  • Hindi and regional languages are essential
  • Recruitment takes longer, so plan for it
  • Results often differ sharply from metro findings

Reader intent

Who this guide is for

Three readers arrive here with different problems. Each should be able to act on this page without reading all of it.

  • Brands expanding beyond the metros

    What changes about market sizing & forecasting once you leave the eight largest cities — in sampling, language and logistics.

  • Sales and distribution leaders

    Where the next wave of category growth sits, and how to measure it before you resource it.

  • Researchers designing for Bharat

    Design choices that keep Tier 2 and rural respondents genuinely represented, not merely counted.

01

Why go beyond the metros

Brands increasingly find their next customers in cities like Indore, Lucknow, Coimbatore and Surat. Metro-only research misses them.

02

Practical tips

  • Use native-language moderators and interviewers
  • Allow extra recruitment time
  • Supervise fieldwork closely
  • Adapt stimulus and examples to local context

03

What goes wrong

Common mistakes in market sizing & forecasting

Most disappointing market sizing & forecasting studies fail for reasons that were visible in the design, not in the fieldwork. These are the ones we see most often, and what to do instead.

  • 01

    One source, multiplied

    A single published figure extended by assumptions inherits every error in the original and adds new ones. Build two independent estimates and reconcile them.

  • 02

    Confusing the total market with the reachable one

    TAM impresses investors and misleads planners. State SAM and SOM explicitly, with the constraints that separate them.

  • 03

    Assumptions nobody can trace

    Any input without a visible source is challenged once and ignored thereafter. One assumption, one line, one source.

  • 04

    Borrowed growth rates

    A CAGR copied from a published report is a guess with a decimal point. Derive growth from drivers you can observe — households, outlets, penetration, price.

  • 05

    Assumptions buried in the model

    A number nobody can trace is challenged once and ignored thereafter. Every assumption on its own labelled line, with its source.

  • 06

    Analysis with no recommendation attached

    Senior readers need a position. Close each section with what you would do, and what would have to be true for you to change your mind.

Run through this before sign-off

Your checklist before you brief anyone

A working sequence for a market sizing & forecasting project. Most of it costs nothing, and it saves the two weeks a re-field would take.

  1. 1

    Build the estimate top-down and bottom-up independently, then explain the gap.

  2. 2

    Validate with manufacturers, distributors or regulators who see actual volume.

  3. 3

    Put every assumption on its own labelled line, with its source and date.

  4. 4

    Separate TAM, SAM and SOM with the constraint that creates each step.

  5. 5

    Scenario the three assumptions the answer is most sensitive to.

  6. 6

    Hand over a working model rather than a PDF, so the team can update it next quarter.

  7. 7

    Agree in writing who acts on each finding, and by when, before the debrief ends.
