More unequal or less? A review of global, regional and national income inequality

Abstract

This article presents a multi-perspective discussion of trends in income inequality. Recent evidence from many sources shows that global income inequality is high and relatively stable, with the main changes being driven by developments in China and India. In developed countries, the trend has been towards higher levels of inequality over the last thirty years; and this has also been true of developing countries in the past decade, with the exception of Latin America, which is analysed here in detail. In the region, income became less unevenly distributed between 2002 and 2014, mainly because inequality within countries declined in most cases; but the latest measurements suggest that this trend is faltering.
