Thus polarisation measures have properties that are notably different from inequality measures, like the Gini coefficient (Jayadev and Reddy, 2011). A well-known example of this type of fractionalisation is South African income distribution, which is highly polarised by race (Figure 4.8). Equivalised African and Coloured incomes overlap very little with those of Whites. Only the Asian/Indian distribution, which is numerically very small and heterogeneous, overlaps widely with the other three races’ distribution.
