Hi,

I have a few questions regarding the routing of the variables lprnt, lnprnt, ladopt, lnadopt , and their derived variables.

1. The question universe suggests that this is asked once for everyone completing their first adult interview. However, I have noticed a high level of missingness (-8 inapplicable) in the first adult interviews for 16-year-olds — about 90% did not appear eligible for this question. I’m unsure why this is the case. Most of these 16-year-olds are rising16 , but not all. While the egoalt file can identify natural, step and adopted children within the household, it does not provide information on children living elsewhere. Could you clarify how this question was routed and what might explain the high level of missingness for 16-year-olds?

1. Would it also be possible to provide the routing for these questions in the BHPS? The question universe detailed on the website applies only to UKHLS. The questions are asked far less frequently in BHPS, and despite efforts to investigate the inapplicable cases, I have not been able to fully account for them.

1. Finally, I generated a variable that tracks parental status across waves using relationships in egoalt and the above parental status variables. I am aware that a cross-wave variable ( anychild_dv ) exists to identify natural parents, and it has significantly less missingness than mine — particularly for respondents coded as non-parents on anychild_dv . I would like to understand the source of the differences. Would it be possible to share the derivation code for this variable? Specifically, I am interested in how cases were handled where the initial parental status was "no children" (i.e., on lprnt ), no parent-child relationships were ever recorded in egoalt, and/or there were missing waves in between. Additionally, is there any further information available to help rule out the possibility that respondents may have had non-resident children in the interim (i.e., between observations)?

I appreciate your time and any insights you can provide.

Best regards,
Verena
