The article analyzes the role of the well-being of the population in socio-economic development and its main determinants. Relevant recommendations are developed for improving state policy to improve the well-being of the population.

The article presents groundbreaking research using advanced econometric models to understand the complex relationships between infant mortality, under-5 mortality, and female mortality in foreign countries. Conventional least-squares regression (OLS) and structural equation modeling (SEM) techniques were used to analyze data from 121 countries around the world to identify the complex interplay of factors that influence these important mortality rates. Approaches have also been developed to identify subtle dynamics affecting maternal and child health outcomes and to reduce mortality. The approaches and proposals of the authors are presented in the study.
