Label

Usual residence address (Regional Council area), 2018 (iwi estimates) ^en-NZ

Description

Usual residence is the address of the dwelling where a person considers that they usually live. The 2018 Census provides the following guidelines for identifying usual residence:

• if you are a primary or secondary school student at boarding school, give your home address

• if you are a tertiary student, give the address where you live during term

• if you live in more than one dwelling, give the address of the one you most consider to be your home. If you spend equal amounts of time at different addresses, give only one of those addresses

• children in shared care should give the address where they spend most nights. If children spend equal amounts of time at different addresses, they should give only one of those addresses.

Other Variable Information

Quality information for usual residence address in the 2018 iwi affiliation estimated counts dataset

Quality rating: Moderate to poor quality

For many purposes, the 2018 iwi estimates provide a more relevant and up-to-date picture than continued use of 2013 Census iwi data. These iwi estimates are not official 2018 Census counts and the quality ranges from moderate to poor depending on how the data is used. It is difficult to understand changes occurring for an iwi over time for the population count as well as across characteristics due to differences between the 2018 and 2013 Censuses:

• Counts for the overall Māori descent population are substantially higher in 2018, reflecting improvements in the quality of Māori descent population counts in the 2018 Census as well as natural population change (births, deaths, migration). Māori descent – Information by Variable 2018 provides more information on the changes in the Māori descent population.

• Changes were made to the collection of iwi data in the 2018 Census, for example changes to the online form, and in 2017 there was a substantial review of the iwi classification with 32 iwi being added to the classification.

• There may also be a combination of real-world and methodological change at the characteristic level.

Producing estimates for the characteristics of an iwi is lower quality than we would expect from a census due to the high level of non-response. This is particularly the case when estimating the size of very small groups (e.g. <100).

The table below shows the contribution of data sources for the usual residence address variable released in the 2018 iwi affiliation estimates counts dataset.

Usual residence address – Information by Variable (2018 Census) provides a more detailed summary of the differences between the 2013 Census and 2018 Census questionnaires and the quality of the 2018 Census usual residence address data. However, the quality rating provided in the 2018 document does not apply to the usual residence address variable in the iwi estimated counts dataset.
