Of the 2,604 billionaires in the world, 105 of them live in New York City. That puts New York ahead of any other city around the globe and even ahead of almost every country, with the exception of China and Germany, data firm Wealth-X reports in its 2019 Billionaire Census.

Hong Kong has the second-highest total of billionaires, with 87, and San Francisco comes third with 75.

"San Francisco is the clear leader when it comes to billionaire density," Wealth-X notes. The tech hub has one billionaire for approximately every 11,600 residents, while NYC has one for every 81,000 inhabitants.

Los Angeles also cracked the top 10 cities for billionaires worldwide, coming in seventh with a billionaire population of 39.

In general, "billionaires are increasingly congregating in a cluster of cities," Wealth-X reports, adding: "The top 15 billionaire cities accounted for almost 30% of the global billionaire population in 2018, with a total of 773 billionaires."
