Income distribution analysis can be conducted from the point of view of the comparisons between different geographical regions, family types or socio-economic groups it can also be carried out to assess the effects of an economic policy over time. The paper presents the results of a research on income distribution of Polish farmers which allowed us to formulate several conclusions concerning the differentiation of income inequality, poverty and wealth for the households of farmers in different macro-regions. The analysis uses the Gini inequality index and selected poverty and wealth indicators. The basis for the calculations was micro data coming from the Household Budget Survey conducted by the Central Statistical Office of Poland for 2015. The results of the research showed that the highest income inequality among the farmers’ households was observed in the northern region. Also this region was characterised by the highest percentage of households considered affluent. But the lowest Gini inequality coefficient was observed for the south-western region, where there were no farmers’ households exceeding the richness threshold.
