Priority Areas: Water & Health

Priority areas are identified using local coefficients estimated through Geographically Weighted Regression (GWR), which measures the spatially varying relationship between access to water infrastructure and health using the indicator of under 5 mortality. The tool highlights locations where the local association between access to piped water and the selected health indicator is both negative and statistically significant. The identified areas are classified as having strong, moderate, or mild associations according to the magnitude of the local GWR coefficient. This classification helps users determine the appropriate intensity of intervention. The spatially varying coefficients therefore allow users to identify areas where limited access to piped water is most strongly associated with higher child mortality, supporting targeted interventions, programme planning, and place-based development strategies.
