The majority of Pakistan's population lives along the Indus River valley and along an arc formed by the cities of Faisalabad, Lahore, Rawalpindi/Islamabad, and Peshawar.

Although the official language of Pakistan is Urdu, it is spoken as a first language by only 9% of the population; 65% speak Punjabi, 11% Sindhi, and 24% speak other languages (Pushtu, Saraiki, Baloch, Brahui). Urdu, Punjabi, Pushtu, and Baloch are Indo-European languages; Brahui is believed to have Dravidian (pre-Indo-European) origins. English is widely used within the government, the officer ranks of the military, and in many institutions of higher learning.
