Women have long proven they can do everything that a man can, but it seems there are some things that men can’t – or won’t do – like laundry.

A new Bureau of Labor Statistics report proves what many women have suspected all along: They do far more household work than men. From 2003 to 2007, women spent an average of 10.8 hours more per week doing unpaid “household work” than men.

The difference is most stark among 25- to 34-year olds, with women spending 31.7 hours per week doing the laundry, cooking and cleaning. That’s about twice as much as men, who spent just 15.8 hours on the same chores. Teenage boys and young males performed the fewest hours of household work – 8.9 hours per week, compared with 15.9 for women.

But there is one thing to look forward to: The difference between men and women narrows as they get older. Those between 65 and 74 years old had the smallest gap, with women performing just 8.2 hours more household work per week.
