Extrapolation vs Enumeration: How Do You Read a Market Report?

The Thailand Cannabis Report  ·  2026 Edition  ·  Field-verified market intelligence  ยท  Last reviewed: 2026

Every market estimate is built one of two ways. It is either extrapolated or enumerated, and knowing which you are holding tells you almost everything about how far to trust it.

Extrapolation

Extrapolation takes what happened last period and projects it forward with a growth assumption. It is fast, it is cheap, and it scales beautifully across markets. Its weakness is simple: it assumes the recent past is a reliable guide to the near future. When a market is turning, that assumption quietly breaks, and the estimate inherits the error.

Enumeration

Enumeration counts. It is slow, it does not scale, and it means being physically present in the market. We walked more than 850 dispensaries, sat with farm operators and shop owners, and bought as customers across the country. You cannot template that, which is exactly why it captures what the templates miss.

When you next read a Thailand cannabis figure, ask one question of it: did someone build this from the ground, or from a curve? If the method is not stated, you are almost always holding an extrapolation. In a market like this one, that matters.

Quick answers
What is the difference between extrapolation and enumeration in market sizing?

Extrapolation projects last period's trend forward with a growth assumption. Enumeration counts, which is slow and does not scale but means being physically present in the market.

Why does extrapolation fail in a turning market?

It assumes the recent past is a reliable guide to the near future, and when a market is turning, that assumption quietly breaks and the estimate inherits the error.

How was this report's market figure built?

By enumeration: walking more than 850 dispensaries, sitting with farm operators and shop owners, and buying as customers across the country.

How can you tell if a published figure is an extrapolation?

Ask whether it was built from the ground or from a curve. If the method is not stated, it is almost always an extrapolation.
