Loneliness affects 1 in 6 people and is linked to 871,000 deaths a year
WHO's Commission on Social Connection found that 1 in 6 people worldwide experience loneliness, linked to about 871,000 deaths a year, around 100 an hour.
How this affects people
Loneliness is most common among the young: 17–21% of 13–29 year olds report feeling lonely, with the highest rates among teenagers. In low-income countries about 24% of people are affected, roughly twice the rate in high-income countries.
The 871,000 figure is a population-level estimate, not a count of recorded deaths. WHO says the economic costs of loneliness are only beginning to be estimated.
