In this paper we explore dierent ways to obtain decompositions of rank-dependent indices of socioeconomic inequality of health, such as the Concentration Index. Our focus is on the regression-based type of decomposition. Depending on whether the regression explains the health variable, or the socioeconomic variable, or both, a dierent decomposition formula is generated. We illustrate the dierences using data from the Ethiopia 2011 Demographic and Health Survey (DHS).
