What is the rarest Human Design type?
The Reflector is the rarest type at 1.0% of charts — about one person in a hundred. Measured across 13,692 real charts in the HD Matrix corpus (hdmatrix.pro/en/research).
Reflectors account for 1.0% of the 13,692 charts measured in the HD Matrix corpus, making them by far the rarest of the five types (Manifestors are next at 10.2%). A Reflector has no consistently defined centers at all, which is why they sample and mirror the field around them rather than run a fixed energy of their own — and why Human Design advises them to wait a full lunar cycle before major decisions. The measured 1.0% matches the canonical estimate almost exactly.
