Market sizing in a data-poor country: how we research Laos

THE SHORT ANSWER

In a market with thin official data, you size it by triangulation: a bottom-up build from observable units, a top-down check from regional benchmarks, and validation from people inside the market. One method is a guess. Three converging is an estimate.

The three routes to a number

Bottom-up

  • Count what is countable: outlets, rooms, permits, imports
  • Multiply by observable prices and volumes
  • The most defensible route

Top-down

  • Start from regional benchmarks per capita
  • Adjust for income and habits
  • A sanity check, never the answer

Network validation

  • Suppliers, landlords, operators see demand daily
  • Asks about behaviour, not opinions
  • Where a local network earns its keep
THREE ROUTES, ONE MARKET - ILLUSTRATIVE CONVERGENCE
Top-down estimate
$12m
Bottom-up build
$9m
Network-informed view
$10m

Illustrative. The honest answer is the range where routes converge: here, roughly $9-12m, stated as a range.

What we do and do not do

Vientia market research is desk research plus our local network: economic overview, competitors, prices and demand, delivered as a report with sources and stated confidence levels. We do not run focus groups or field surveys, and we say so up front: in a market this size they mostly produce expensive noise.

The rule that keeps research honest

Every number carries its source and its confidence. "Roughly $10m, medium confidence, three converging estimates" is worth infinitely more than "$11.4m" with no trail. False precision is how bad decisions get dressed up as informed ones.

Common questions

How do you size a market with no official data?

Triangulate: build bottom-up from observable units, cross-check top-down from regional benchmarks, and validate through people who see the market daily. Where estimates converge, you have a number you can use.

Is desk research enough for Laos?

Desk research plus a local network covers most business decisions. What matters is honesty about uncertainty: ranges, not false precision.

Why not run a survey or focus group?

Cost and reliability. Small samples in a small market produce confident-sounding noise. Observable behaviour and informed sources beat asking strangers hypothetical questions.
