Global billionaires boom to new record, USA leads pack

The U.S. accounted for 29% of the global billionaire population and 37% of cumulative billionaire wealth in 2020

Billionaires are booming all over the globe but the United States holds the crown for the most dynamic growth and significant wealth gains. 


According to Wealth-X's 2021 billionaire census, the total number of billionaires in 2020 jumped 13.4% year-over-year to 3,204 individuals. The figure marks the strongest annual growth since 2017, despite the impact of the COVID-19 pandemic and the deepest contraction in world economic output in a generation. Together, their combined wealth hit $10 trillion, a year-over-year increase of 5.7%. 

The United States is the most dominant country for billionaire growth, accounting for 29% of the global billionaire population and 37% of cumulative billionaire wealth in 2020, followed by China with shares of about 13% and Germany with shares of about 5%. 

Out of the total 3,204 individuals, 670 of them were new billionaires with a median wealth of $1.9 billion and $1.4 billion, respectively. 

Approximately 60% of the overall billionaire population in 2020 were completely self-made, compared to 11% who made their fortunes through inheriting money and 28.8% who made their fortunes through a combination of inheritance and self-made wealth creation. 

For new billionaires, roughly 70% are self-made, compared to 7.4% who inherited their fortune and 22.4% who have a combination of inheritance and self-made wealth creation. 

In the United States, 66.6% of billionaires were self-made, while 14% made their fortunes through inheritance and 19.3% made their fortunes through inheritance and self-made wealth creation.


In North America alone, the number of billionaires grew by 17.5% year-over-year to 980 individuals, equivalent to a 31% global share. Meanwhile, the collective net worth of the region's billionaires rose by 8% to $3.8 trillion, or a global share of 38%.  

The total number of billionaires with wealth in the range of $10 billion to $50 billion saw the strongest growth in terms of both population and combined net worth, growing by 40%, or three times faster than the growth of the overall billionaire population. 

The expansion was driven by wealth generation in the automotive, technology, materials and shipping and distribution industries. In addition, the hospitality and entertainment sector gave a boost to the total number of billionaires with wealth of more than $50 billion. 

However, the banking and finance sector remained the top industry for overall billionaire representation.
