The article reviews differences in the living standard at the level of regions and districts. Living standard is defined and assessed in terms of material living conditions by employing multiple indicators which are grouped in three modules (subject areas): economic development; income and consumption; income inequality and poverty. We employ relevant statistical indicators to measure differences and specific methodology to assess the living standard so that we could rank territorial units according to their distance from the best regional score. The findings of our empirical research of the living standard indicate that: (a) there is a slight trend towards a decrease in the differences between regions, while differences between districts remain the same; (b) there are significant changes in the arrangement of regions and districts according to their scores in the different years of the research; (c) divergent trends are identified in the development of territorial differences measured through the summary scores for the three modules; (d) the living standard has deteriorated in a significant number of the territorial units
