The top three types, 5, 8 and 2, account for just under half of all results, which is a heavier concentration at the top than the framework’s own literature tends to assume.
Type 9 sitting mid-table at 13.0% is worth noting against the common claim that Nines are under-detected by self-report. A type defined partly by deferring and not asserting is exactly the type a questionnaire might miss, and this sample does not show that happening.
Method
- Every completed Enneagram assessment that produced a primary type, counted once per completion.
- Wing is recorded separately and is not counted here.
- Staff, demo and test accounts are excluded.
What this cannot tell you
- Self-selected sample. These are people who chose to take an Enneagram assessment, not a population.
- The Enneagram is a motivational framework and self-report struggles with motivation in a way it does not with behaviour. People report what they believe drives them.
- Type 9 is thought to be under-detected by self-report questionnaires, because the type is characterised partly by not asserting a position. If that is right, the 13.0% here understates the type rather than overstating it. (This limit named 2.3% until 2026-10-06, a figure from the smaller wing sample that was never on this page; the corpus this study publishes has Nines mid-table.)
- This is Crystal’s implementation. Other Enneagram instruments would produce different shares.
