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!
