The variance in the logarithms of per capital GDP in purchasing-power-parity prices increased in the world from 1960 to 1968 and decreased since the mid 1970s. In the later period the convergence in intercountry incomes more than offset any increase within country inequality. Approximately two-thirds of this measure of world inequality is intercountry, three-tenths interhousehold within country inequality, and one-twentieth between gender differences in education. If China is excluded from the world sample, the decline in world inequality after 1975 is not evident. Much improved data will be required to infer with confidence the character of trends in household and gender inequality.
