Notes Index based on road distance measurements from 11,879 populated localities to the nearest service centres in five size categories based on population size. The five distance measurements, one to each level of service centre, are recorded for each populated locality and standardized to a ratio by dividing by the Australian mean for that category. Ratios are summed to produce the ARIA score for each populated locality across Australia and interpolated to a 1km resolution grid. The grid provided in this toolkit is re-sampled to 5km resolution: ARIA values are available from GISCA for all standard ABS geography (ASGC).
