We compared study participant demographic variables with census results from the Campbelltown area (ABS, 2011) to assess participant representativeness. About 58% of participants were female (ABS census = 52%)with a median age of 41 (ABS census = 42) and a range of 15–79 years. About 43% of participants were in families with children (ABS census = 45%). Thus, the study participants were close to representative of the general Campbelltown population on these three demographic variables.
