Hi Austin, 

Thanks for this advice.  I'll give this a go...noting that is, as you say, equivalent to, but not exactly the same, as the hypothesis I need to test. 

Presumably the regression approach, where you have a single dummy for the sub-population, will be identical (or near identical) to:
- estimating svy: mean with over command (ie. mean for sub-population, and not in sub-population). 
- lincom after svy: mean. 

Or could the regression approach be applied, whereby you suppress the constant term?
Wouldn't this alternate regression approach be closer to what I'm after?  

Regards, 

Andrew
