“One in six women and one in four men have not yet had children by the age of 45. One of the reasons is that women do not want to have children with men of lower status,” says the researcher.

In one generation, the proportion of childless women has increased from 9 to 15 percent among 45-year-old women and from 14 to 25 percent among men of the same age. This is far more than the 5 to 10 percent who state that they do not want to have children."
