More American men are living on their own these days–possibly due to an increase in divorce rates in recent decades and the fact that the children of divorced couples usually live with their mothers.

The share of one-person households in the U.S. maintained by men ages 15 to 64 rose to 34% in 2012, up from 23% in 1970, according to a Census report on the status of families released Tuesday. For women of the same age, this figure actually dropped slightly, to 30% in 2012 from 31% in 1970.
