The 2014 KnightFrank World Wealth report indicates that there are 167,600 people in the world with over US$30 million in net worth and they have a collective net worth of $20.1 trillion.
High net worth individuals (HNWIs) have a net worth over US$1 million that does not count the principal residence.
At the end of 2013, there were just over 13 million HNWIs in the world. The United States of America had the highest number of HNWIs (just over 4 million) of any country.
Revisiting my wealth related predictions made in 2006 at nanotech-now.
Millionaires (HNWI 1-5 million) 20 million triple 2004 levels 2018-2020
Pentamillionaires (MNW 5-30 million) 2 million triple 2004 levels 2018-2020
Those predictions look to be on track.
