Following is a response from Senior DHS Stata Specialist, Tom Pullum:
Yes, in general admin 1 is region (v024) and the strata are v024 x v025 (urban/rural). There are only a few exceptions, especially in recent years, to this.
Yes, although admin 2 areas are nested in admin 1 areas, because of the role of v025 it is possible for admin 2 areas to straddle two strata.
You never have to adjust the weights or any part of the svyset command. As you may know, it is slightly better to use "svy, subpop(...):" than "svy:" together with "if...."
DHS data are representative for any subpopulations or areas in the sense that they are unbiased (when weighted). However, as you go to smaller areas, the number of clusters will fall off rapidly, and the standard errors of estimates will increase. In that sense, the quality of the estimates will deteriorate, but they are still unbiased.
