Hi,

In wave 10 there 145 respondents (j_indresp, count if j_ienddaty==2020 & j_ienddatm>=3) who completed their interview in March 2020 or later. So, you can use wave 9 or exclude these 145 cases. I will check with my colleague if doing the latter would require any changes to weights and get back to you.

Best wishes,
Piotr

When you don't weight our data your estimates will be biased in certain ways, please see the weighting section of the user guide for details: https://www.understandingsociety.ac.uk/documentation/mainstage/user-guides/main-survey-user-guide/why-use-weights
We always recommend to use an appropriate weight and take into account clustering (psu variable) and stratification (strata variable) of the sample, you can do that using svy suite in Stata. Due to the fieldwork design, excluding respondents from certain sample months might affect the sample representativeness, please see https://www.understandingsociety.ac.uk/documentation/mainstage/user-guides/main-survey-user-guide/how-to-use-weights-analysis-guidance-for-weights-psu-strata However, in this case, excluding these 145 case should have only a negligible effect, so you don't need to worry about this.

Best wishes,
