North Dakota was one of the leading states with new millionaires according to USA Today.

It is no doubt in large part, due to the oil industry. The state led the country when it comes to the growth of millionaires per capita last year. We added 1,800 new millionaire households bringing our millionaire ratio to 4.59% from 4% in 2012.

The big loser in terms of millionaires per capita was Nevada, which lost a whopping 8,000 millionaire households.
