Just checked out this wealth distribution report and got curious about where all the millionaires actually are. Turns out New York City and the Bay Area are still crushing it - NYC alone has like 384,500 millionaires, which is kind of insane when you think about it. Bay Area's not far behind with 342,400. Pretty wild that the US claims 22% of the top 50 cities for millionaires globally.

What's interesting is the growth rates though. If you're asking which city has the most millionaires, it's obviously NYC, but the real story is how fast some other places are catching up. Dubai jumped 102% in millionaire count since 2014, Shenzhen hit 142% growth - these cities are absolutely exploding with wealth. Meanwhile London actually lost 12% of its millionaire population, which caught me off guard.

The Asian cities are wild too. Tokyo's got 292,300 millionaires despite only 4% growth, Beijing and Shanghai are quietly building massive wealth bases. If you're wondering what city has the most millionaires outside the US, Tokyo's your answer. But honestly, the wealth concentration is shifting - the next decade might look totally different from this ranking. The cities with the highest growth rates are where the real action is happening.
