A type of CHARACTERISTIC.
A classification of the sex of a PERSON.
The classification is phenotypical rather than genotypical, i.e. it does not provide codes for medical or scientific purposes.
Note that ‘0 Not Known’ means that the sex of a PERSON has not been recorded. ‘9 Not Specified’ means indeterminate, i.e. unable to be classified as either male or female.
