The aim of the study was to present the income situation of farmers' households in Poland, in comparison with other social and economic groups of the population, depending on the number of people in a household. Based on the research of household budgets carried out by the Central Statistical Office, the level of real income and its changes between 1999 and 2008 were presented, and a projection for 2009 and 2010 was drawn up. The analysis carried out shows that between 1999 and 2008 the income situation of households was significantly diversified. The higher number of household members entailed a better income situation of farmers' households as compared to other social and economic groups. Income disproportions between farmers' households are expected to decline, compared to other social and economic groups, as a result of the growth of their real disposable income. In 2009 and 2010, households of pensioners, irrespective of the number of their members, will obtain the lowest real income, as compared to farmers, while the highest income will be generated in households of the self-employed (except for 5-member households).
