Life as a vital activity: the relationship between the quality of the population and the quality of its life (part I)

The presented first part of the article is devoted to the consideration of theoretical issues that reveal the concepts of "quality of population" and "quality of life", as well as their relationship. At the center of the study is a person and the historical analysis of social development. In contrast to the econocratic approach, the authors rely on the hypothesis of the complex influence of demographic processes of fertility, mortality, migration, family, relations between men and women, generations on the quality of the population and the quality of its life. It is shown that the influence of the economy on human behavior, including the actual demographic processes: fertility, mortality and migration, is large, but not comprehensive and far from linear. The authors draw the reader's attention to the interdependence of the quality of the population and the quality of its life. Their position is that it is necessary to recognize demography in accordance with its original meaning in the science of describing the people, and not by its "calculation", which continues to dominate in public practice. It is emphasized with a fact that demographic science, in the center of which is the study of the population as a system, its quantity and quality, allows to obtain the results of the long-term impact of demographic processes on the economy and politics necessary to improve the quality of the population based on the growth of the quality of its life. The quality of the population and the quality of its life in the presented study are considered in interaction and mutual influence. The methodological message of the authors - to go from a person, means the deployment of human research from demographic processes to the analysis of the interdependence and interaction of population, economics and politics. In the second part of the article, a person's life will be considered in the unity of a set of needs, interests and values that determine his qua- lity, and the degree of satisfaction with their implementation will be the quality of their life.
