  1. All figures within the table are ‘000s.
  2. ^1: These values represent the size (‘000s) of the population with these access scores. Row totals correspond to the total Victorian population residing in the 5 population size groups.
  3. ^2: These values represent the net population change (‘000s) within each population size group to the corresponding access scores following the addition of each distance-decay function. Negative values indicate a net drop in the number of residents with access scores in that category. All row totals equal 0.
