Following is a response from DHS staff member, Tom Pullum:
There are usually two reasons for subsampling.  The first is to reduce cost. All surveys start out with a finite budget and a long list of potential outcomes.  Most of the cost is for the fieldwork. Biomarkers, especially, add to the amount of time spent in each household. A second factor is respondent fatigue.  The more time that is spent in each household, the greater the burden on the respondents.  Subsampling is being used increasingly often in DHS surveys for both of these reasons.
