Subject and purpose of work: The aim of the study is to assess the regional differentiation of the average level of farm income and to answer the question of whether during 2006-2014 there was a tendency towards convergence in this area. Materials and methods: The spatial scope of research included four FADN agricultural regions, whereas the time span covered the years 2006-2014. The numerical data used for the analyses were sourced from standard FADN results. The assessment of convergence was carried out using the coefficient of variation (sigma convergence) and the relative index of changes in the regions compared to the country (beta convergence). Results: The conducted research indicates the existence of regional disproportions in terms of average income level and average labour profitability on farms. The highest average income was achieved throughout all the years covered by research in the region of Pomerania and Masuria, and the lowest one in Lesser Poland and Carpathian Foothills. The research demonstrates that during 2006-2014 there was no convergence in the average level of income and average labour profitability of farms in the FADN regions. Conclusions: Convergence is a long-term process, so the research should be treated as an initial examination of the regional differentiation of the income situation of farms.
