Trends of income inequality and polarisation previously were calculated by
Arshad, et al. (2008) in Pakistan for the period of 04 years from 1992-93 to 2001-02,
using Gini-coefficient and Bossert and Schworm (2006) measures respectively. Empirical
analysis of polarisation has huge importance in the economic policy making. However,
polarisation has been less probed, rather un-explored phenomenon. So far only a handful
studies have been conducted on this topic and most of the covered western countries with
an exception of India. This research area appears to be unexplored in Pakistan, except for
a few studies which led to the foundation for the present study.
