In Poland, as in other EU countries, the share of single-person households is on the increase. On the one hand, living alone allows
one to have their property, income and leisure time at their free disposal; on the other hand, it forces them to obtain funds on their
own to run the household. The purpose of the paper is to assess the income situation of single-person households (income levels
and income inequalities), as well as to identify determinants conditioning the income amount. Research results indicate a better
situation of single-person households than of those multi-person ones in terms of the income level, and smaller income
inequalities in this group of households.
