On the basis of the obtained data, a selected group of indicators of environmental, economic and social dimensions has been specified which allows to measure the level of sustainable development in the indicated communes. The analysis of the indicators’ value has, through the usage of ranking process, allowed for extracting of three communes’ groups reflecting differential level of sustainable development. Too significant differences in measurer’s values referring to dimensions of sustainable development in the examined subjects indicate their developmental disharmony which results in placing a commune in a group of a lower level of sustainable development.
