Is the ‘loneliness epidemic’ real?

What does it mean if you say that something is an epidemic? In the case of a virus, it usually means that it is spreading rapidly and that more and more people are getting infected. When a disease isn’t on the rise but is there in a population at a reasonably steady level, we tend to say that the disease is endemic. But what if the thing you’re talking about is not a virus, but a feeling? In 2023, the US surgeon general launched a report called “Our Epidemic of Loneliness and Isolation”, warning of the health harms of being lonely and socially isolated. The idea that there is an epidemic of loneliness didn’t start there - the term was already in use in the US in the 2010s. And it’s a phrase that’s still going strong, popping up in news stories on a regular basis. After that warning from the US Surgeon General, the World Health Organisation launched the Commission on Social Connection, with their director general warning that “more and more people are finding themselves isolated and lonely.” But is it true that loneliness rates are increasing? Is it right to say we’re in the midst of an epidemic of loneliness? It’s hard to find the data that backs up this claim.
