Gini coefficients were computed for a more accurate picture of income inequality
in the rural and urban areas and the respective values found to be significantly different -
0.5046 and 0.34869. The Gini coefficient can be expressed as a ratio of two regions defined
by a 45-degree line (line of perfect equality) and a Lorenz curve. The Lorenz curves for
both sectors are shown in Figure 3. Let A denote the area between the 45-degree line and
the Lorenz curve and A+B be the whole area below the 45-degree line or ½ of the unit box.
9 Urban inequality would certainly be higher if the “floating population” (migrant workers) would have been
included.
