Just looked into the latest wealth distribution data and it's pretty wild how concentrated money really is. Turns out the richest cities in the world have way more millionaires than most people realize.

New York's sitting at the top with around 349k millionaires and 60 billionaires. But what caught my eye is the Bay Area - 305k millionaires and actually more billionaires (68). The growth rate there over the past decade was insane at 82%, compared to New York's 48%.

Across the Pacific, Tokyo's got 298k millionaires but their millionaire population actually shrank by 5% over that same period. Beijing though? That's where it's getting interesting - 125k millionaires with 90% growth. Shows where wealth is flowing these days.

Singapore, London, LA, Paris - they're all major hubs too. London and Hong Kong both saw their millionaire populations decline slightly, which is interesting. Meanwhile Sydney and Beijing are growing. When you look at richest cities in the world by this metric, it really shows how much wealth is concentrated in just a handful of places, and how that concentration is shifting geographically.

The data's from a 2023 report, so it gives a pretty clear snapshot of where the money actually is. Most of the richest cities in the world are still in developed nations, but the growth patterns tell a different story about where future wealth might be heading.
