Comparing Inequality of Income Distribution between Fars Province and the Whole Country

This paper tries to calculate and compare the trend of costs inequality between Iran’s Fars Province and the whole country in two categories of rural and urban regions within 1981-2008. Therefore, inequality indicators, i.e. Gini coefficient and income groups share, are estimated by nonparametric method. The results of studying the income distribution trend, i.e. Gini coefficient calculated from the detailed household cost-income statistics, and testing the hypotheses show that statically there is not a significant difference between the amount of economic inequality of Fars Province rural-urban regions and that of the whole country. But these calculations by Gini coefficient resulted from gross individual costs data indicate a significant difference between rural-urban regions of Fars Province and the whole country. This means that (in the latter case) the inequality of rural-urban regions of Fars Province is less than that of the rural-urban regions of the whole country. In contrast, income distribution in both the rural and urban regions of the province was the same
