By life stage
Loneliness at every age
Loneliness shifts in character across a lifetime, different causes, different expressions, different things that help. Here's how it changes by decade.
Teens
13–19
The most connected generation, and among the loneliest.
Smartphone adoption reshaped adolescent social life. Performance replaces presence. Surveys show teen loneliness at record levels.
20s
20–29
The 'best years' that quietly hollow out.
Post-university, everyone disperses. The social infrastructure that made friendship effortless disappears overnight.
30s
30–39
Friendships fade quietly. Nobody planned it.
Partners, kids, careers pull everyone in different directions. By the mid-30s many people have fewer close friends than at any point since childhood.
40s
40–49
Midlife, and the social world keeps shrinking.
Career demands peak. Children consume evenings. The gap between who you are and who your friends knew you as widens.
50s
50–59
The nest empties. The career nears its end.
Children leave. Professional identity starts to shift. The social scaffolding built around family and work begins to contract.
60s+
60 and over
Retirement removes the last automatic structure.
Work ends. Peers move, get ill, or die. Mobility decreases. The social world contracts to its smallest since childhood, but without the same capacity to build anew.
Life transitions
Loneliness often spikes during transitions, when the old social world disappears before the new one is built.
