Determinants of Under Five Mortality Rate: An Empirical Evidence from Selected Developing Economies

Under-five mortality is a key indicator of child health and overall national development. This study investigates the major factors influencing under-five mortality rates in developing countries. Using panel data and treating the under-five mortality rate as the dependent variable, the authors applied a random effects model to assess the impact of immunization coverage, access to safe drinking water, urban population size, and economic growth. The findings reveal that higher immunization rates, improved access to safe drinking water, and increased urbanization are associated with reductions in under-five mortality. Additionally, economic growth appears to contribute to further declines in child mortality. Based on these results, the study recommends that governments in developing countries enhance healthcare services and invest in public health infrastructure. Furthermore, policies promoting economic growth and improved living standards are essential for better health outcomes among children.
