MWITA-CC-2026-010 · Evidence A · P1
WHO's 2025 synthesis estimated 15.8% global loneliness for 2014-2023, with higher estimates among adolescents and in low-income countries than among older adults and high-income countries.
Counterevidence & uncertainty
Loneliness is subjective, instruments and coverage vary, pooled estimates span a decade, and associations do not identify a universal mechanism or intervention effect.
What would change the reading
Update with harmonized post-2023 surveys and intervention trials by context.
