Just looked at some interesting data on where millionaires are actually clustering globally. Turns out the US is way more represented than I thought - 8 out of the top 20 fastest-growing wealth hubs are American cities. Florida's showing up twice on the list, which caught my attention. West Palm Beach has around 11,500 millionaires with 112% growth over the past decade, and Miami's even bigger with nearly 39,000 millionaires and 94% growth. That's serious wealth concentration happening there. Texas is basically dominating though - Scottsdale, Austin, Dallas, Houston all made the cut. The Bay Area still has the largest millionaire population by far at over 342,000, but some of these newer hubs are growing way faster percentage-wise. Shenzhen in China hit 142% growth, which is wild. Anyway, if you're wondering where money's actually flowing and accumulating, this data gives you a pretty clear picture. Makes you think about which cities are becoming the next major wealth centers.
