Social Disconnection in a Hyperconnected World: Loneliness, Social Isolation, and Problematic Technology Use Across 35 Nations

There is growing international concern that both loneliness, a subjective experience, and social isolation, an objectively measurable condition, are increasing. The public health consequences of these forms of social disconnection are well documented. However, evidence regarding the relationship between digital technologies and social disconnection remains mixed. As part of Sync’s global digital wellbeing research program, we surveyed loneliness levels and online behaviours (e.g., video game play and social media use) across 35 nations and 35,000 adult participants. This report reviews relevant literature on loneliness, social isolation, and technology use, and also details the results of the cross-national survey. Loneliness was a widespread issue across all participating countries, with Japan experiencing particularly high rates. There was a clear link between problematic technology use and social disconnection across the whole sample and within each nation. The report elaborates on these findings, offering recommendations and suggestions for future research.
