The world’s millionaire class continues to expand in 2025, but which countries have the most millionaires per capita?

This visualization showcases where millionaires are most common relative to the adult population, offering a clearer picture of wealth density rather than absolute counts.

Data & Discussion

The data for this visualization comes from the UBS Global Wealth Report 2025, with population data (15 years and older) from The World Bank.

It measures the number of millionaires per 1,000 adults—essentially, the share of adults with a net worth above $1 million (USD).

The data table below shows the number of millionaires per capita for the 25 countries with the highest number of absolute millionaires in 2025:

This ratio provides insight into how widespread wealth is within a given society, distinguishing countries with broad-based affluence from those where wealth is concentrated among a few.

Switzerland Has the Most Millionaires per Capita

Switzerland remains the undisputed leader in millionaire concentration among the top 25 countries with the most millionaires. With 145.6 millionaires per 1,000 adults, about one in every seven Swiss adults is a millionaire.

This dominance reflects a combination of high savings rates, robust financial institutions, a strong currency, and the country’s legacy as a private banking hub.

Below Switzerland, the next group of countries—Hong Kong (96.1), Australia (85.2), and the United States (84.8)—illustrate different wealth dynamics.

Hong Kong’s high density of millionaires stems from its real estate and financial sectors and relatively smaller population, while Australia’s figure reflects widespread property ownership and strong pension assets.

The U.S. ranks highly largely due to its high overall wealth, as it’s also the country with the world’s most millionaires in 2025.

Countries With Few Millionaires per Capita

At the other end of the spectrum, countries like India (0.8), Brazil (2.5), and Russia (3.6) have the fewest millionaires per capita—with fewer than four per 1,000 adults.

Even major economies such as China (5.3) and Saudi Arabia (12.6) remain far below Western peers, despite hosting some of the world’s fastest-growing populations of high-net-worth individuals.

This disparity highlights the concentration of millionaires in developed economies, where asset ownership, stock markets, and housing values have compounded over decades.

In contrast, emerging markets still face structural challenges such as lower household savings and less mature financial systems, which limit the proportion of individuals crossing the millionaire threshold.
