Karachi’s 2026 Population Estimates
- 21,243,390 — World Population Review’s 2026 metropolitan-area estimate (updated September 2026).
- ~17.8 million — a modelled metro estimate (early 2026), with a likely range of 17.4–18.2 million.
- 18,868,021 — the 2023 census count (city proper), now three years old.
All are defensible; none is a fresh count. The next census is constitutionally due before 2033. The census numbers explained →
Why the Estimates Differ
Three reasons: definitions (city limits vs division vs metro area vs “urban agglomeration” — each draws a different boundary); methods (some project from the 2023 census with growth rates, others model migration and births); and Karachi’s informality — millions live in katchi abadis (informal settlements) that are hard to count precisely. A 15–20% spread between estimates is normal for a city like Karachi.
The Best Current Figure to Use
For most purposes: “over 21 million (2026 estimate; 18.87 million in the 2023 census)”. Cite the census for official precision, the estimate for currency — and always label estimates as estimates. In crores: ~2.1 crores.
The Trend: Still Accelerating
Karachi grew 4.2% annually between 2017 and 2023. At that pace it adds roughly 800,000 people a year — a new Faisalabad-sized population every five years. Drivers: migration for jobs, the port economy, and natural growth. The full story is in our complete Karachi population guide.
