Just looked into some interesting data about how many people in the US are millionaires, and the numbers are actually pretty wild. According to Federal Reserve surveys, we're talking about roughly 18% of American households hitting that seven-figure net worth mark as of 2022. That's around 23.7 million households. And honestly, that percentage has been climbing even when you strip out inflation effects.

What caught my attention though is where these millionaires are actually getting their wealth from. It's not what most people think. Sure, everyone talks about starting a business as the path to riches, but only about 17% of millionaires have any meaningful business equity. The real wealth builders? They're doing something way more boring but apparently way more effective.

Retirement accounts are the heavy lifter here. The average millionaire has roughly $810,000 sitting in retirement savings across IRAs, 401(k)s, and similar vehicles. For those in the $1-3 million range, it's closer to $450,000. Then you add home equity into the mix, and we're looking at another $743,000 on average. That's the real wealth accumulation story nobody talks about.

What's interesting when you break down how many millionaires exist by age group is the stark difference. You've got less than 2% of 18-29 year olds hitting millionaire status, but that jumps to over 27% for people in their 60s. The median age is 62. Basically, time in the market beats timing the market, as they say.

The income side is also revealing. Median millionaire household income is around $215,000, which is solid but not insane compared to what people might imagine. For the $1-3 million crowd, it drops to $164,000. That's well above the national median of $70,000, sure, but it's also not like you need to be making half a million a year to get there.

So if you're wondering how many millionaires are actually out there and what their common traits are, the pattern seems pretty clear: start early, consistently save and invest, let compound growth do its thing over decades, and own your home. The people hitting millionaire status aren't necessarily the flashiest earners or entrepreneurs. They're just disciplined about putting money into retirement accounts and building equity over time. That's the unsexy truth about wealth building in America.
