Evaluation of Asian Income Distribution and Poverty Ratios Using Worldwide Income Distribution

This paper aims to estimate worldwide income distribution for multiple years, and then to use this data in evaluating income distribution for particular countries or areas. Based on previous contributions to estimate the worldwide distribution for a particular year, worldwide income distribution was estimated by using per capita GDP, purchasing power parities of the International Comparison Programme, and income distribution data for various countries. Results for four years show that Gini coefficients exceeded 0.5 and were relatively stable from 1962 to 1985. Income distribution for the Asian area is compared to worldwide income distribution. A Relative Advance Index is proposed to measure the position of a country's particular income distribution in relation to worldwide income distribution. The Index shows that Asian income distribution has shifted toward higher income as compared to worldwide income. The paper also suggests that worldwide income distribution can be used to determine the poverty level cutoff point.
