Massachusetts, Virginia, New Hampshire, Delaware and the District of Columbia all fall within the top 10. Hawaii, where 7.18 percent of households hold more than $1 million in assets, and Alaska, where 6.75 percent of households qualify, are the only two states outside the Northeast to crack the top 10.
Those high-worth households control almost three-quarters of the liquid wealth in the United States, said David Thompson, who runs the Phoenix Global Wealth Monitor.
States in the South make up the bulk of the bottom of the list. Fewer than 4 percent of households in Tennessee, Kentucky, West Virginia, Arkansas and Mississippi are worth $1 million or more. Just 3.76 percent of households in Idaho held more than $1 million in assets.
