There are two new locales in our list of the top 10 billionaire cities: Chicago and São Paulo, Brazil, which tied for ninth place with Mumbai and Tokyo. Each of those cities has 10 billionaires in residence.
São Paulo is the only South American city in the top 10. Nearly 11 million people live in the teeming metropolis, including Joseph Safra, head of Banco Safra and Dorothea Steinbruch, who controls one of Brazil's largest steelmakers, Companhia Siderurgica Nacional.
The US has more cities in the top 10 than any other country: New York, Chicago, San Francisco, Dallas and Los Angeles.

Is forbes trying to say that Dubai or Abu Dhabi do not have even 10 billionaires ..... (Robbie G - Before you start getting all excited. I know that forbes does a seperate list for royalty, but Al Futtaim, Al Habtoor, etc should give enough weight).
