Abstract: In this paper three important inequality measures with convenient decomposition properties are used to compare trends in intercountry inequality in two measures of well-being, namely, the Human Development Index and real income (measured by real GDP per capita in 1985 international dollars). To this end, internationally comparable data on the two measures of well-bieng for the years 1960, 1970, 1980, and 1992 are used. The results indicate that despite the near perfect positive correlation between the two measures of well-begin, the intercountry inequality trends are different, with inequality in HDI exhibiting a downward trend over the four years and that in real income exhibiting an inverted U-curve pattern.
