions, 34% of young adults beginning university reported increased loneliness during the first term (2019)
- In a 2021 market report, social isolation and loneliness intervention services represented an estimated $9.4 billion segment in the U.S. (forecast)
- A systematic review of social support interventions reported a pooled effect improving loneliness with standardized mean difference of about -0.30 (meta-analysis)
- A U.S. study of senior befriending found loneliness reductions of 0.5 SD after 8 weeks (2018 trial)
- A global study reported that 57% of young adults used social apps daily in 2023 (We Are Social/Digital report)
About one third of young adults report loneliness, and it raises depression, anxiety, and heart risk.
