Italy is largely homogeneous linguistically and religiously but is diverse culturally, economically, and politically. Italy has the fifth-highest population density in Europe--about 200 persons per square kilometer (490 per sq. mi.). Minority groups are small, the largest being the German-speaking people of Bolzano Province and the Slovenes around Trieste. Other groups comprise small communities of Albanian, Greek, Ladino, and French origin. Although Roman Catholicism is the majority religion--85% of native-born citizens are nominally Catholic--all religious faiths are provided equal freedom before the law by the constitution.
