Sources & evidence

Where all of this comes from.

Nagrik does not produce data. It collects the records Delhi’s civic bodies already publish — tenders, ward boundaries, officers’ directories — and puts them on one map. Everything below is a public record. This page says exactly which one, and what to do when we get something wrong.

What we take, and from where

How current it is
  • Tenders and officials refresh nightly. Boundaries are updated when redrawn.
  • Awards, cancellations and retenders follow the published portal results.
  • Tenders removed from the portal are marked closed and retained.
What we will not do

We never invent a record to fill a gap. Where an authority does not publish something — a councillor’s phone number, a ward’s zone — Nagrik shows nothing rather than a plausible guess. A blank means the government has not published it, not that we forgot to look.

Officials’ contact details

Nagrik republishes the names, designations, office phone numbers and official email addresses that these bodies already publish in their own public directories. These are official points of contact for public duties, reproduced so a resident can reach the person accountable for their ward. No personal or private contact information is collected, inferred, or shown. If you are named here and want your entry corrected or removed, write to us.

Get something corrected

Wrong number, wrong ward, wrong name, a work attributed to the wrong agency — tell us and we will fix it, or explain why the record says what it says.
