The development of societies today is inequal, and the modern approach to deal with this situation is through the idea of inclusive

development. Its descriptive definition emphasises the problems of inequality, poverty, growth, employment, development and social

welfare, as well as the search for instruments to measure this state in order not to be a ‘mirage’. The existing approaches rely on

indices to evaluate the degree of inclusion, as most of them compare economic with social and ecological results. The report aims

to address the problem of measuring the inclusive development of districts in Bulgaria through the evaluation of an index of social

progress. The tasks include the establishment of suitable indicators to include in the index, an evaluation of the district development

in accordance with the selected indicators, ranking the districts, and evaluating inclusiveness towards the average results of the

state. The results show that the districts develop socially heterogeneously and not inclusively, since not all of them demonstrate the

successful satisfaction of the basic social needs of citizens, which hamper their ability to reach their full potential.
