      abstract = {The article presents the analysis of economic size of  private farms in Poland in the years 2004-2012. The
average  farm in the province was adopted as the research unit. The  main aim of the study was to assess the
regional diversity  of economic size of farms and its changes over time.  However, changing the definition of
a farm has caused an  additional problem, due to the heterogeneity of data.  Therefore, in the first part of the
research, for each  region and years 2004-2009, number of individual farms that  have met the current definition
was estimated. The next  step was to evaluate the economic size of average farm. The  economic size of farm
determines production capacity of the  farm, expressed as its potential income. Based on the  economic size of
the farm, estimated for each of the years  of research, the rankings of regions were created. High  concordance of
rankings suggested that the division of  provinces into groups with similar levels of development of  agriculture
would be stable over time. This assumption was  verified by standard deviation method.},
