The UN Population Divison says people are waiting longer to get married around the world. The World Fertility Report says the mean age for marriage among men changed in one generation from 25.4 to s7.2. For women, the change was from 21.5 to 23.2. The difference is greater in developed countries – from 25.2 to 28.8 among men and from 22.0 to 26.1 among women.
