An upward curve
One of the most striking findings of recent research is the shifting age distribution of loneliness. Studies in the 1970s and 1980s showed an upward curve: loneliness increased with age. Over the last two decades, that pattern has reversed.
“Today, in Quebec and Canada, loneliness is most prevalent among teens and young adults, and in Europe, among adults in their late 20s and 30s,” said Van de Velde. “This trend accelerated with the COVID-19 pandemic, which affected young people in particular. In the latest surveys, young people are more likely to report feeling lonely than older people.”
Loneliness also affects the community at large. Van de Velde gave the example of “kodokushi”—a Japanese term for people who die alone and remain undiscovered for some time. This phenomenon has now spread to North America and Europe. In response, some countries have created government ministries dedicated to addressing solitude.
Another alarming development is the rise in forms of social withdrawal such as “hikikomori”—another Japanese term, signifying young people who shut themselves up in their homes and sever ties with the outside world.
“This major shift raises questions about contemporary social structures,” said Van de Velde. “Sociologists are trying to understand how structural factors such as competition, pressure for academic success, mobility and unemployment contribute to the growing loneliness of younger generations.”
Loneliness also has a political dimension that sociology can help illuminate. “Loneliness kills,” Van de Velde noted, citing evidence that chronic loneliness is equivalent to smoking several cigarettes a day.
Furthermore, loneliness can fuel radicalization. Van de Velde pointed to incels, men who feel excluded from romantic relationships and develop violent resentment towards women and other social groups.
“In (philosopher) Hannah Arendt’s typology, the highest degree of loneliness is abandonment or desolation,” Van de Velde noted. “And when people see no possibility of collective action, democracy itself is in danger.”
