The relation between global variations in child mortality rates and socio-economic indicators is an important field of study with broad implications for public health interventions and policies. A nation’s overall health and socioeconomic standing can be determined in large part by looking at its child mortality rate, which reflects the quality of its healthcare system, economic conditions, level of education, and governance. Using a comprehensive set of indicators such as GDP per capita, CO2 emissions per capita, education ratio, Corruption Perception Index (CPI), and the Human Development Index (HDI), this study seeks to identify and analyse the socio-economic factors that significantly influence child mortality rates across different regions.
