The report finds that since the early 2000’s, on average, wage inequality, which compares the wages of high and low wage earners, decreased in many countries at an average rate that ranged from 0.5 to 1.7 per cent annually, depending on the measure used. The most significant decreases occurred among low-income countries where the average annual decrease ranged from 3.2 to 9.6 per cent in the past two decades.
