Economically developed states. What is hidden behind this concept, how to evaluate or understand why some states are developed and others are not. For example, in their book Why Some Countries Are Rich and Others Are Poor, D. Acemoglu and D. Robinson carry out a lot of research on this topic. Where analysis of historical data, economic and political components, geography and location, democratic and other regimes is carried out. In the course of their research, they came to the conclusion that rich and developed countries are formed under the influence of inclusive economic institutions, which were established more than one hundred years ago. In our study, we assessed indicators that characterize not only the economic component, but the demographic, social, etc. And we came to the conclusion that there is great ambiguity in the understanding of which countries can be called developed or developing. Therefore, with such an assessment, it is necessary to consider the whole structure of the country, from its economic components to the climatic zone in which it is located.
