Interviewer instructions
If the answer is 'None' for sons (or if she does not have any sons), record '0' in the space provided for sons. Similarly, if she has no daughters now living with her (or if she does not have any daughters), record '0' in the space for daughters. Remember, we are interested only in the respondent's OWN children - not foster children, children of her husband by another woman, or children of another relative.
