The 2001 non-response rate was 4.2 percent.
Quality Management Strategy priority level
Fuel type used to heat dwelling is a supplementary variable.
The Census Quality Management Strategy assigns a priority level to all census variables.
Supplementary variables do not fit directly in with the main purpose of a census, but are still of importance to certain groups. These variables have third priority in terms of effort and resources.
All data must meet minimum quality standards in order to make it suitable for use.

Other things to be aware of
- Liquified petroleum gas (LPG) is available as mains gas in some parts of the South Island.
- All census data was subject to considerable checks (including edits) during processing and evaluation, to ensure that it meets quality standards and is suitable for use. These checks were applied to data supplied both on paper and on Internet forms. In addition to these quality checks, the Internet form had built-in editing functionality that directed respondents to the appropriate questions and ensured that their responses were valid. As a result of this, data from Internet forms may be of higher overall quality than data from paper forms. The significance of this will depend on the particular type of analysis being done.
- There were differences between how the forms were completed on the Internet and on paper for this variable:
- The Internet form did not allow the inconsistent multiple response of 'don't ever use any form of heating in this dwelling' and the selection of one or more fuel type categories. If the 'don't ever use any form of heating in this dwelling' box was marked, any other response options to fuel type disappeared. Inconsistent multiple responses to this question were possible when forms were completed on paper.
- On the Internet, it was only possible to give text responses if 'other fuel(s)' was marked. When forms were completed on paper, it was possible to give a text response but not mark the 'other fuel(s)' tick box.
