'Census night address' is the meshblock of the dwelling where a respondent is located on census night. For passengers on overnight trains and buses, the destination of the passenger is deemed to be the census night address.
A meshblock is the smallest geographic unit for which statistical data is collected by Statistics New Zealand. Meshblocks vary in size from part of a city block to large areas of rural land. Each meshblock abuts another to cover all of New Zealand, extending out to the 200-mile economic zone (approximately 320 kilometres). Meshblocks aggregate to build larger geographic areas, such as area units, territorial authorities, and regional councils.
Relationship to questionnaire
Data on census night address comes from question 8 on the individual form (PDF 395kb). However, if a respondent marked 'at the address I gave in question 5' (ie on census night, 7 March 2006, they were at the address where they usually live) for question 8, question 5 was also used.
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, which includes the use of substitute individual forms. Substitute individual forms are individual forms created by Statistics New Zealand where there is sufficient evidence that a person exists but Statistics NZ has no corresponding individual form. Substitute forms are only created for the census usually resident population.
Census night address does not have a non-response rate, as all forms received have a meshblock code. When the respondent did not answer the question, the census night address is taken to be the meshblock code filled in by the collector. This includes situations in which an entire individual form for a person within a household was not answered, and situations in which an entire household did not respond.
Quality Management Strategy priority level
Census night address is a foremost variable.
The Census Quality Management Strategy assigns a priority level to all census variables.
Foremost variables are core census variables that have the highest priority in terms of quality, time and resources across all phases of the 2006 Census.
All data must meet minimum quality standards in order to make it suitable for use.
Comparability with 1996 and 2001 Census data
There are no issues affecting the comparability of this data with 1996 and 2001 Census data.
There are no significant issues that users should be aware of.
Other things to be aware of
- 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:
- On the Internet, the census night address question had to be completed in order for the respondent to submit the form. Non-response to this question was possible when forms were filled in on paper.
