In the modern world, the development of the economy of any country is closely linked to the sustainable development of regions. Social processes play a crucial role in the sustainable development of a region. Much attention is paid to these processes in scientific works on economics, politics, sociology and interdisciplinary studies. We have touched upon the economic aspects of social development of regions. When writing the article such methods of scientific cognition as system approach, comparative and statistical analysis were used. The data on average monthly wages were used. Taking into account the presence of other sources of income, we also analysed the data on nominal cash incomes of the population by regions. In the analysis we used average per capita indicators to adjust for differences in the population size of the regions. The comparison was carried out using the unevenness index. The calculations revealed that the unevenness of both indicators is growing, which does not correspond to the current trends of sustainable development. The importance of the problem of sustainable development of regions in terms of social development is obvious, so we believe that the results of the research conducted in this article can be used for further scientific developments. Keywords: social development, sustainable growth, unevenness, regions, Kazakhstan, economy, wages, income, population, standard deviation.
