TCM Constitution Statistics: What 20,759 Assessments Reveal

Medically reviewed by Jimmy Yu, Certified Acupuncturist · Framework: Wang Qi / China Association of Chinese Medicine (CACM) nine-constitution model

In 20,759 completed assessments from 163 countries, Qi Stagnation is the most common primary constitution at 26.5% — first in every age group. Only 6% of people assess as Balanced, and in 43% of results the top two biased patterns sit within five points of each other, so mixed constitutions are the norm, not the exception.

Share of assessments where this pattern is the primary result.

By gender

Among 15,232 women: Qi Stagnation 26% · Inherited Special 18% · Qi Deficiency 17%.
Among 5,391 men: Qi Stagnation 28% · Qi Deficiency 15% · Phlegm-Dampness 11%.

The headline pattern is shared — Qi Stagnation leads for both — but the second row differs: women skew toward Inherited Special, men toward Qi Deficiency.

By age group

18–29n=845Qi Stagnation 35% · Qi Deficiency 16%
30–39n=2,012Qi Stagnation 37% · Qi Deficiency 16%
40–49n=2,611Qi Stagnation 30% · Qi Deficiency 15%
50–59n=5,721Qi Stagnation 26% · Qi Deficiency 17%
60+n=9,392Qi Stagnation 23% · Inherited Special 19%

Qi Stagnation peaks in the 30–39 band — the working-and-caring-for-everyone years — and eases with age, while patterns of depletion and sensitivity take up more of the picture after 60.

Method, honestly stated

Figures are aggregates of the 29-question IdentifyTCM assessment (Wang Qi / CACM nine-constitution framework), taken online by a self-selected audience — largely viewers of two TCM YouTube channels with 145,000+ combined subscribers. This is not a population-representative survey; it describes people interested enough in their health to take a three-minute assessment. Counts update daily as new assessments come in. Nothing on this page diagnoses, treats, or prevents any disease.

Frequently asked questions

What is the most common TCM constitution?

In IdentifyTCM's data of 20,759 assessments, Qi Stagnation (qiyu) is the most common primary constitution at 26.5%, and it ranks first in every age group from 18 to 60+.

How rare is a Balanced constitution?

Only 6% of assessments identify Balanced (pinghe) as the primary result — fewer than 1 in 20. Most people show at least one biased pattern worth working with.

Do most people have exactly one constitution?

No. In 43% of assessments the top two biased patterns score within 5 points of each other, so mixed constitutions are common — which is why guidance usually centres on the primary pattern while respecting the secondary one.
