Using the Gini coefficient — a standard measure of inequality — GlobalPost identified pairs of U.S. metro areas and countries that have the same level of inequality. Reporters and photographers then set out to find what inequality looks like in each of these places.

These Gini coefficient comparisons are dubious. They compare a US metropolitan area’s Gini coefficient to a NATION’s Gini coefficient. So for example, Beijing is assigned China’s Gini coefficient! I am sorry, Beijing is not representative of China when it comes to income distribution. This is an inappropriate use of statistics. Just because it looks pretty does not mean it is good science.
