A new survey report from Pew Research Centers:
While mothers and fathers offer somewhat different views of the division of labor in their household, there is general agreement about who in their family is more job- or career-focused. For example, in two-parent households where the mother and father work full time, 62% say both are equally focused on work, while about one-in-five (22%) say the father is more focused and 15% say the mother is. Differences in the responses to this question between mothers and fathers in this type of household are modest.
