“Becoming a mother used to be seen as a unifying milestone for women in the United States. But a new analysis of four decades of births shows that the age that women become mothers varies significantly by geography and education. The result is that children are born into very different family lives, heading for diverging economic futures,” the New York Times reports.
“The difference in when women start families cuts along many of the same lines that divide the country in other ways, and the biggest one is education. Women with college degrees have children an average of seven years later than those without — and often use the years in between to finish school and build their careers and incomes.”
