This article analyzes methodological approaches to assessing the level of happiness of the population in Uzbekistan, along with their scientific foundations and practical significance. The level of happiness is considered not only through economic indicators but also as a reflection of a person’s subjective feelings, life satisfaction, social relationships, spiritual values, and psychological stability. Existing international happiness indexes are examined, and the need for a methodology adapted to national conditions for measuring happiness in Uzbekistan is substantiated. The article also elaborates on the socio-philosophical essence of the concept of happiness, as well as its role and impact on societal development.
