CDs are designed for use in census years for the collection and dissemination of Population Census data. In non-census years, CDs are undefined. In aggregate, CDs cover the whole of Australia (as defined in Chapter 1) without gaps or overlaps.
Special purpose CDs
Special purpose CDs are created so that special enumeration procedures can be applied. They include:
A number of these special purpose CDs have no actual boundary. They are represented as points instead of areas on maps. Indigenous Community CDs are defined where there is a significant Indigenous population.
Defence Establishments CDs are defined where there is a clear boundary and special enumeration procedures are required. Mining or Construction CDs are defined when the town or camp is expected to exist for at least two censuses.
Major Waterways CDs consist of water only and contain no population. They are mostly found in urban areas where an LGA boundary extends from the shore to include part of a body of water.
Nil CDs are created for areas where it is not expected that persons or dwellings will be enumerated. This may be an expanse of National Park which, if included in an adjoining populated area would provide a distorted view of population density for that area.
Off-shore, shipping and migratory CDs
Off-shore, shipping and migratory CDs are not spatial units in the usual sense - they have no defined boundaries. They are designed to facilitate the recording of people on census night who are off-shore on oil rigs, drilling platforms and other structures; on board vessels in and between Australian ports; or are in transit on board long distance trains, buses and aircraft.
Off-shore, shipping and migratory CDs are not defined for the Australian Capital Territory and the Other Territories. For the 2001 Census, Australian residents temporarily in Antarctica, Heard or Macquarie Islands, were included in the off-shore, shipping and migratory CDs of Tasmania.
CDs are identified by unique six-digit codes within each S/T.
1160501 is CD 160501 of New South Wales
5051901 is CD 051901 of Western Australia
