A third of the world's billionaires are concentrated in just 16 cities, according to a new study. 

Wealth-X's annual Billionaire Census tracks where they live, how they make their money, and more.

Here, the 16 cities across the globe with the most billionaires, from Istanbul to Moscow.

About 27 million Americans moved in 2022, according to census data. 

As for billionaires? They tend to stay put.

Almost a third of the world's billionaires are concentrated in just 16 cities, according to a new analysis of the habits and patterns of the richest individuals.

Wealth-X's Billionaire Census found that 29% of the globe's 3,194 wealthiest people, whose collective net worth totals $11.1 trillion, live in the same handful of metropolises in 2022 as they did during the last several years. 

New York City remains home to the most billionaires with 136, said the report, released Wednesday.

Other hot spots for high-net-worth folks are located across Asia, America, and the Middle East. Most of the top cities are consistent in their billionaire populations, gaining or losing one or two each between 2021 and 2022 — except for Singapore, which gained four of the world's wealthiest over the same time period.

The number of billionaires across the globe, however, dropped 3.5% in 2022 thanks to what the study authors called "a new war in Europe, a generational surge in inflation, and deepening US-China tension." People tied to industries including tech, retail, energy, healthcare, and transportation saw their average wealth decline by more than 5% in 2022.

Still, the report added, "the billionaire class wields a significant and still-growing influence over the global economy."

So let's take a tour of the 16 cities the most members of the world's wealthiest population call home.
