How this variable is created
The types of Non-private dwelling is sourced from the ABS Address Register. For information on how the Address Register is maintained, refer to ABS Address Register, Users' Guide.
It is reviewed by Census enumeration management staff prior to Census night and verified by Census Field Officers after calls or visits to the establishments. Non-private dwellings can also be created or have their details modified throughout this time.
History and changes
Information on the types of Non-private dwellings that people are located in on Census night has been collected in every Census since 1911.
Since the 2006 Census, additional response options were introduced to identify immigration detention centres, youth or backpacker hostels and ski lodges.
Since 2016, NPD type is sourced from the ABS Address Register and is updated as needed from information collected by ABS field officers during enumeration.
The output categories for this classification were unchanged for 2021.
Data use considerations
Hotels (01) and private hotels (04) are categorised differently within Type of non-private dwelling (NPDD). This is mainly because of differences in length of residency, service provision, and how the hotel or private hotel classifies itself.
The category '12 - Accommodation for the retired or aged (not self-contained)' is accommodation where meals are provided.
Self-contained retirement villages where the residents live independently are not classified as Non-private dwellings. These are Occupied private dwellings and can be identified by the variable Dwelling location (DLOD).
