Dear Bryan and Steven, thank you very much for your help. Only today the national statistics office confirmed to me that: 1) no clusters were used in the household survey I have, and 2) they cannot release information about strata. Thus, my microdata set only includes sampling weights (which sum up to Ireland's household population, N). Given this, what is the best I can do? I have thought of the following: svyset _n [pw = my_sampling_weights] bsweights bsw, n(0) reps(100) bs4rw exp_list, rw(bsw*): command [pw = my_sampling_weights] The first line - on Steven's suggestion - states that there is a single stratum only and each household is a PSU. The second line creates bootstrap resampling weights, which are then used in the bootstrap of exp_list (-bsweights- and -bs4rw- are commands written by Stas Kolenikov). I'm aware that not having information on strata affects results. However, my two questions are: 1) Do sampling weights mitigate this error? 2) Are the three command lines above the best I can do, given the information limitations? Once again I'd greatly appreciate your help.
