The largest province of Pakistan by population is Punjab — 127,688,922 people in the 2023 census, more than half of all Pakistanis. This page ranks all four provinces by population with census data and explains why the ranking shapes everything from elections to funding.
Quick answer: Largest province of Pakistan by population (2023 census): 1. Punjab — 127.7m (~53%); 2. Sindh — 57.9m (~24%); 3. Khyber Pakhtunkhwa — 40.9m (~17%); 4. Balochistan — 14.9m (~6%).

The 2023 census ranking
Punjab, then daylight. Punjab: 127,688,922. Sindh: ~57.9 million (Karachi alone holds ~18.9m of them). Khyber Pakhtunkhwa: ~40.9 million (boosted by the 2018 tribal-districts merger). Balochistan: ~14.9 million — fewer than many single cities. Pakistan’s total: 241.5 million, making it the world’s fifth most populous country.
The ranking has been stable for decades: Punjab has always been the most populous province. What changes is the margin — and the political fights over counting, especially Karachi’s disputed numbers. The area ranking is the mirror image: see the main guide.
The census methodology matters: the 2023 count was Pakistan’s first digital census, using tablets and GPS mapping. It was also among the most contested — the MQM-P and JI rejected Karachi’s figures, and Balochistan’s remote districts posed enumeration challenges. Population numbers in Pakistan are never just numbers.
Punjab: the demographic giant
Bigger than most countries. Punjab’s population exceeds that of all but about a dozen nations. Its density comes from the irrigated plains of the five rivers — the densest agricultural settlement in the country. Lahore (~13m+ metro), Faisalabad, Rawalpindi, Multan and Gujranwala anchor an urban network unmatched elsewhere in Pakistan.
Demography is destiny in Pakistan’s politics: Punjab elects the most National Assembly members, so the province’s vote decides governments. Every delimitation after a census is a Punjab story first.
Sindh, KP and Balochistan
The rest of the ranking. Sindh’s 57.9m is urban-heavy — Karachi’s megacity dominates, with Hyderabad and Sukkur secondary. KP’s 40.9m reflects the post-merger province: Peshawar plus the former tribal districts, a young and fast-growing population. Balochistan’s 14.9m is the paradox: the biggest land, the fewest people — a density among the world’s lowest for a subnational unit.
Growth rates differ: KP and Balochistan grow faster than Punjab and Sindh, slowly rebalancing the shares. The pillar guide tracks the trends.
Why the population ranking matters
Seats, money, water. National Assembly seats follow population (Punjab’s dominance); NFC transfers follow population-plus-other-criteria (the census fights); and development spending follows political weight. The population ranking is thus the master key to Pakistan’s federal politics — more important than the area ranking for day-to-day governance.
For students: pair this page with the phrasing guide so you answer “by population” questions correctly.
The water dimension is often missed: Punjab’s population is sustained by the Indus system, and inter-provincial water disputes (the 1991 Water Accord, the Kalabagh dam controversy) are population politics in disguise. People need water — and where the people are determines where the water arguments happen.
