Moreover, we demonstrate the existence of a critical interval of the sensitivity parameter values (v) of the extended Gini coefficient, within which the second polarization curve can be consistently expressed as the subtraction of the within-groups inequality component from the between-groups inequality component. This critical interval is defined by v ϵ[2, 3]. This approach has the conceptual advantage of viewing inequality and polarization within the same framework.
