"No continent is as small and fragmented as Europe. Only Australia is smaller, yet Europe consists of fifty independent nations...... Crowded with nations, it is also crowded with people. Europe's population density is 72.5 people per square kilometre. The European Union's density is 112 people per square kilometre. Asia has 86 people per square kilometre. Europe is crowded and fragmented."

George Friedman, Flashpoints: The Emerging Crisis in Europe (2015)
