Identifying relation to respondent of those being cared for
I've been looking at the x_aidhh variables in the Understanding Society individual response files. For individuals who indicated that they are caring for handicapped/disabled/elderly person in the household, I'm interested to find out who they are caring for (e.g. parent, grandparent, child and so on) and whether there is additional demographic information on the person being cared for in the data. Is there a way to do this?
I found that there are variables x_aidhuax, but these seem to only indicate whether the person number of those being cared for have been indicated. Is the person number available in another variable? I've also seen that there are x_aidhux variables, but I think that these provide the relationships of those being cared for who don't live in the household?
Thank you in advance.
