The Count
The 2023 Census Numbers
Why you’ll see three different figures — and what each means.
Pakistan’s seventh census — the country’s first digital count, with 1 March 2023 as reference date — produced three Karachi figures, and the confusion between them explains most arguments about the city’s size:
- Karachi city proper: 18,868,021 — the population within the city’s administrative limits.
- Karachi Division: 20,382,881 — the full division, including peri-urban areas.
- Karachi Metropolitan Corporation: 17,895,193 — the municipal corporation’s jurisdiction.
The 2023 count also recorded the gender split: 9,483,691 males, 8,409,017 females and 2,485 transgender persons. The census was approved by the Council of Common Interests in August 2023, and the next is constitutionally due before 2033. Total population of Karachi: the numbers explained →
2026 estimates
Censuses age fast in Karachi. Current estimates for 2026 range from ~17.8 million (conservative metro-area modelling) to 21.2 million (World Population Review’s metropolitan estimate) — the spread reflects different definitions of “Karachi” as much as different methods.

History
A Century of Explosive Growth
From fishing village to megacity in under a hundred years.
| Year | Population | What drove it |
|---|---|---|
| 1941 | ~435,000 | Pre-partition port town |
| 1951 | ~1.1 million | Partition: massive muhajir influx |
| 1972 | 3.4 million | Industrialisation |
| 1981 | ~5.4 million | Rural-to-urban migration |
| 1998 | ~9.8 million | Economic pull; Afghan influx |
| 2017 | 14.9 million | Continued migration + natural growth |
| 2023 | 18.9 million | Digital census count |
| 2026 | ~21.2 million (est.) | Metro-area estimate |
Karachi grew at 4.2% a year between 2017 and 2023 — roughly doubling every 17 years at that pace. In 1947 it was Pakistan’s first capital and a city of a few hundred thousand; today it holds more people than many countries.

Karachi’s 7 Districts
How the megacity is divided.
Karachi Division comprises seven districts: Karachi East, Karachi West, Karachi South, Karachi Central, Malir, Korangi and Keamari. Each has its own deputy commissioner, but the city’s governance is famously fragmented — the mayor, the cantonment boards, the DHA, the port authorities and the provincial government all control pieces of the same city, a division of power Karachiites blame for the city’s chronic infrastructure problems.
Karachi is the capital of Sindh province — see our Sindh guide — and the long-running demand to make it a separate province is covered in the Karachi province movement’s history.
People
Who Lives in Karachi
The most ethnically diverse city in Pakistan — by design of its history.
No Pakistani city is as mixed as Karachi. The 1947 Partition made it a muhajir (Urdu-speaking migrant) city; decades of internal migration added Pashtuns (Karachi has one of the world’s largest Pashtun urban populations), Sindhis, Punjabis, Baloch, Memons, Bohras, Ismailis and others. Urdu is the lingua franca, but Pashto, Sindhi, Punjabi, Balochi and Gujarati are all widely spoken.
The American scholar Stephen P. Cohen once observed that if Karachi’s ethnic groups “got along well, it would be an amazingly complex city, a lot like New York” — a compliment that doubles as a diagnosis of the city’s communal tensions. Religiously, the city is overwhelmingly Muslim, with significant Christian, Hindu and Parsi minorities.
Drivers
Why Karachi Keeps Growing
Three forces, all still running.
Jobs. Karachi generates a huge share of Pakistan’s GDP, tax revenue and industrial output — the port, the stock exchange, the factories and the services economy pull migrants from every province.
The port. The Port of Karachi and Port Qasim handle the overwhelming bulk of Pakistan’s trade; the entire logistics economy — trucking, warehousing, clearing — is Karachi-based.
Natural growth. With a young population and high fertility, Karachi grows from within as well as from migration — roughly 19,000 births a day nationally, a large share in the city.
The cost of growth is visible: water shortages, traffic, informal settlements (katchi abadis) housing millions, and infrastructure perpetually behind the population curve.
