BHPS sample members without pids in Understanding Society
I am working on the attrition in BHPS and UKHLS.
I realised some cases in UKHLS (around 400 in each wave) comes from BHPS sample but do not have pids. I checked xwavedat (UKHLS) data to see if the pids are present there (so I would match pids using pidps from this file), but the same cases do not have pid in xwavedat either.
I thought everybody (even if they were under 16, or never interviewed) would have a pid.
Can you please explain, if I am doing something wrong? Is there any people in BHPS sample with missing pids in UKHLS waves?

All existing BHPS members in Understanding Society will have their original PID. But new entrants who join households of existing BHPS members don't have an existing PID as they are new. That is why you will find that their PID=-8.
