Sociology
The Demography of Singlehood and the Deinstitutionalization of Marriage
Quick fact
In Japan, over 40% of people in their 30s have never married by age 40, a figure that has tripled since 1980, while in Niger nearly 90% of women are married by age 30.
Why this is interesting
Imagine two countries: in one, almost everyone marries by age 30; in another, over half of adults live alone. What forces drive such different life paths?
