Summary: A major international study of adults ages 50–90 across 29 countries found that middle-aged Americans report higher levels of loneliness than older adults—a pattern seen in only one other nation, the Netherlands. While loneliness typically increases with age in most countries, the United States stands out as an exception. Factors such as unemployment, caregiving burdens, and limited social support systems appear to drive higher isolation among middle-aged adults, highlighting a gap in public health efforts that have traditionally focused on older adults and adolescents.
The research emphasizes that loneliness is linked to poorer physical and mental health and calls for targeted, age-appropriate screening and interventions to address the rising risk among middle-aged people.
Key facts
- U.S. exception: Middle-aged Americans report greater loneliness than older adults, a pattern shared only with the Netherlands in this study.
- Main drivers: Unemployment, caregiving stress, being unmarried, depression, and poor health are important contributors.
- Policy gap: Loneliness programs often overlook middle-aged adults despite their substantial and growing vulnerability.

New international analysis shows middle-aged Americans among the loneliest
Published in the peer-reviewed journal Aging and Mental Health, this study analyzed harmonized survey data from 64,324 adults aged 50–90 across Europe, North America and the Middle East. The research team—led by Robin Richardson, PhD, with collaborators from Columbia University, McGill University and Universidad Mayor—used the three-item UCLA loneliness scale and a decomposition approach to identify how demographic and health factors contribute to age-related differences in loneliness.
Overall, loneliness tended to rise with age across most countries. However, the United States and the Netherlands were notable outliers: in these countries loneliness was more concentrated among younger older adults (middle-aged) than among the oldest study participants. Countries such as Bulgaria and Latvia showed the steepest increases in loneliness with advancing age, while Cyprus and Greece had the highest prevalence of loneliness across the 50–90 age range.
Why are middle-aged adults more lonely in the U.S.?
The analysis found that being unmarried and not working were among the top contributors to age differences in loneliness. But the relative importance of these factors varied by country. In the United States, not working was a leading factor behind elevated loneliness among middle-aged adults, whereas in other countries unemployment tended to be associated with greater loneliness among older adults.
About one fifth of the contributors to age-related loneliness remained unexplained, and this unexplained portion was concentrated among middle-aged adults. The authors suggest this gap may reflect social circumstances common in midlife—limited leisure time, simultaneous demands from work, childcare and caring for aging parents, and weaker public support systems. The U.S. context—characterized in the study by less robust social safety nets and higher out-of-pocket care costs—may intensify vulnerabilities for middle-aged people managing these competing responsibilities.
Implications: what can be done to reduce loneliness?
The researchers underline that loneliness is not an inevitable result of aging and can vary substantially by environment and life circumstances. Because loneliness appears sensitive to changing life conditions, policy and program responses should be tailored to which age groups are most at risk in each setting.
Recommendations from the study include expanding mental health screening—particularly for depression—to include middle-aged adults; improving supports for those who are unemployed or unmarried; and designing country-specific interventions rather than one-size-fits-all approaches. The authors note middle-aged adults juggling work, childcare and caregiving responsibilities may need outreach and services as much as, if not more than, older adults traditionally targeted by loneliness initiatives.
The study acknowledges limitations, including lower response rates in some countries and the potential underreporting of sensitive conditions such as loneliness and depression. To reduce measurement differences, the team harmonized data and applied consistent loneliness measures and analytic methods across all participating countries.

Abstract (brief)
Objectives: Loneliness is common and harms health. While typically assumed to increase with age, the age–loneliness relationship may differ by country. This study examines how demographic and health factors contribute to age-related inequalities in loneliness across countries.
Method: Population-based cross-sectional data from 64,324 adults (ages 50–90) in 29 countries were analyzed. Loneliness was measured with the three-item UCLA scale. The authors used concentration indices to quantify age inequalities and a decomposition method to estimate contributions of demographic and health factors.
Results: In most countries, loneliness was concentrated among the oldest adults. In the United States and the Netherlands, however, loneliness was more concentrated among younger older adults. Major contributors to age inequalities included being unmarried and not working, though the magnitude and mix of contributors varied markedly by country.
Conclusion: Age inequalities in loneliness and their drivers differ substantially across countries, indicating loneliness is shaped by social and environmental contexts rather than being an inevitable consequence of aging. Public health responses should be tailored to local age-risk profiles.
