Which countries have the highest percentage of millionaires today?

Who wants to be a millionaire?

For many of us, having millions in the bank is a dream. But for some lucky individuals, that financial fantasy is a reality. Swiss multinational investment bank UBS estimates that almost one million new millionaires were created in 2025. But where in the world are they likely to call home?

Click or scroll on to discover which countries boast the highest percentage of millionaires in their adult population today, according to the latest UBS Global Wealth Report.

Millionaire status measured in US dollars. Data published in June 2026. All dollar amounts in US dollars.

Italy: 2.5% of adults

Around 1,235,000 millionaires are living la dolce vita in Italy, according to UBS. That's about 2.5% of the adult population. While Italy ranks at the bottom of our list for its share of millionaires, the European nation ranks disproportionately high when it comes to billionaires.

According to Forbes, Italy has the sixth-highest number of billionaires worldwide, with crypto businessman Giancarlo Devasini the richest of them all, with an $89 billion fortune. Second is chocolate and confectionery king Giovanni Ferrero, who's worth $46 billion.

Spain: 2.8% of adults

Spain is home to 1,077,000 millionaires. This means approximately 2.8% of the country's adult population has at least seven figures in their bank account. 

According to UBS, Spain added 33,000 millionaires in 2025, with one in 670 of the country's residents joining the seven-figure club.

Japan: 2.8% of adults

In 2021, an estimated 3,224,000 millionaires lived in Japan, the third-highest amount after the US and China. At that time, 3.2% of the adult population held millionaire status, and 5% of the world’s wealthiest people resided in the Asian nation.

Fast-forward to 2025, the latest full year for which data is available, and the situation looks a little different. It's now home to 2,902,000 millionaires, a drop of over 300,000. However, Japan has regained third place in the total number of millionaires. Slow economic growth and a shrinking population are cited as reasons for the overall drop.

South Korea: 3% of adults

South Koreans are getting richer at a faster rate than anyone else in the world, with average per-adult wealth surging over 55% since 2020. However, the median rate, which better reflects the typical adult's wealth, grew by only 12% over the same period.

The country now has 1,317,000 millionaires, with roughly 3% of the adult population enjoying seven-figure status, up sharply from 1.8% in 2015.

Germany: 3.8% of adults

Germany has 2,648,000 millionaires, which equates to around 3.8% of its adult population. This marks a fall from 2,880,000 in 2021, but the country is still the leading European nation when it comes to the total number of millionaires.

It also ranks highly in terms of billionaires, with 212 ultra-rich citizens securing Germany fourth place globally.

Taiwan: 3.9% of adults

Taiwan plays host to 772,000 millionaires, down from 869,210 in 2021. That means around one in 25 of the nation's adults have a bank balance of at least seven figures.

While its millionaire population may be waning, Forbes recently reported that the country's 50 richest people have seen their fortunes surge thanks to massive demand for AI chips and tech manufacturing.

UK: 4.5% of adults

The UK's millionaire population has taken a hit in recent years: just 4.5% of British adults (2,428,000 people) had seven figures to their name in 2025, down from 5.4% in 2021. 

The UK added 43,000 millionaires in 2025 and remains one of the world's top countries by total millionaire count (it's currently in fifth place just ahead of France). However, the nation's millionaire population is now growing much more slowly than in many Eastern European countries.

France: 4.6% of adults

In 2021, France had 2,796,334 millionaires, the equivalent of 5.6% of the adult population. By the end of 2025, that number had fallen to around 2,388,000 millionaires, representing 4.6% of the country's adults.

Several factors have been cited as contributing to the decline, from the nation's political instability to wealthy individuals moving to more tax-friendly destinations.

Ireland: 4.8% of adults

Around 4.8% of Irish adults are millionaires, a total of 192,000 people. However, the country is one of the most unequal in Europe when it comes to wealth.

The charity Oxfam reports that the number of super-rich residents in the Emerald Isle has more than doubled in the last decade, with the richest 1% of Ireland's population holding more than a third of the nation's wealth.

