In 2018, 2.88 billion adults worldwide had a net worth of less than 10,000 U.S. dollars. This is in comparison to 47 million adults who had a net worth of more than one million U.S. dollars in the same year.
The distribution of wealth is an indicator of economic inequality. The United Nations says that wealth includes the sum of natural, human, and physical assets. Wealth is not synonymous with income, however, because having a large income can be depleted if one has significant expenses. In 2018, 1,391 billionaires had a total wealth of more than one to two billion U.S. dollars. The rise of wealth across the world has had an impact on the lower income populations, since economic mobility has therefore become harder to achieve.
China had the most billionaires in 2018, with the United States following closely behind. In that same year, within China and the world, Beijing was the city with the most billionaires. In 2018, North America was the region with the most amount of wealth, and in the United States, New York was the state with the greatest number of billionaires.
