Frequently asked questions

What is the population of Thiruvananthapuram in 2026?
There is no official figure after Census 2011. Our estimate for 1 March 2026 is ≈7.9 lakh within the 2011 city limits and ≈17.8 lakh for the metro area (urban agglomeration). Both are labelled estimates (method M1).

7,43,691 within city limits (Thiruvananthapuram (M Corp.)); the Thiruvananthapuram urban agglomeration had 16,79,754; the Thiruvananthapuram district had 33,01,427.

Why do sources give such different numbers for Thiruvananthapuram?
They measure different areas. The municipal body covers the city proper; the urban agglomeration adds the contiguous towns and outgrowths around it; the district adds rural areas too. Quoting the district figure as the "city population" is the most common mistake.
