Statistical Subdivision (SSD)
The Statistical Subdivision (SSD) is an Australian Standard Geographical Classification (ASGC) defined area which represents an intermediate level, general purpose, regional type geographic unit. SSDs consist of one or more Statistical Local Areas (SLAs) and cover, in aggregate, the whole of Australia without gaps or overlaps.
