In a report, the IMF said that over the past three decades, 53 per cent of countries had become more unequal but experiences varied widely.
Global inequality fell -- principally as India and China experienced swift economic growth -- but in wealthier countries the divide between rich and poor had broadened, the report said.
Advanced economies had seen rising inequality during periods of sluggish growth between 1985 and 2015 while poorer nations saw income disparities worsen as their economies expanded.
But, unlike other methods of redistributing wealth, education both promotes economic growth at the same time as it reduces income inequality, the report said.
