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.
