This researcher studies data from the Panel Study of Income Dynamics and finds that, on average, working women spend more time on housework than working men from similar demographic groups. Married working men with no children spent about 7.5 hours per week on housework, married working women with no children 15 hours. Not-married working women with children spent about 14 hours per week on housework, not-married working men with children 10.5 hours.
