The aim of the article is to evaluate the spatial disproportions in the development of rural municipalities in relation to their financial situation with the use of a non-standard synthetic measure. The analysis in the area of finance and development of communes concerned the years 2011, 2014 and 2017. The study covered 70 rural communes in the Świętokrzyskie Voivodship. Data exploration was possible due to the use of data from the Local Data Bank of the Central Statistical Office and the Regional Audit Chamber. The method used in the work is a synthetic measure of development and the financial situation. Local self-government can fulfil its tasks when it is equipped with stable and efficient sources of income and an appropriate level of endogenous resources. The economic potential, infrastructure, financial resources are an important development factor. The group of communes with the best situation in terms of development was created, among others, by Sitkówka-Nowiny, Morawica and Strawczyn Communes, which are located in the Kielce district and are characterized by a good financial situation and economic potential. The research showed disproportions between rural communes characterized by an industrial function and units with a traditional agricultural function.
