And their combined population exceeds the U.S. by 18 million people.

Via Weekly Standard:

As the chart shows, America’s debt is currently $15.1 trillion, while the Eurozone (which includes France, Germany, Greece, Italy, Spain, the U.K., and others) has a combined debt of $12.7 trillion. (All dollar amounts are in U.S. dollars, and the data refers to closing 2011 numbers.)

The Eurozone is larger than the United States, so America’s debt per capita also exceeds the Eurozone’s. According to the Census Bureau, the U.S. has a population of 313 million, whereas the Eurozone has a population in excess of 331 million.
