Understanding Society User Support

Hi,

I am contacting you as I have a question regarding the use of weights. I would like to provide representativeness on key demographic variables for a sample that we recruited online this year as part of a large-scale experiment. I am currently using the last wave of Understanding Society (2022) to do so, and use mainly individual information. Given that our recruited sample is restricted to (i) 18+, (ii) parents of at least one child, (iii) residing in England, I applied the same conditions to the last wave of Understanding Society for comparison purposes.
So far, I have produced the descriptive statistics for key demographic variables (i.e., share born in the UK, main groups of ethnicity, has a University degree, etc.) without any weighting.
Yet, I am wondering if, to compare my sample with that from Understanding Society, I need to apply any particular cross-sectional weighting?
Given I condition our sample, I am not sure at all about the best weighting procedure to adopt.
I would greatly appreciate if you could provide me with any assistance with respect to this.
Thank you very much in advance.
Best,

Césarine Boinet
