This dataset contains data from 2001 with estimates of the Belgian Index of multiple deprivation (BIMD) by municipality. The BIMD provides a multidimensional view on social deprivation in Belgium, integrating 6 domains - education, employment, income, housing, crime, and health. It provides a robust basis for assessing social inequalities in health and other outcomes. The BIMD is a relative measure of deprivation, and is computed at the level of the statistical sector, the smallest administrative level in Belgium.
