The resulting Kingdom of Afghanistan was and remains ethnically, linguistically, and religiously diverse. Today, Pushtuns are the largest ethnic group within the country, but they represent only 38 percent of the population. An almost equal number of Pushtuns live across the border in Pakistan's Northwest Frontier Province. Ethnic Tajiks comprise one-quarter of the population. The Hazaras, who generally inhabit the center of the country, represent another 19 percent. Other groups -- such as the Aimaks, Turkmen, Baluch, Uzbek, and others comprise the rest.
