Health and Population

A Health and Population Survey is a systematic data collection effort aimed at gathering information about the health status, demographic characteristics, and living conditions of a population. These surveys are crucial for policymakers, researchers, and public health professionals to assess health trends, identify disparities, and plan interventions.
