Question 3 - Sex
84. "Is this person male or female?" Write M for males and F for females.
85. Usually the person's sex will be clear to you from the name and relationship but if you don't know, ask. Never guess. Be particularly careful to get the sex of infants right. 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.
