Researchers used data from more than 17,000 young people in Germany and the United Kingdom. All participants had no previous relationship experience at the start and were surveyed each year between ages 16 and 29.
The study found that being single for long periods relates to a sharper drop in life satisfaction and to more loneliness, especially in the late twenties. Symptoms of depression also increased at that age. The team found that men, people with higher education, those with lower current well-being, and people who live alone or with a parent were more likely to stay single longer. When people formed a first partnership, life satisfaction rose and loneliness fell, both short term and long term, but depressive symptoms did not show the same improvement.
