The income of farmers and their families is the base for consumption, savings, and investment. However, apart from its level and adequate ratios to the income of the agricultural population, its stability is also important. This very thesis is the main axis of the analysis of the income situation of Polish farmers participating in the FADN from 2004 to2018. Its documentation is also one of the main aims of this paper. To do this from the right theoretical perspective, theinitial part of the paper presents the schemes of this income calculation and its determinants, as well as issues related to measuring income risk and the factors which affect it. Both static and dynamic approaches were used in this part of the paper. The other, thoroughly empirical and retrospective part of the paper focuses on the relationships between income and budget support, economic size, production type, and spatial location of agricultural farms. The importance of non-agricultural income was also shown, although relevant information in the FADN is not very extensive. The identification of the risk-income strategy should also be treated as a preliminary approach to the analyzed issue.
