The Metropolitan Accessibility/Remoteness Index of Australia (Metro ARIA), developed by the Hugo Centre for Migration and Population Research (previously APMRC) and sponsored by the Australian Urban Research Infrastructure Network (AURIN), provides a nationally consistent and comparable dataset that quantifies geographic accessibility within the metropolitan area. SA1 Metro ARIA is for the year 2015. Spatial coverage is the 2011 ABS Urban Centre boundaries for each of the eight Australian Capital Cities.
