The main element of sustainable development paradigm are three orders: social, economic and environmental. The social order, due to including the categories of the quality of life in sustainable development, is regarded as a primary objective, i.e. the state of functioning and behaviour of individuals which enables the existence, duration and development of the society as a whole. The study presents spatial variability of social order for rural communities of Lower Silesia voivodeship situated in south-western part of our country. Sustainable development index, which characterises social order, was used in the work. Synthetic index of social order, combining all the analysed indices, was determined for particular communities. In 2000-2010 its value decreased, indicating lack of realisation of sustainable development concept.
