May be this:

RangeSum(

Count({<[Population Group Code] = {2}, [Date] = {">$(varMinSelectedDate)<=$(varSelectedDate)"}, [MonthYear] =, [Year] = , [BGMonth] =>} DISTINCT [Person ID])

Avg({1}0))

Have you tried replacing the variables in the set analysis with the actual dates hard coded just to see if that makes a difference?
