The article explores the issue of social development of the local communes. This development process is defined as growth and differentiation in the fulfilment of needs of the social groups located on the particular area. There is spectrum of measures that allows us to define level of development and specificity of the particular territorial communes. Author presents the concept of Indicator of Development of Territorial Communes (IDTC) calculated for communes. This indicator is calculated according to the portfolio method and it takes into account both growth factors and barriers of development. The practical use of the IDTC is illustrated on the example of the communes in Zachodniopomorskie Region, for years 1999–2001. The results show uneven and incoherent development of the communes in the region discussed. The further conclusion is that this situation would not change in the short-term perspective.
