A map from the Martin Prosperity Institute charts the top 30 global cities of the super-rich, which identifies the location of high-net-worth-individuals with $30 million or more in assets each. At present, only 185,835 people currently qualify, or .003 of the global population. One-third of them are in the United States. A slightly smaller number is in Europe. A slightly smaller number still is in Asia. Check out the map for where the HNW crowd lives; not surprisingly, it is where there are plenty of other HNW prospects as well.
