Where The Density Of Super-Rich Individuals Is Highest
Super Rich
The analysis found that Hong Kong has an extremely high UHNWI density thanks to its status as a global financial hub, its proximity and trading links with China, along with close ties with both the U.S. and EU. Hong Kong has 1,364 super-wealthy individuals per million of its population last year while Switzerland and Luxembourg had 848 and 699 per million people respectively. The top-five was rounded off by Singapore with 530 and Ireland with 421 per million people.
Even though the U.S. is the dominant country for the super-rich, accounting for 31 percent of the total global UHNWI population, it only comes 10th in the density league with 306 per million of its inhabitants. That's just behind Denmark with 334 and Canada's 324.
