Inequalities between groups have also been called “horizontal inequalities” (Stewart, 2009), because they result from group identities - as opposed to vertical inequalities that can be traced back to inequalities in incomes. It can have a polarising effect on society, isolating, alienating and increasing the likelihood of conflict. Civil conflicts resulting from an unequal distribution of resources do not spring from economic interpersonal inequality as measured by the Gini coefficient of income or consumption, but rather from a lack of social cohesion caused by inter-group inequality (Sambanis, 2005).
