Digital boundaries

The 2016 Census digital boundaries facilitate the analysis and display of 2016 Census statistical data through their use in various software packages. Statistical data from other ABS collections, or from other sources, can be used in conjunction with these boundaries.

Australian Statistical Geography Standard (ASGS) boundaries have been constructed and maintained using the authoritative spatial data supplied by the
Public Sector Mapping Agencies (PSMA) Australia Ltd. The data quality and spatial accuracy of these boundaries are closely linked to the digital base map upon which they were based. When using these boundaries, users should be aware that, as a result of limitations of scale and accuracy of the original base map, they are not exact in area and extent. They therefore should not be used for highly detailed spatial analysis involving attributes that are highly dependent on area and extent factors.

The
PSMA national topographic datasets and 2016 Census boundaries are compatible with Geocentric Datum Australia (GDA94).

Dissemination of boundaries:
The ABS provides boundaries in Mapinfo interchange format (.mid .mif), ESRI Shape file format, MapInfo Tab file format and Geopackage.

Statistical data for use in conjunction with
the 2016 Census digital boundaries can be obtained from ABS Information Consultancy.

Use with alternative digital base maps:
The 2016 Census boundaries may be used in conjunction with base map data other than the recommended PSMA base map, however, alignment of boundaries to alternative base maps cannot be assumed.

The GDA94 datum used for both Census boundaries and the PSMA base map is compatible with the Global Positioning System (GPS). However, GPS satellite positions may be spatially less accurate than the boundaries in urban areas and more accurate than the boundaries in remote areas. Care should therefore be taken when combining features mapped by GPS with Census boundaries.
