Following a year-long period of exceptional volatility in 2008, the world's population of high net worth individuals (HNWIs(1)) was down 14.9 percent from the year before and the population of ultra high net worth individuals (Ultra-HNWIs(2)) fell 24.6 percent, according to the 13th annual World Wealth Report, released by Merrill Lynch Global Wealth Management and Capgemini. The decrease in population was matched by a 19.5 percent drop in HNWI wealth to $32.8 trillion. The unprecedented declines wiped out two years of robust growth in 2006 and 2007, reducing both the HNWI population and its wealth to below levels seen at the close of 2005.
