The economic development of any country in the world is primarily determined by the level
and quality of life of its citizens. Indicators of quality of life are key factors in assessing the social
and economic impact of ongoing reforms and evaluating the level of social stability and tension in
society. At present, improving the quality of life of the population is one of the key strategic
priorities for ensuring sustainable development. Taking these aspects into account, this research was
conducted to assess the quality of human life, analyze its role in modern society, and identify
effective ways to improve it.
The article examines quality of life assessment indicators, including GDP, Human
Development Index (HDI), Environmental Sustainability Index (ESI), life expectancy, and
Happiness Index, which were used to analyze the development levels of various countries. Based on
data from Numbeo, one of the leading organizations in global quality of life assessment, the study
compares the indicators of countries with high, medium, and low levels of quality of life,
identifying their key differences.
The research methodology included data collection, comparative analysis, statistical data
processing, and index evaluation. The findings indicate that economic diversification, improvements
in healthcare and education systems, environmental sustainability, and strengthening social justice are
essential for enhancing the quality of life. The results obtained can be applied in future scientific
studies in this field, as well as in quality of life assessment centers as a practical tool.
