Column (2) Mother's status
Here we want to know where the birth mother resides or if she has died.
Does the birth mother live in the household, that is, the birth mother and her children reside together in the same household?
Does the birth mother reside outside the household in which her children reside?

Method of filling in the form:
The way to ask the question is as follows:

"Is this person's (asked for each household member) mother living in this household, in another household, or has she died?"

Enter a code depending on the answer of the respondent.
If the birth mother does not reside in this household and it is unknown whether or not she has died, circle code 4 (don't know).
If the birth mother resides in this household, enter code 1 in column 2, and then ask:
"Who among the people in this list is this person's mother?"
