Researchers also found that having children increased the amount of housework done by women, but seemed to reduce the amount done by men.

Married women with more than three children did an average of 28 hours per week, more than 10 hours more than the average woman.

In contrast, married men with more than three children did around 10 hours of housework per week, compared to 13 hours completed by the average man.
