3. Sex (m for male, f for female)

Question 3 Sex

86. "Is this person male or female?"
Write M for males, F for females.

87. Usually the person's sex will be clear to you from the name and relationship but if you don't know, ask. Be particularly careful to get the correct sex of infants. Check that the sex you record is compatible with relationship - don't write M for persons shown as wives or daughters, nor F for persons shown as husbands or sons.
