This article is devoted to the study of factors that affect inequality in the housekeeping time allocation among partners in Russia (without considering the time spent on caring for household members). To identify inequality factors, we used nonparametric methods of statistical analysis. Based on data from Selective supervision of use of daily fund of time by the population, we checked the influence of several respondents’ characteristics and characteristics of the households, which respondents are a part of, on the distribution of household duties between partners. The work on the basis of empirical data confirmed a number of hypotheses, in particular, it was shown that there is a significant relationship between the distribution of household responsibilities between partners and the age of each of the partners, self-assessment of partners’ health status, employment status, self-assessment of the financial status of the household, the number of children and their health condition. It should be noted that, according to our estimates, the difference in the time spent by partners is also influenced by the level of education of male partners, while the level of education of female partners does not have a significant effect. In addition, we did not reveal a clear relationship between the dynamics of the indicator we are interested in and the difference in the age of partners, the presence of chronic diseases or disabilities among respondents, marital status, and working conditions.
