Would you please correct me/?

The bar diagram shows the distribution of unpaid work hours per week who spent by married men and women spent. As it is clears, unpaid work hours per week doesn’t isn't distributed between them equally.
When there is no child in the family, married women do housework nearly twice more often than men.
As children are born, in these cases (1-2 or more than three children), married women do houseworks almost three times more often than men. It is clear that by increasing  when the number of children rises, women have to spend more time for doing (or "performing") houseworks, but the steep of it rate of increase is steady. However, men spend less time on unpaid work when children are born.
In conclusion, we can see that married women generally have so much unpaid work to do at home generally, but their responsibilities are much more far greater than those of men at home when after children were are born. Maybe It can may be worthwhile to mentioned, however, that the role of men are is dominant in this culture and they spend more time to at work outside of the home providing for the family's financial support.
