- Loneliness is a universal experience linked to poorer wellbeing, worse health, and higher risk of early death.
- Global survey data shows about 1 in 5 people feel lonely daily, with higher rates in low-income countries (31.3%) than high-income countries (15.7%).
- Social capital (trust and reliable support networks) is a key factor reducing loneliness worldwide.
- Individual circumstances and socio-economic environment both contribute to loneliness; no clear global trend of worsening epidemic was found.
- Tackling loneliness requires different approaches: reducing poverty in low-income countries, and investing in community and public spaces in wealthier ones.
- Loneliness is not just a personal struggle but reflects societal conditions, and addressing it can improve wellbeing and community strength.
