Wealth-X releases its annual list of the cities with the most high-net-worth individuals: Osaka and Mexico City—who knew?

Those are two surprises to come from Wealth-X’s list of the top 10 cities with the highest concentration of ultra-high-net-worth individuals.

Research firm Wealth-X, which covers the ultra-wealthy space (which it defines as total net assets of $30 million), lists four American cities as well.

The four American cities make up nearly half of the top 10 list with a combined total of 20,485 ultra-wealthy individuals.

Latin America has their share of the ultra wealthy but no cities in the top 10. The region has a total of 14,150 ultra wealthy individuals.

The top 10 cities collectively grew in their wealthy populations by a combined 7.5% over the past year, outpacing the global average of 6.3%. There are 45,230 ultra-wealthy individuals concentrated in these cities, equal to 23% of the world’s ultra-wealthy population.
