The post The Countries With the Most Millionaires and Billionaires Around the World first appeared on Crafting Your Home.
The world’s wealthiest people are concentrated in a relatively small number of countries, but the global wealth map looks different depending on whether the focus is on millionaires or billionaires.
The United States leads both categories, with the largest population of U.S.-dollar millionaires and the most billionaires on Forbes’ 2026 list. However, the rankings reveal different stories about wealth creation, economic size and concentration.
According to the UBS Global Wealth Report 2026, which analyzes household wealth data for 2025, the United States had about 23.6 million adults with net wealth of at least US$1 million. Mainland China ranked second with about 5.3 million millionaires, followed by Japan with around 2.9 million.
For billionaires, Forbes’ 2026 World’s Billionaires list provides a separate picture, counting named individuals estimated to have a net worth of at least US$1 billion. Forbes ranked the United States first with 989 billionaires, followed by mainland China with 539 and India with 229.
The difference between the two lists highlights an important point: having the most millionaires is not the same as having the most billionaires, and neither measure alone defines how wealthy a country’s population is.
The countries with the most millionaires
The United States dominates the global millionaire rankings, supported by its large population, major financial markets, high-value businesses and significant household wealth.
UBS defines millionaires based on net wealth, which includes financial assets such as savings, stocks and bonds, as well as non-financial assets like real estate and business ownership, minus debts and liabilities.
This means a millionaire under UBS’s definition does not necessarily have US$1 million sitting in cash or investments.
The top countries by estimated number of U.S.-dollar millionaires in the UBS Global Wealth Report 2026 are:
The United States leads with about 23.6 million millionaires, followed by mainland China with about 5.3 million and Japan with approximately 2.9 million. Germany ranks fourth with around 2.6 million, while the United Kingdom and France each have about 2.4 million. Australia follows with around 1.6 million, while South Korea and the Netherlands each have roughly 1.3 million. Italy completes the top 10 with about 1.2 million millionaires.
These figures reflect total numbers rather than the share of the population that is wealthy. Large countries naturally have an advantage in total millionaire counts because of their population size and economic scale.
UBS reported that the United States, mainland China, Japan, Germany, the United Kingdom and France each had more than 2 million millionaires in 2025.

The countries with the most billionaires
The billionaire rankings tell a different story because they focus on individuals with extremely large fortunes rather than broader household wealth.
Forbes’ World’s Billionaires 2026 list counted 3,428 billionaires worldwide with combined estimated wealth of US$20.1 trillion.
The United States ranked first with 989 billionaires, reflecting the country’s strong presence in technology, finance, investment markets and large publicly traded companies. Mainland China ranked second with 539 billionaires, while India placed third with 229.
The billionaire ranking shows how ownership of major companies and business valuations can shape wealth concentration.
A country can have many millionaires because of broad household prosperity, while another can rank highly for billionaires because it has a smaller number of individuals with exceptionally large fortunes.
This explains why Japan appears among the world’s leading millionaire countries but does not rank among the top three billionaire countries. India shows the opposite pattern, ranking third for billionaires but not appearing in UBS’s top 10 millionaire countries based on the available 2025 data summary.
Why some countries create more wealth than others
The concentration of wealth across countries is shaped by multiple factors rather than one single cause.
Population size plays a major role. Countries with large populations and large economies have more opportunities to produce wealthy households and successful businesses.
Economic scale also matters because major economies tend to have deeper financial markets, more companies and larger pools of investment capital.
Asset values are another important factor. UBS’s wealth calculations include financial and non-financial assets, so changes in stock markets, property prices, and business valuations can affect millionaire counts. The report linked global wealth growth in 2025 to strong financial-market performance and rising non-financial assets.
For billionaire rankings, company ownership matters most. Forbes figures can shift as the value of publicly traded companies and private businesses changes.
Currency movements also affect comparisons because UBS measures wealth in U.S. dollars. Exchange-rate changes can affect international rankings even when local-currency wealth changes less dramatically.
Smaller countries with the highest millionaire concentration
While the United States has the largest total number of millionaires, smaller countries often rank higher when wealth is measured by the proportion of adults who are millionaires.
UBS reporting indicates that Luxembourg and Switzerland had among the highest concentrations of U.S.-dollar millionaires in 2025, with more than one in eight adults estimated to meet the millionaire threshold. Other markets with high millionaire concentration include Hong Kong SAR, Australia, the United States and the Netherlands.
This creates a major difference between wealth scale and wealth concentration.
The United States leads because of its enormous economy and population. Luxembourg and Switzerland, meanwhile, demonstrate how smaller countries can have a much larger share of wealthy residents even if their total millionaire numbers are far lower.
Average wealth does not tell the whole story
Another way to compare countries is through average wealth per adult and median wealth per adult.
UBS’s 2026 report ranked Switzerland first for average wealth per adult at US$910,382, followed by the United States at US$696,277 and Luxembourg at US$654,732. However, Luxembourg ranked first for median wealth per adult at US$394,005, followed by Belgium and Australia.
The difference between average and median wealth is important. Average wealth can be heavily influenced by extremely wealthy individuals, while median wealth reflects the wealth level of the person in the middle of the population.
A country can therefore have a very high average wealth figure without that meaning every resident has a similar level of assets.
Global wealth continued growing in 2025
The number of wealthy individuals increased worldwide in 2025. UBS reported that global personal wealth rose by 10.8% during the year, creating nearly 1 million new U.S.-dollar millionaires.
The United States accounted for almost half of the estimated increase, adding more than 440,000 new millionaires in 2025.
However, these increases do not represent people earning US$1 million in income. Wealth rankings are influenced by asset prices, investments, property values, business ownership and currency changes.

What millionaire and billionaire rankings reveal
The countries with the most millionaires and billionaires show where global wealth is concentrated, but the rankings answer different questions. Millionaire rankings highlight broader household wealth, while billionaire rankings focus on individuals with extraordinary fortunes.
The United States leads both categories, but countries such as Japan, India, Luxembourg and Switzerland demonstrate how different measures of wealth can produce different results.
The biggest economies tend to dominate total wealth rankings because of their size and financial power. Smaller countries can stand out when wealth is measured by concentration or wealth per adult.
Ultimately, no single list defines the global wealth picture. It depends on whether the focus is on the number of wealthy people, the size of individual fortunes, or how widely wealth is distributed across a population.
