When it comes to where millionaires live in America, the rich keep getting richer.

Market research firm Phoenix Marketing International notes that although the total number of millionaire households rose for the 11th straight year in 2019, the gains were disproportionately seen in states that already had more than their fair share of millionaires.

"While the total number of high-net-worth households grew, these increases were largely seen in the wealthiest states, reinforcing the broader ongoing wealth-gap issues the country faces," says Carl Uttaro, VP of financial services research at Phoenix MI.

How Many Millionaires Are in the U.S.?

Phoenix MI is tracking the effects of the coronavirus pandemic, which could make for a very different landscape going forward. But last year, at least, the good times continued to roll. Indeed, a record 6.71% (or 8,386,508 out of 125,018,808 total U.S. households) can now claim millionaire status. That's up from 6.21% in 2018 and just 5.81% in 2017.

Note well that to be considered a millionaire by the standards of wealth research, a household must have investable assets of $1 million or more, excluding the value of real estate, employer-sponsored retirement plans and business partnerships, among other select assets.

Although California and New York have a great deal of millionaires in terms of raw numbers, they don't have the highest concentrations of rich households. It turns out there are numerous states with higher percentages of well-off households, several of which probably will surprise you.

And don't forget that between living costs and taxes, a million dollars goes much further in some states than others.
