The answer, according to Credit Suisse’s “Global Wealth in 2015” report, is 15.7 million. Compared to the U.K., the country with the next most millionaires, the U.S. has 6.5 times as many millionaires.
Of course, the U.S. also has around five times the population of the U.K., so the millionaires per capita aren’t too different—around 4.9% of the U.S. population is a millionaire and 3.7% of the U.K.
Looking at Statista’s chart, which visualized the Credit Suisse data, there is a serious exponential curve down from the U.S. to Turkey, which makes its number 15 slot look like a slap in the face rather than an accomplishment, which it is—there are 196 or 195 countries, depending on how you count.
Clearly, there’s some serious global inequality in addition to what Democratic presidential contender Bernie Sanders has been trumpeting at home.
