The Insane Growth Of America’s Millionaire Class
For decades, becoming a millionaire felt like an almost impossible dream — a status reserved for celebrities, Wall Street tycoons, and business moguls. In the late 1990s, shows like Who Wants to Be a Millionaire captured America’s fascination with wealth, while the dot-com boom created a new generation of “internet millionaires.”
Today, however, millionaire status is far more common than it once was.
According to Federal Reserve data, the average American household now holds a net worth exceeding $1 million for the first time ever. Estimates from UBS Wealth Management suggest the United States is home to roughly 22 million millionaire households — about one in every six households nationwide.
What Counts as a Millionaire?
A millionaire household is generally defined as one with at least $1 million in total net worth, including:
- Stocks and investments
- Retirement savings
- Real estate holdings
- Other valuable assets
…minus any outstanding debts.
Some calculations exclude primary residences, which lowers the total number of millionaire households to around 15 million — still an enormous figure compared to past decades.
Millionaires Were Once Extremely Rare
In the mid-1800s, millionaire households were almost nonexistent in America.
By 1848, only around 50 households in the entire country had accumulated fortunes worth at least $1 million — equivalent to roughly $40 million today. Many of these fortunes came from industrial commerce in cities like New York and Philadelphia, while others were tied to plantation wealth in the South.
As America industrialized during the late 19th century, wealth expanded rapidly. By the end of the 1800s, the number of millionaire households had surged to roughly 4,000 during the Gilded Age.
Stock Market Booms Helped Create More Wealth

Major waves of millionaire growth often coincided with booming financial markets.
Strong gains during the 1910s and 1920s dramatically increased wealth before the Great Depression slowed momentum. Later, periods of tax cuts and rising stock prices — particularly during the Reagan era — fueled another major expansion of affluent households.
More recently, the years between 2019 and 2022 saw one of the fastest jumps in household wealth in modern history.
Several factors contributed:
- Pandemic-era savings increased sharply
- Stock markets climbed significantly
- Home prices soared nationwide
- Many households reported unusually high income growth
During that three-year span alone, median home equity values jumped from roughly $139,000 to $201,000.
Inflation Isn’t the Only Reason
While inflation has reduced the purchasing power of $1 million, economists say the rise in millionaire households goes beyond simple price increases.
Research using inflation-adjusted dollars found:
- In 1983, about 2.4 million US households had inflation-adjusted wealth above $1 million
- By 2016, that number had climbed to 9.1 million households
Another comparison highlights the scale of change: in the early 1960s, only around 1–2 million households held wealth equivalent to $1 million in today’s dollars. Now, the total exceeds 20 million households.
Higher Incomes Also Played a Role
Rising earnings have helped fuel the expansion of wealthy households.
IRS data shows the number of tax returns reporting adjusted gross income above $1 million increased by roughly 30% between 2020 and 2022.
However, that doesn’t mean most Americans are financially secure.
Wealth Is Still Highly Unequal

Although the average household net worth now exceeds $1 million, averages can be misleading because ultra-rich households heavily skew the data.
The median household net worth in America remains far lower — approximately $193,000.
Wealth is also concentrated at the top:
- The richest 10% of households own roughly two-thirds of all US wealth
- Middle- and lower-income families still control a relatively small share of national assets
Even households whose net worth has increased may not necessarily feel richer in daily life.
The Importance of Stocks vs. Housing
One major difference between millionaires and non-millionaires is the type of assets they own.
Millionaire households typically hold large portions of their wealth in:
- Stocks
- Securities
- Investment accounts
These assets account for about 40% of millionaire wealth.
By contrast, middle-class households rely far more heavily on their primary homes, which make up roughly 65% of their net worth.
That creates important differences:
- Stock investments are easier to sell or borrow against
- Home equity is less flexible for spending or emergencies
- Housing-heavy wealth can become risky during real estate downturns
How Much Wealth Comes From Inheritance?

Inherited wealth does play a role in millionaire status — but not as much as many people assume.
Federal Reserve surveys show around 20% of American households have received some form of wealth transfer or inheritance.
Among millionaire households, inheritance is far more common:
- Roughly 45% received wealth transfers
- Inheritances accounted for about 19% of their net worth on average
Still, most millionaire wealth growth came from appreciating assets like stocks and real estate rather than inheritance alone.
Where America’s Millionaires Live Today
The geography of wealth has changed dramatically over time.
In the late 1970s, states like Idaho, Nebraska, North Dakota, and Maine ranked surprisingly high in millionaire concentration due largely to booming farmland values.
But modern millionaire populations are now concentrated mostly in coastal states and major metropolitan areas where:
- Real estate prices are extremely high
- High-paying industries dominate
- Investment opportunities are more abundant
Today’s millionaire hotspots are heavily tied to technology, finance, and professional services rather than agriculture.
Millionaire Status Doesn’t Mean Luxury Anymore

A million dollars still represents substantial wealth, but it no longer guarantees an extravagant lifestyle — especially in expensive cities.
Rising housing costs, inflation, and the growing importance of retirement savings have transformed millionaire status from a rare symbol of elite wealth into something increasingly mainstream in America’s upper-middle class.
The millionaire class has expanded dramatically, but the gap between ordinary households and the ultra-wealthy remains enormous.
Why Becoming a Millionaire Feels Different Today
Becoming a millionaire once symbolized luxury and elite status, but rising living costs and inflation have changed that reality. Today, much of a millionaire’s wealth is tied to homes, retirement accounts, and investments rather than cash. In expensive cities, a $1 million net worth may provide financial stability instead of extreme wealth, making millionaire status far more common — and less glamorous — than in previous generations.
