This article presents spatial data related to the quality of school infrastructures in the city of Mbujimayi so as to bring out their characteristics and the typology of quarters which contain these infrastructures. The variables used are presented in the spatial information matrix. The principal components analysis and factorial analysis of correspondences helped make the description of associations based on these variables. The correlation matrix gave birth to channels of the strongest positive correlations (r ≥ 0.60) and resulted in the principal component analysis. The main results are: The cartography of quarters containing schools.
