Following is a response from DHS Senior Research Associate, Wenjuan Wang:
The simple answer is that we don't have separate sampling weights for each level, in this case, for the selection of facilities within a stratum and the selection of clients within a facility. There is a similar issue when people try to run multilevel models with DHS data. SPA has a client weight; but its computation takes the multi-stage selection into account, not just the selection of clients in the second stage. So it is not the ideal weight to use for the second level. In past work, we have used facility weight as the first level weight, and assumed equal weight for all clients in the same facility (which may not be true). In your case, you would let clwt=1. This is the best we can do and other researchers may have done it differently.
