This article is based on a consistent data base for GDP per capita and for population in 32 countries or group of countries from 1700 to 2030. World inequality, that had been increasing since 1700, decreased between 1992 and 2008. An increase from nowadays to 2030 is unlikely. Since 1992, the number of poors in the world has decreased for the first time in world’s history. Morevoer the number and the percentage of people in the middle class have increased dramatically. Finally there has been a change in the regional origin of the 10% most rich people in the world in favour of East Asia at the expense of the West.
