If you’re in crisis right now — call or text 988 (the U.S. Suicide & Crisis Lifeline), available 24/7. This article looks at the loneliness statistics worldwide and what they mean — it isn’t a substitute for emergency mental-health support.
I’m Landon. I help run How To Beat Loneliness, and part of my job is reading the research so you don’t have to. In 2025 the World Health Organization finally put hard numbers on something most of us only feel — and the loneliness statistics worldwide are worse than almost anyone guessed. Roughly one in six people on the planet is lonely, and loneliness is now tied to about 871,000 deaths a year. If that lands a little too close to home, there’s a free number with a real human on the other end: 877-638-1122.
What the loneliness statistics worldwide actually say
In June 2025 the WHO’s Commission on Social Connection released its first major report on the subject, and the headline figures are hard to shake. About one in six people worldwide reports feeling lonely. Loneliness and social isolation are now linked to roughly 100 deaths every hour — more than 871,000 a year.
To put that in plain terms: social disconnection now sits in the same conversation as smoking and obesity as a driver of early death. The commission is co-chaired by Dr. Vivek Murthy, the former U.S. Surgeon General who called loneliness an epidemic back in 2023 — so the worldwide numbers and the American ones are telling one story.
One of the report’s contributors, Professor Shereen Hussein, summed up the takeaway better than I can: “Social connection is not a luxury — it is a health imperative.” The loneliness statistics worldwide aren’t a soft, feelings-only problem. They’re a health story.
Loneliness isn’t just sad — it’s a measurable health risk
This is the part the global data forces into the open: loneliness shows up in the body. The U.S. Surgeon General’s 2023 advisory found that weak social connection raises the risk of heart disease by 29%, stroke by 32%, and dementia by about 50% in older adults.
The same advisory estimated that the toll of chronic loneliness on early death is comparable to smoking roughly 15 cigarettes a day. We’ve written before about what loneliness does to your body, and about the link between loneliness and memory — the worldwide figures are that same warning, scaled up to eight billion people.
Who the worldwide numbers hit hardest
It’s tempting to picture loneliness as an old-age problem. The data says otherwise. According to the WHO report, between 17% and 21% of people aged 13 to 29 say they feel lonely — with the highest rates among teenagers.
Money and geography matter too. About 24% of people in low-income countries report feeling lonely — roughly twice the rate in wealthy countries (around 11%). Loneliness travels with hardship, not just age.
That said, older adults still carry a heavy share. The report estimates social isolation may affect up to one in three older adults. A handful of things push the risk up across every age:
- Living alone, especially after a loss or a move.
- Poor health, low income, and less education.
- Heavy or negative time online, which the report flags for young people in particular.
What the loneliness statistics worldwide mean for you
Big numbers can numb. That’s the real risk with a figure this large — 871,000 deaths is so abstract it almost stops meaning anything. So here’s the part that matters most: the same research that measures the harm also measures the cure.
The WHO found that people with strong social connection have lower inflammation, less disease, and longer lives. You don’t have to move the loneliness statistics worldwide to change your own corner of them — connection is built one ordinary conversation at a time. A standing call with a friend. A neighbor you actually talk to. One person who knows how your week went.
And on the days you don’t have that person, we built a line for exactly this moment. A real, trained human answers — no script, no fee, no judgment. If you’re curious what it’s like, here’s exactly what happens when you call. You can also start with our guide on how to beat loneliness if you’d rather read first.

And in a crisis, call or text 988 right away.
A note from Landon
Statistics this big can make you feel like one more number. You’re not. Behind the worldwide total is a Tuesday afternoon, a quiet kitchen, and a person who just wants someone to talk to — and that part has a simple answer. The number’s free. Use it.
