The way mothers and fathers spend their time has changed dramatically in the past half century. Dads are doing more housework and child care; moms more paid work outside the home. Neither has overtaken the other in their "traditional" realms, but their roles are converging, according to a new Pew Research Center analysis of long-term data on time use.

At the same time, roughly equal shares of working mothers and fathers report in a new Pew Research Center survey feeling stressed about juggling work and family life: 56% of working moms and 50% of working dads say they find it very or somewhat difficult to balance these responsibilities.
