Which State Has the Highest Percentage of Millionaires? Bet You Can't Guess. (Hint: Not New York or California)

Many people would like to be millionaires. But it ain't easy. (According to Mark Cuban, if he had to start over and rebuild his wealth, he would get a sales job.)

And many succeed: Recent statistics show that 5.8 percent of the country -- just over 7 million households -- are millionaires. In this case "millionaire" is defined as having a million dollars in investable assets so it doesn't include your home, employer-sponsored pension plans, or business partnerships.

So which states have the highest percentage -- not biggest total, but highest concentrations -- of millionaires? And which states have the lowest?

Let's find out. And while we're at it, take a look at the cost of living -- not an absolute measure, since income and sales taxes also make an impact -- for each state. 

In some cases (Hi New York!) your money goes a lot less far in relative dollars. In others, a million is worth a lot more. (Respectful nod in your direction, Mississippi.)
