It seems that not only are some men not contributing at home, they're actually creating more work for their wives.

Despite some positive improvements in gender equality over the past century, Reuters.com confirmed that husbands create, on average, an additional seven hours of household labor for their wives each week. 

Pause to consider what this means for the household laborer—an additional seven hours of labor per week is the equivalent of an eight-hour work day with a one-hour lunch break. The article asserts that men take on more work outside of the home than women, and that might be the root cause of the imbalance of household labor division between the genders for childless couples.

So, what happens when a married couple has children? Reuters says, "Women with more than three children spen[d] twenty-eight hours a week cleaning, cooking and washing." 

Twenty-eight hours—that is the equivalent of four eight-hour work days with a one-hour lunch break—and that's just household cleaning alone.
