For the past twenty years, reproductive health has been a top priority for the developing countries. In Senegal and in The Saint-Louis department, undeniable progress has been achieved but some statistics remain bleak and health inequalities, far from decreasing tend to grow. When we look closer at these disparities over the studied region, one can observe particular configurations with layouts highlighting spatial splits which go beyond the known urban/rural divide. From now on urban areas and villages share the same sanitary concerns, while rural communities gradually acquire equipment and new habits previously reserved for towns. To understand and estimate the territorial reproductive health inequalities in order to get them to decrease, such is the goal of this study.
