  1. BMI = Body Mass Index
  2. SEIFA = Socio-economic indicators for areas. SEIFA is a series of indexes of socio-economic status devised by the Australian Bureau of Statistics using a range of indicators such as educational and employment status. The index used here is the Index of Relative Disadvantage, calculated at the postal area level. The national average is 1000 and the SD is 100. Higher values indicate more advantaged areas.
