Using kernel density estimation we describe the distribution of household size-adjusted real income and how it changed over the business cycle of the 1980s in the United States and the United Kingdom. We confirm previous studies that show income inequality increased in the two countries and the middle of the distribution was squashed down. Using a series of statistical tests, however, we find that while the mass in both tails of the distribution increased significantly in both countries over the period, by far the greatest gains were in the upper tail.