Canada: 6% of adults

UBS doesn't include the number of Canadian millionaires in its 2026 Wealth Report, though its 2025 edition puts the figure at 2.1 million. That's around 6% of the adult population.

Meanwhile, Forbes ranks the country seventh globally for billionaires. 82 of them call Canada home, roughly 2.4% of the world's billionaire population.

Belgium: 6% of adults

Ranking higher than neighboring France, Belgium has a comparatively small number of millionaire residents, around 556,000. However, as a percentage of its much smaller adult population, this accounts for a solid 6%.

Belgium also has the second-highest median wealth figure in the UBS report at $277,166, suggesting wealth is more evenly shared among the population.

Sweden: 6.1% of adults

Sweden consistently ranks among the world's happiest nations, and for 6.1% of the Nordic country's adult population, their seven-figure bank balance is no doubt a contributing factor. 

The country now boasts 507,000 millionaires, although its share of the adult population with assets of $100,000 or more is among the lowest in the UBS report, making it one of the most unequal nations in the round-up.

Australia: 7.9% of adults

Australia boasted a staggering 2,176,868 millionaires in 2021, the equivalent of 11.2% of its adult population. However, there's been a sharp dip in recent years, with UBS recording a significantly reduced, yet still impressive, 1,634,000 millionaires Down Under in 2025.

There are various theories as to why Australia's millionaire population has shrunk, with possible factors including rising interest rates and currency depreciation against the US dollar.

Norway: 8% of adults

​Unlike other countries, Norway has seen a steep increase in its millionaire population in recent years. In 2021, 5.6% of Norwegian adults had at least $1 million in the bank; in 2025, the figure stands at 8.2%.

Meanwhile, the country's average and median wealth figures remain closely aligned, suggesting a relatively equal distribution of wealth compared to some nations in the round-up.

Denmark: 8.1% of adults

A whopping 8.5% of Danes had at least $1 million to their name in 2021, and while that figure has since dipped, it remains strong at an impressive 8.1%.

Despite its large millionaire population, Denmark has one of the lowest levels of wealth disparity in the world, which repeatedly contributes to its high ranking in the World Happiness Report. The nation ranked third in the most recent index.

Netherlands: 8.8% of adults

Almost 9% of the adult population of the Netherlands is a US dollar millionaire, with the nation currently boasting 1,294,000 of them, making it the ninth-highest globally by total millionaires.

The nation is much lower down the list when it comes to billionaires, though, and is currently home to just 14.

USA: 8.8% of adults

Everything is supersized in America – and that includes its population of millionaires. The USA was home to a staggering 23,627,000 of them in 2025, which represents almost 9% of its adult population and around 40% of all millionaires worldwide. 

Unsurprisingly, America also has more billionaires than any other country, with 989 of them currently residing Stateside, according to Forbes. Among them is Elon Musk, whose fortune briefly passed the trillion mark in 2026.

Hong Kong: 10% of adults

Roughly one in 10 Hong Kong residents could call themselves millionaires in 2025, with the region counting 628,000 of them. It also boasts one of the highest shares of adults with assets exceeding $100,000 US dollars, at close to 70%.

Meanwhile, mainland China counts 5,305,000 millionaires among its ranks, although given its vast population, your chances of bumping into one are much slimmer, with well under 1% of adults enjoying millionaire status.

Switzerland: 13% of adults

Although Switzerland accounts for just 0.1% of the world's population, its generous tax laws, which contribute to Switzerland's reputation as a tax haven, make it a highly desirable location for the super-rich.

The country had 944,000 millionaires as of 2025, with 13% of the adult population in that bracket. That same 13% also holds about 69% of Switzerland's total wealth, according to UBS.

Luxembourg: 16% of adults

Tiny Luxembourg has the highest concentration of millionaires per capita, with almost one in six adults holding seven-figure fortunes. As of 2025, 85,000 millionaires call the grand duchy home.

It also tops the chart for median wealth, which currently works out at $394,005 per adult. That said, the cost of living there is painfully high, with one in five households struggling to make ends meet, according to recent figures from the country's Chamber of Employees.
