Population is the main factor in the successful development of any country. The peculiarity of the population is that it is constantly being restored in the process of reproduction of life and is in a state of self-development, which is the main component of any society. Population growth plays a key role in the development of the modern crisis caused by the incompatibility of a large population and techno genic civilization with the stability of the Earth's biosphere. Studying the size, composition and dynamics of the population makes it possible to evaluate the socioeconomic development of the country and its trends. These indicators dictate the necessary measures to neutralize negative processes in the structure of the population and strengthen positive trends in its development. Population growth, depletion and limited resources lead to the deterioration of the economic condition and excessive pollution of the environment. In this framework the efficient management of energy resources is of particular importance as an essential element of sustainable development processes both at national and regional levels. The sustainable development case is being discussed in many aspects within various scientific fields. Scientists conducting research in the field of sustainable development are studying the impact of population on sustainable development and want to reveal more detailed information about this relationship. This article provides a description and dynamics of the population, which is considered one of the main factors for the successful development of any country, its constant renewal in the process of life reproduction and self-development, which is the main component of any society. This article discusses the challenges of increasing population growth and ensuring adequate energy resources. This mismatch and imbalance create certain contradictions in this direction and require the development of new management methods and possibly new research opportunities. As a result, it is asserted that developed countries must move towards zero greenhouse gas emissions and implement strategies to eliminate the harmful effects of human activities on the environment. Therefore, it is time to reconsider the ways of production and consumption of life support resources. This study presents a systematic approach and theoretical analysis of the problem under investigation. The systemic approach and indicators of theoretical analysis showed that demographic characteristics and consumption levels are important factors influencing the success of sustainable development goals. The study concludes that in order to rely on sustainable socio-economic development in the future, it is necessary to balance control over population growth, resources needed to support the population, and the environmental situation in the region.
