The aim of the paper was to indicate differences in income from agricultural activity earned by farm owners located in different zones under the influence of a big city. The study covered entities from six voivodships: Lower Silesia, Lubelskie, Lesser Poland, Masovia, Pomerania and Greater Poland. The database of the Polish FADN system was the source of data presented in the analysis. The outer and inner metropolitan zone have been distinguished as well as the group of objects located outside metropolitan areas. For the distinguished groups, a comparative analysis was carried out. Research pinpointed that in the inner metropolitan area zone, there was evidently a considerably higher income from a farm on one unit of own work and the estimate rate of wage for an hour of hired work. The average value of these categories was diminishing in subsequent zones along with moving away from the core of metropolitan areas. Apart from that, in all the three researched groups of farms, the average rate of wage of own work was higher than the rate of wage of hired work. This means that farm owners also take wages from management and the incurred economy risk. The height of these wages is subjected to considerable fluctuation that result from e.g., observed economic fluctuations in agriculture.
