Interviewer instructions
9. Sex
Write "M" for males and "F" for females in the space provided.
It is important to ask for the sex of the person when information is being given to you by a third person. Do not infer the sex from the name or names to the person. Bear in mind that some names can be misleading in this respect. For example, some people use George as a short form for Georgina and Ben for Bernice.
