The diagram compares the number of unpaid work hours per week between married men and women in the same household. As an overall trend, it can be seen that the number of hours women perform unpaid work increases considerably with the growth of the children, while that number only slightly increases for men.
In households where there are no children, women perform 30 hours per week in unpaid work. Meanwhile, menís contribution for this kind of work is only about 18 hours.
When children enter the household, the inequality becomes even more pronounced. In a family containing one or two children, men maintain approximately the same level of hours working as in a childless household. However, the number of hours women work without being paid increases to over 50 hours.
The highesrt level of inequality appears to take place in households containing three or more children. Menís contribution to unpaid work declines slightly to 17 hours per week, whereas women spend up to 66 hours performing unpaid work, nearly four times as much as men.
In conclusion, it is clear that the number of hours women perform unpaid work is always higher than men and the gap becomes larger when there are children in the household.
