Nina Smith was showing gender differences. That's why she split the data up on genders. One of her conclusions was that the traditional family roles, in which the husband supports the wife, has been taken over by the welfare society so that the woman is now supported by the government. There are many reasons for this difference. First of all, men still tend to seek more managerial positions and jobs in the private sector, making more money. Women have more part time jobs and jobs in the public sector. As Denmark taxes income on a progressive scale women end up paying less tax this way. Another reason is that women live longer and thus have more expensive retirements.
