The findings of a survey across 142 countries reveal a surprising trend: while almost a quarter of people worldwide reported feeling very or fairly lonely, the loneliest group was not the elderly, as commonly assumed. Instead, young adults aged 19 to 29 reported the highest rates of loneliness at 27%. This finding challenges the conventional wisdom that loneliness is primarily an issue of aging. The survey's breakdown by age shows that the majority of adults aged 45 and older do not feel lonely, while fewer than half of those under 45 can say the same. This discrepancy highlights the need to reconsider our assumptions about loneliness and its impact on different age groups.
The survey's methodology, based on self-reported feelings, is a limitation to consider. China was not included in the survey, and the figures reflect how people described their own feelings, rather than a clinical measure. However, the age pattern held across a large sample representing about 77% of the world's adult population, making it difficult to dismiss as noise. Ellyn Maese, a senior research consultant at Gallup, emphasizes that loneliness is not just a problem of aging but can affect everyone at any age.
The reasons behind young-adult loneliness are multifaceted. The years from 19 to 29 are marked by frequent life changes, such as moving for work or study, leaving the social structure of school, forming and dissolving households, and rebuilding close relationships. A 2025 study in PLOS One suggests that the ability to hold onto friends while adapting to these changes is more critical than the number of friends one has. This perspective offers a hopeful interpretation, suggesting that loneliness may be a growing pain rather than a persistent isolation.
However, a competing explanation focuses on the way young adults connect online. Vivek Murthy, the U.S. Surgeon General, has noted a cultural shift in how relationships are maintained, moving from having confidants to contacts, from having friends to having followers. This shift from quality to quantity of connections may contribute to feelings of loneliness, but it is not the sole factor, according to the survey.
The survey's finding highlights the complexity of loneliness and the need to move beyond simplistic assumptions. The word 'lonely' is used to describe a feeling, not a diagnosis, and feelings of loneliness can vary widely depending on circumstances and cultural context. The data does not suggest that young adults are abandoned or that older adults have it easy; rather, it indicates that the people most likely to describe themselves as lonely are those in the middle of building an adult life.
The direction of travel remains an open question. Will the loneliness reported by young adults ease as their lives stabilize, or will this cohort carry a higher baseline of loneliness as they age? Only long-term follow-up studies can provide a definitive answer. For those who feel close to these findings, seeking support from a qualified counselor or therapist is recommended, as reading about a pattern is not the same as receiving support for personal experiences.
