The differences are significant considering that while in households in quintile I women spend an average of 46 hours per week on unpaid work, those in quintile V spend almost 32 hours. Meanwhile, the differences in the amount of time spent on unpaid work between men in quintile I and V households are not significant, they are generally less than one hour per day. This shows that men's contribution to domestic and care work is generally independent of socioeconomic stratum, and that the gender gap is even wider and more unjust in the lowest-income households.
