Pakistan has a population of around 235 million — the fifth most populous country in the world — with a very young demographic: well over half the population is under 30. It is an intensely diverse country, divided by language, ethnicity, class, and geography in ways that a first-time visitor may find surprising.
The largest group is the Punjabis, who make up roughly 45% of the population and dominate the political and military establishment. Pashtuns (around 15%) live mainly in Khyber Pakhtunkhwa and the tribal belt; their culture places a high value on hospitality and personal honor, and a Pashtun host can be almost insistently generous. Sindhis populate the south and have a culture of their own — Sufi music and devotion runs deep here, and the shrines of saints like Lal Shahbaz Qalandar draw enormous crowds. Baloch people inhabit the vast southwestern province of Balochistan; they are the smallest of the major groups despite living in the country's largest province by area. In the north, Gilgit-Baltistani peoples — speaking Shina, Burushaski, Wakhi, and Balti — are culturally and linguistically distinct from everyone else.
Urdu is the lingua franca that ties the country together, but it is the mother tongue of only about 8% of the population — mainly Muhajirs, the Muslim refugees who came from India after partition in 1947 and settled largely in Karachi and other Sindhi cities. English functions as the language of government, higher education, and the urban elite.
Pakistan is a predominantly Muslim country and Islam shapes the rhythm of daily life — prayer times, the fast of Ramadan, the festivals of Eid. Within Islam, the country holds a complex sectarian mix of Sunni and Shia Muslims, Sufi traditions, Ahmadis, and smaller groups. The Kalash people of Chitral are a notable exception — a small non-Muslim minority with their own ancient religion, language, and customs who have managed to preserve their culture against the odds.
Hospitality is not a cliché here. Pakistanis will invite strangers to eat with them, insist on paying the bill, and go to considerable inconvenience to help a traveler who looks lost. This can feel overwhelming, but it's genuine.
