Germany Billionaire count: 137 Total wealth: $550 billion Germany is the only euro zone country to make the list of the most billionaires, bucking the trend of declining wealth in the majority of the bloc’s nations. The country’s 137 billionaires account for less than 1 percent of the ultra-high net worth group, but control nearly 27 percent of the total fortune in the segment. The ultra-rich are those that have $30 million or more in assets. German billionaires are worth $4 billion each on average, and the three cities with the maximum number of ultra-rich are Munich, Dusseldorf, and Hamburg. A nearly three percent fall in its equity market and a 13 percent drop in the value of the euro during the period between August 2011 and July 2012 did little to knock off wealth creation in Germany, according to Wealth-X. In Europe’s largest economy, the combined wealth of the ultra-rich group grew by 5.3 percent from the previous year, even as their numbers fell 1.4 percent.
