'Years at usual residence' is the length of time up to the 2006 Census, expressed in completed elapsed years (including short-term absences, but excluding long-term absences), that a respondent has lived at their usual residence.
Relationship to questionnaire(s)
Data on years at usual residence comes from question 6 on the individual form (PDF 395kb).
The subject population is the people, families, households or dwellings to whom the variable applies.
The subject population for this variable is the census night population, as this question applies to all people in New Zealand on census night. Data on years at usual residence is also output for the census usually resident population.
The 2006 non-response rate for the usually resident population was 5.4 percent.
The 2001 non-response rate for the usually resident population was 4.4 percent.
Quality Management Strategy priority level
Years at usual residence 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.

There are no significant issues that users should be aware of.
Other things to be aware of
- There are some inconsistencies between years at usual residence when cross-tabulated with 'usual residence five years ago' and 'years since arrival in New Zealand'. The main cause of these inconsistencies is respondent error. There were also cases where rounding discrepancies led to a difference of one year between the response for the years at usual residence and the response for years since arrival variables.
- 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 allowed only one response to be selected for the years at usual residence question. If a further response was selected, the response given previously disappeared. Multiple responses to this question were possible when forms were completed on paper.
- On the Internet, there were two options available: 'less than 1 year', and 'greater than 1 year'. If the latter was selected, a text box was available for respondents to enter a numeric response. Decimal points could not be entered on the Internet form, but responses including decimals were possible when forms were completed on paper.
