Few human experiences are as common – or as poorly understood – as loneliness.
More than simply a blue feeling and the inspiration for countless songs, it is linked to poorer wellbeing, worse mental and physical health and a higher risk of early death.
Even within the age of social media, we hear of loneliness being on the rise in every single place – to the extent that some have labelled it an epidemic.
To construct a higher picture, we analysed responses to the Gallup World Poll from more than 218,000 individuals, throughout practically 150 nations. We discovered round one in 5 individuals reported feeling lonely throughout a typical day.
But that global common masked a stark divide.
In high-income nations, 15.7 p.c of individuals reported loneliness, together with 16.2 p.c in New Zealand and 17.8 p.c in Australia. In low-income nations, in contrast, practically one in three individuals (31.3 p.c) reported feeling lonely.
The findings problem the traditional concept that loneliness is just a non-public battle. Instead, they counsel it is usually a social situation, influenced by the financial circumstances, establishments and power of neighborhood life.
The global picture
Across the information we analysed, one issue persistently stood out. That was the significance of social capital; the presence of belief and dependable help networks. People who report having others they’ll depend upon are far much less prone to really feel lonely in each area of the world.
Other factors, similar to poor well being, unemployment and never having a accomplice, additionally performed a half. People with more training tended to be much less lonely in middle- and high-income nations. That relationship was a lot weaker in low-income nations, the place wider social and financial circumstances play a greater position.
These findings led us to conclude that loneliness can typically be the results of a individual’s particular person circumstances, along with their wider social and financial surroundings.
But was there proof of a worsening global loneliness epidemic? While a popular idea, after we checked out knowledge from 113 nations, between 2023 and 2024, we discovered no clear pattern. In truth, slightly below two thirds of nations appeared to report decrease charges in 2024 than 2023.
Again, this wasn’t uniform. While reported charges of loneliness rose considerably in low-income nations, they remained broadly unchanged in middle-income nations and declined in high-income nations.
Importantly, our findings shouldn’t be taken to imply loneliness is any less serious. It impacts a substantial share of the global inhabitants and is strongly linked to poorer wellbeing, emotional misery and a vary of opposed well being outcomes.

Lessons for tackling loneliness
The penalties of loneliness prolong far beyond feeling sad. Across all areas and revenue teams, individuals who reported loneliness tended to have decrease life satisfaction; each within the current and in expectations for the long run, although this affiliation is smaller.
They had been additionally far more prone to expertise stress, fear, anger and bodily ache, and far much less prone to report enjoyment of their day by day lives. While the power of those relationships assorted, the general sample was remarkably constant throughout nations.
Our findings additionally counsel there is not any single resolution to loneliness. In low-income nations, the place loneliness is each more frequent and rising, decreasing poverty, enhancing well being programs and increasing social safety may all assist individuals construct stronger social connections.
In wealthier nations, the place loneliness is much less frequent however nonetheless impacts thousands and thousands of individuals, the challenge may be different. Investing in neighborhood organisations, public areas and different alternatives for individuals to construct trusted relationships may show simply as essential as increasing psychological well being providers.
More broadly, our findings counsel loneliness must be seen as more than a person psychological expertise. It additionally displays the power of the societies individuals dwell in.
That has implications that attain nicely past well being. Tackling loneliness has the potential to enhance wellbeing, increase productiveness and assist construct stronger, more linked communities.
