The paper deals with unpaid work in Slovak households whilst focusing upon unpaid work performed by younger members of the household. Studies of unpaid work of people up to 26 years are still not well documented in literature. The aim of this paper is twofold: First, it seeks to answer the question whether people with a lower-income status in Slovakia spend more time performing unpaid work in households in comparison to people with a higher-income status, and hence whether household income is an important determinant of unpaid housework performed by younger members of Slovak households. Second, the paper aims to determine also other factors that influence the volume of unpaid housework performed by younger members of Slovakia households. The results suggest that people in lower-income households in Slovakia spend more time in household labour than people in higherincome households. This applies to routine, non-routine as well as care household work. According to the results from a regression analysis, factors different from income are important determinants of household labour of younger members of Slovak households.
