The degree of inequality indicated by those state-level Gini coefficients is just staggering. If New York state was considered as its own country, it would be the 12th most unequal in the world, just outpacing Colombia.
Also, this state-level data shows that the common attempt to deny inequality in the US is plain wrong. Critics try to say that other countries have lower inequality because they have fewer people and because the US has big differences in cost of living. These stats say nope to that. Every single state has a Gini of over 40%, compared to 30.8% for the EU as a whole, and into the mid-20s for the most equal first world countries.
