The groupwise decomposition: Estimating group-specific contributions to differences between demographic measures (by Eugenio Paglino)

Background: Several general decomposition algorithms have been developed to decompose the difference between the values of demographic measures in two populations. However, fewer techniques are available to researchers wishing to understand how different subpopulations are contributing to the difference in the value of a demographic measure between the total population and a reference subpopulation. Methods: This paper proposes a general decomposition to answer these ‘groupwise’ questions. As fo
