PRINCIPLES OF THE ASGS
The Australian Statistical Geography Standard (ASGS) is constructed on the principle that it must fulfil user needs for geospatially enabled statistics, while also conforming to general classification principles.
The ASGS is designed to meet user needs for social, demographic and economic statistics. The regions of the ASGS below the State or Territory level are designed such that they are:
- useful and relevant for data dissemination
- flexible for aggregation into larger units
- useful building blocks for user-defined regions.
The ASGS is constructed on the basic classification principles that:
- members within one class are of the same type
- classes are uniquely defined so as to be mutually exclusive
- in total, the members in each class cover the entire class.
As a result, the regions of each hierarchical structure of the ASGS are:
- of the same type, delimited by well-defined criteria
- clearly defined by precise boundaries
- uniquely identified by codes and names
- mutually exclusive
- in aggregate, cover the whole area to which that hierarchy applies.
