"No continent is as small and fragmented as Europe. Only Australia is smaller, yet Europe consists of fifty independent nations (including Turkey and the Caucasus, for reasons explained later). Crowded with nations, it is also crowded with people. Europe's population density is 72.5 people per square kilometer. The European Union's density is 112 people per square kilometer. Asia has 86 people per square kilometer. Europe is crowded and fragmented."
