Second address/ residence
Sophie Davies
Public
Seen by 198
Many people in New Zealand move between different addresses or have more than one residence. Examples of this are:
- children whose week is split between separate parental homes,
- students whose term-time address differs from their home address and
- people whose working week address differs from their home address.
The information requirements identified are a need to understand:
- regional population fluctuations,
- family connections across households,
- New Zealand’s housing stock, and
- second home ownership rates.
In addition, this information could provide operational gains for Statistics NZ and help to ensure the quality of the population count in the census.
The Office for National Statistics (ONS) in England and Wales collected information on second address and the purpose of that address in their 2011 Census. They used a definition of 30 days or more a year to identify second addresses. The Australian Bureau of Statistics (ABS) is also currently considering including it in their 2016 Census.
It may not be possible for the census to meet all information needs identified in this topic area, because the amount of information we can collect on any one topic is limited. We also need to be think about respondent burden when considering adding another address question in the 2018 Census.
Our current recommendations relating to second address/ residence
We recommend that second address or residence be considered for inclusion in the 2018 Census.
We invite feedback on information requirements relating to second addresses or residences, and which types of information would be of the greatest value and highest priority to collect.
See our preliminary view of 2018 Census content (pages 21-22) for a more detailed discussion on second address/ residence information.

I have already researched unoccupied dwellings from 2013 and made some maps of them. See my website for a presentation that looked at the distribution. http://www.ollivier.co.nz/download/census/index.shtm
My conclusion is that the majority of the 10.6% are indeed in coastal communities at the beach, but where it is hard to let them out due to a lack of local jobs. Note that the counts are not available at the meshblock level.

Related to the second dwelling is the fact that all dwelling statistics are based on 'occupied dwellings' or 90% of homes. Should every series have a count for 'not measured' so that the total counts include the unoccupied dwellings? Otherwise there is a significant uncertainty that has not been quantified.
It is not evenly spread. Some communities have 50-80% unoccupied dwellings so the counts for those areas need to be discounted.

It is important to look up the definition of a 'dwelling'. It matches the valuation roll definition of a 'unit' . Correspondents may be surprised to see that each motel unit is a 'unit' because it has bedroom, bathroom, kitchen. This makes some areas with lots of accommodation look empty in March when the census is held.

Since the second address will not be visited by the census collector, how will the address be validated? I fear a lot of indecipherable addresses and false positives. Second homes will often not have a delivery address so will be missing from NZ Post. Even the council does not give these places an address, only a rating and legal description.

Kim, welcome to the discussion on second residence and for sharing your findings on dwellings.
At the moment, we are still looking at how the second residence/address question(s) will be structured and it depends on inputs like what you have mentioned. This is important for us to be aware of user needs such that the questions can be correctly framed to meet that need.
Thank you.

I'm writing from point of view of and IDI (Integrated Data Infrastructure) data analyst and assuming that 2018 Census data will be linked to IDI. For IDI data analysis, the extra address information (both the second residence and 12 months previous) will help fill major gaps in the patchwork of address information in the IDI currently. Having second residence will help avoid misleading 'non-matches' if Census and admin data are compared only on the basis of the first address given in the Census.

Welcome to the discussion Charles, and thank you for sharing.
IDI is treated separately from Census. Any linking of the two sources must undergo a privacy impact statement and should be cleared with the Privacy Commissioner and the Government Statistician. SNZ does not link Census and IDI.
For anonymized addresses in IDI to be relevant and updated, it must be addressed from the administrative data source, for instance IRD or MSD.

Hi Cecile
As an IDI user I'm aware that the Census isn't currently linked to the IDI. But I understood that a decision on whether to link the 2013 Census was pending
(i.e. aiming to have the kind of clearances you mention confirmed or denied over the next couple of months).

Addresses in IDI are really such a challenge. We can do more if addresses are updated - especially those collected by IRD.
Thank you Charles for your interest.

Ellen, welcome to the discussion on second residence/address.
Thank you for your input. Your suggestion will give us further clarity on the usefulness of data generated. How the question will be framed depends on user needs. What you have suggested will guide us on what variables are required to meet that need.
Again, thank you.
