The Enneagram is a personality typing system that consists of nine different types. Everyone is considered to be one single type, although one can have traits belonging to other ones. While it's uncertain whether this type is genetically determined, many believe it is already in place at birth.
The nine types (or "enneatypes", "ennea" means "nine") are universally identified by the numbers 1 to 9. These numbers have a standard way of being placed around the Enneagram symbol.
People of a particular type have several characteristics in common, but they can be quite different nevertheless. It depends among other things on their level of mental health. Unhealthy (neurotic) people from a particular type can look quite different from healthy ones.
