PHOENIX - The number of millionaires in Arizona dropped slightly last year, according to the Wall Street Journal's analysis of an annual ranking by Phoenix Marketing International.
In 2013, millionaires made up 4.4 percent of Arizona's population, with 108,682 residents earning more than $1 million. The percent of millionaires in the previous year was just over 5 percent. The state ranks 34th overall.
Across the U.S., the millionaire population grew, adding 53,000 more households and totaling 6.15 million overall. Maryland boasted the highest percentage for the third year in a row with 7.7 percent.
The state of North Dakota showed the biggest leap, up 14 spots since last year, thanks in large part to a booming energy industry.
