Description

Dear Understanding Society team,

I am pleased to work with your newly released family matrix. My question regards the parent-child relationship identifier.

For my research I am interested in the first (alive) child of a parent. I aim to identify the oldest child by checking which of the listed children is the oldest, but I am wondering whether actually all of a parent's children are listed. If the oldest child of a parent for example has rejected to ever participate in the survey whereas younger siblings have participated, then my identification gives incorrect results.
Would you be able to clarify whether this is a possibility, and if so, how often you expect this case to occur?

Moreover, I wonder how you would recommend me to deal with twins. Specifically, in the household files where children are often already listed in order of birth, do you use a general rule to decide which twin to put first and which second (e.g., based on whether the child is a boy or girl)?

Thank you very much in advance!

Best,
Lieke

Here is the response from the data team: The Family Matrix contains people reported in INDALL (those enumerated in the household grid) and the relationships listed in EGOALT (the relationships between the people in the household). Therefore, only children enumerated in the study will be listed (including those who may not have provided an individual interview), this may exclude children that do not live with the respondent or children not enumerated into the survey for any other reason. Children are not always listed in INDALL/EGOALT by order of birth, so it’s best to merge a DOB variable (e.g. doby_dv [and dobm_dv if you have access to special licence]) to find out who’s the eldest. There is also no general rule for the specific order for twins either. 

Best wishes,

Dear data team,

Thank you very much for the clarification, this is very helpful.

I would like to ask one more follow-up question. Is the procedure that you describe streamlined for both BHPS and US respondents and waves, i.e., does the family matrix also include the relationships identified on the basis of older indall and egoalt files from BHPS waves?

Looking forward to hearing from you,

Best wishes,

Lieke
