Every other country in the top 15 of millionaires for 2013 is scrunched in under Switzerland. But that's a neat little uptick there for the United States. And: China.
In fact, only China saw larger growth in its millionaire population between 2012 and 2013 than the United States.
Japan's decline and China's surge means that the ostensibly socialist country is now home to the second-most millionaires in the world. On a per-capita basis, of course, it drops off the radar. The country with the most millionaires compared to its population is Qatar, followed by Switzerland. The United States is seventh.
Boston Global also tracks the number of ultra-high-net-worth households -- those with more than $100 million in private wealth. The U.S. leads that, too, with 4,754 — up from 2,989 in 2010. China has 983 households with that much wealth, but that's up 83 percent from 2010.
Socialism is surprisingly good at capitalism, it seems.
