8.7 Million Millionaires in the World

From The Economist:

There were 8.7m people with liquid financial assets of more than $1m in 2005 and whose total wealth reached $33.3 trillion, according to a report by Merrill Lynch and Capgemini. Two-thirds of these “high net-worth individuals” are in North America (2.9m) and Europe (2.8m); most of the rest (2.4m) live in the Asia-Pacific region.

With a little over 6 billion people that makes .15% of the world millionaires.
