For most analyses, wt_final and wt_final_online will be the required weights, the former (wt_final) for analyses of the full dataset (online and postal) and the latter (wt_final_online) for measures that are only collected online.
There are also two sets of time series weights (wt_time and wt_online_time) that need to be used for any analysis by month or quarter across the full survey year.
The former set (wt_time) is for the full sample (online and postal) and the latter (wt_online_time) is for the sample completing online only. The weights which are needed for different levels of analysis are outlined below.
