I was wondering if you could answer a question I have about weights and psu/strata variables for analysing Understanding Society data.

If I want to analyse data from the BPHS, GPS, and EMB samples from Wave 2-5, which comes from both the self-completion questionnaire and the main survey, should I use:

e_indscus_lw: Longitudinal adult self-completion questionnaire weight
e_strata: Sampling strata
e_psu: Primary sampling unit

Many thanks for your time.

Kind regards

Yes, the variables are correct. Note, the BHPS sample will be excluded (as it is not in wave 1 of UKHLS). But you still will represent the UK population - so you should be fine.
Best, Olena

Great thanks. I'm not using data from W1 for that reason. I thought the BHPS would be included in the longitudinal weight from W5 because they were included from W2 onwards?

Kind regards

There is almost unlimited number of sets of weights we could provide. Yet providing w2+ longitudinal sc weights can be confusing for users. You can use w1 in your analysis as e_indscus_lw includes it. By dropping BHPS you loose a very small sample size, so your analysis results should not be affected.
Again your aim should not be to use a particular sample. Your aim should be to represent a population - and this can be perfectly achieved with e_indscus_lw weights.
Hope this helps, Olena
