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.

First-time mothers are older in big cities and on the coasts, and younger in rural areas and in the Great Plains and the South. In New York and San Francisco, their average age is 31 and 32. In Todd County, S.D., and Zapata County, Tex., it’s half a generation earlier, at 20 and 21, according to the analysis, which was of all birth certificates in the United States since 1985 and nearly all for the five years prior. It was conducted for The New York Times by Caitlin Myers, an economist who studies reproductive policy at Middlebury College, using data from the National Center for Health Statistics.
