Classifications and Related Standards System (CARS)

The Classifications and Related Standards System (CARS) is a computer system for the storage of all economic, social and geographic classifications data used in Statistics New Zealand. The data stored includes standard classifications, historical classifications required for the analysis of historical data, and survey specific classifications which are not standard.

Crowding in households

Crowding in households relates to situations where the number of people residing in a household exceeds the capacity of the household to provide adequate shelter and services to its members.

Dwelling

A dwelling is any building or structure, or part thereof, that is used (or intended to be used) for the purpose of human habitation. It can be of a permanent, temporary or even mobile nature and includes structures such as motels, hotels, hospitals, prisons, motor homes, huts, and tents.

At the highest level, dwellings are classified as private or non-private. A private dwelling accommodates a person or a group of persons, but is not available to the public. Included are: houses, flats, and apartments; residences attached to a business or institution; baches, cribs and huts; garages; caravans, cabins and tents; vehicles; vessels; or dwellings of the above types that are under construction.

All other dwellings are non-private and are available to the public. They may be available for use generally, or by virtue of occupation or study, special need, or legal requirement. Such dwellings may have facilities (such as a dining room) that are for shared use. These dwellings include: hotels and motels; guest houses and boarding houses; hostels; public and private hospitals; homes for the elderly; educational, welfare, religious and charitable institutions; prisons and penal institutions; defence establishments; work camps, staff quarters and seasonal quarters; motor camps; and other communal dwellings. If this type of accommodation includes units that are designed for the exclusive use (temporarily) of one or more persons, the units are considered to be part of the non-private dwelling and not separate non-private dwellings. Private residences that are attached to non-private dwellings are, however, considered to be separate private dwellings.

Dwelling occupancy status

Dwelling status refers to one of the categories of dwellings as selected by the enumerator or interviewer. These categories are based on whether the dwelling is occupied or not and why it is unoccupied.

Dwelling type

Dwelling type refers to one of the categories of dwellings as selected by the responding unit. These categories are based on the structure and function of the dwelling and include private and non-private dwellings.

Furnished bedroom

A room furnished as a bedroom should include a sleeping facility such as a bed, mattress or mat, and could include items such as a dresser, and/or wardrobe, and/or chest of drawers.Non-private dwelling

Non-private dwellings are available to the public. They may be available for use generally, or by virtue of occupation or study, special need, or legal requirement. Such dwellings may have facilities (such as a dining room) that are for shared use. These dwellings include: hotels and motels; guest houses and boarding houses; hostels; public and private hospitals; homes for the elderly; educational, welfare, religious and charitable institutions; prisons and penal institutions; defence establishments; work camps, staff quarters and seasonal quarters; motor camps; and other communal dwellings. If this type of accommodation includes units that are designed for the exclusive use (temporarily) of one or more persons, the units are considered to be part of the non-private dwelling and not separate non-private dwellings. Private residences that are attached to non-private dwellings are, however, considered to be separate private dwellings.

Private dwelling

A private dwelling accommodates a person or a group of persons, but is not available to the public. Included are: houses, flats, and apartments; residences attached to a business or institution; baches, cribs and huts; garages; caravans, cabins and tents; vehicles; vessels; or dwellings of the above types that are under construction.

Private residences that are attached to non-private dwellings are, however, considered to be separate private dwellings.

Where the are shared cooking facilities, occupants should generally be regarded as flatmates, boarders or lodgers in common; and only one dwelling from should be completed.

Single room apartment: A single-room apartment that is not self-contained at least in respect of sleeping or cooking facilities is not regarded as a separate dwelling.

Note: A private dwelling with more than 5 boarders or lodgers should be classified as a boarding house (a non-private dwelling).

Service area

A service area may be:

  • equipped with appliances for washing, ironing and other domestic work
  • used for storage
  • used as a thoroughfare
  • used mainly for purposes other than ‘habitation’ (ie a room which is not considered to provide actual ‘living space’)

Service rooms and areas include: pantries, hallways, garages, spa-rooms, walk-in wardrobes, corridors, verandahs, laundry rooms, boiler rooms, toilets and bathrooms.

Residual categories

Don’t know

Use of this category is discretionary. The use of a category capturing don't know responses is most applicable to household surveys where don't know may be a legitimate response to certain questions.

Refused to answer

This category is only used when it is known that the respondent has purposefully chosen not to respond to the question. Use of this residual category in processing is optional. Its use is most applicable in face-to-face or telephone interviews, but may be used in self-completed questionnaires if the respondent has clearly indicated they refuse or object to answering the question.

Response unidentifiable

This category is used when there is a response given, but:

  1. the response is illegible, or
  2. it is unclear what the meaning or intent of the response is - this most commonly occurs when the response being classified contains insufficient detail, is ambiguous or is vague, or
  3. the response is contradictory eg, both the yes and no tick boxes have been ticked, or
  4. the response is clear and seemingly within the scope of the classification but can not be coded because no suitable option (particularly other residual category options such as “not elsewhere classified” or “not further defined”) exists in the classification or codefile.
Response outside scope

This category is used for responses that are positively identified (ie the meaning and the intent are clear) but which clearly fall outside the scope of the classification/topic as defined in the standard.

Not stated

This category is only used where a respondent has not given any response to the question asked, ie it is solely for non-response.
