OK, so i've been awake for too long but peep this:
#
http://www.google.www world population
6,692,030,277
#
http://en.wikipedia.org/wiki/Millionaire
Percentage of regional population:
0.15%
6,692,030,277 * 0.0015 = 10,038,045 millionaires in the world
6,692,030,277 / 10,038,045 = 1 in 666.6666942616814
Is my math off or is this number a bit creepy?
