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.

Best regards,
Stefano Verde
