Actually tbss, aknorth was quoting the ADN issue of 14 Sept (https://www.adn.com/business-economy/2017/09/14/alaskas-median-income-ticked-up-last-year-income-inequality-went-down/). It contains "Alaska was one of just two states where income inequality decreased between 2015 and 2016...For income inequality, we've always been No. 1, 2 or 3 on the least income inequality." Getting snarky behind a fake name doesn't make your case stronger.

Plot  number of households with a given income vs household income. It's a curve, obviously, not a number. Curves for many 3rd-world countries are heavily weighted to the small incomes, with a few very large incomes (royalty, perhaps) - large income inequality. Curves for a country like Sweden are far more flat - small income inequality. This is simple data collection and you can do this for U.S. states. Arguing as to whether a particular scalar does or does not capture the essence of the curve for Qatar vs the curve for Norway is simple misdirection.
