Description

Hi, we are trying to derive a longitudinal weight for linked youth datasets, following guidance given by Peter Lynn previously. Please could you explain why the youth self-completion weight is 0 for more than 1/5 of the youth s-c respondents at wave 2?
thanks

Dear Jane - many thanks for your query and for bearing with us over the Christmas holiday period. I have passed on your query to our weighting team.

Best wishes, Victoria.

Jane,

It looks to me that the weight is present for 95% of respondents. Specifically, b_ythscus_xw is missing for only 0.7% of GPS+EMB cases, and b_ythscbh_xw is zero for 18.9% of BHPS cases:

|         samp
wght | us bhps | Total
-------------+----------------------+----------
b_ythscus_xw | 3,876 0 | 3,876 | 99.31 0.00 | 77.21
-------------+----------------------+----------
b_ythscbh_xw | 0 906 | 906 | 0.00 81.11 | 18.05
-------------+----------------------+----------
both zero | 27 211 | 238 | 0.69 18.89 | 4.74
-------------+----------------------+----------
Total | 3,903 1,117 | 5,020 | 100.00 100.00 | 100.00

The higher rate of zero weights for the BHPS sample is because the weight relies on having a valid longitudinal weight for at least one adult in the household, and BHPS has had a lot of waves by that point!
