The U.S. was the only country of the nine largest to see a rise in either its billionaire population in 2016, according to the study.
In fact, the total net worth of all American billionaires rose to $2.6 trillion, which is equivalent to the combined billionaire wealth of Europe and the Middle East.
The census explains that the increase in American billionaire net worth was "buoyed by a stronger dollar and a robust tech sector."
Overall, the census notes that 2016 was a "challenging one for the global billionaire population." The total number of billionaires dropped by 3.1 percent to 2,397. Their combined wealth was also affected: It dropped by 3.7 percent to $7.4 trillion dollars.
This global decline occurred against a "backdrop of heightened geopolitical instability," the census explains, and also "shows a loss of momentum in recent wealth creation."
