The growing gap between the megamillionaire and the millionaire next door

Millionaires are just like the rest of us. Well, at least in one way: just as with the rest of the population, there’s plenty of inequality even among the richest Americans, according to a new report.

The US Wealth Report from consulting firm Capgemini and RBC Wealth Management breaks down the population of high net worth individuals — people with more than $1 million in investable assets (meaning it would include their stock portfolios but not their homes, for example). And one of the most striking findings is that ultra-HNWIs — people with $30 million and over in investable assets — control a disproportionate share of HNWI wealth compared to mid-tier millionaires ($5 million to $30 million) and what the report calls “millionaires next door” ($1 million to $5 million).

Not only that, but the population and wealth growth of the uber-rich are outpacing those of the merely very rich. The ultra-HNWI population grew by 18.6 percent between 2012 and 2013, compared to 17.5 and 16.5 for mid-tier and next-door millionaires, and wealth growth saw similar trends.

And in case you were wondering the likelihood of there being a millionaire next door to you as we speak, here’s a bonus chart from the report: the 12 cities with the most HNWIs.

Today, there are around 4 million of these millionaires in the US with combined wealth of $13.9 trillion. The number of those people grew by 16.6 percent last year, and their wealth grew by 17.7 percent — both of which are record growth rates since this survey began in 1997.
