Data Quality

Using this data

Use this data with caution. This data was rated moderate quality by Stats NZ. Read the warnings and response rate metadata below before using.

Stats NZ gives data an overall rating based on sources and coverage, consistency, and data quality.

Why am I seeing this?

This data is from the 2018 Census. The 2018 Census had low response rates, particularly for some areas of New Zealand and groups of people. Read more about this on Stats NZ's website.

Where information was missing or unreadable, Stats NZ attempted to use data from a range of places such as the 2013 census or administrative data that is collected by other government agencies. If that isn't available, Stats NZ use statistical models to predict what the missing data would have been. This is called imputation.

Things to be aware of

The high non-response rate for 2018 means that this data may not always fully reflect real-world heating use or trends. This data does not indicate how many heating appliances of each type were used in a home eg the number of heat pumps used, or whether one electric heater or multiple electric heaters were used. Each type of heating reported was recorded once only. This question was first introduced in the 2018 Census. No comparisons with previous censuses are available.

About this data

Subject matter

This information refers to the types of heating that are usually used in homes. It indicates the appliances used, and, in most cases, the fuels used (eg heat pump, fixed gas heater, wood burner). Any types of heating that are only used very rarely or are available but not used are excluded. Insulation is not a heating type.

Response rates and final data sources

Main type of heating: The response rate from 2018 Census forms was 92.3%. There was no information for 7.7% of homes. No alternative data source or imputation was used to replace missing responses.

Definitions

Census usually resident population count of New Zealand: a count of all people who usually live in and were present in New Zealand on census night. It excludes overseas visitors and New Zealand residents who are temporarily overseas.
Census night population count of New Zealand: a count of all people present in New Zealand on census night. This includes visitors from overseas who are counted on census night but excludes residents who are temporarily overseas on census night.
Dwelling: A dwelling is any building or structure that is used, or intended to be used, for human habitation. There can be more than one dwelling within a building. For example, each apartment in an apartment building is a dwelling.
Household: either one person who usually resides alone, or two or more people who usually reside together and share facilities in a private dwelling. Included are people who were absent on census night but usually live in a particular dwelling and are members of that household, as long as they were reported as being absent on the dwelling form or the household set-up form.
Response 'stated': Members of the subject population (eg. people or dwelling) for which the data was obtained through a census form, administrative sources, or imputed.

Data calculation/treatment

This data has been randomly rounded to protect confidentiality.
Figure.NZ calculated percentages based on the 'Total stated' values for each variable. Individual percentages may not sum to 100% and values for the same data may vary in different tables.

Changes to data collection/processing

The 2018 Census was a modernised census based on models used in 2016 by the Canadian and Australian statistical agencies and then applied in the New Zealand context. Stats NZ collaborated with census experts from both countries when designing the model.

Under the new model, how Stats NZ enabled/collected from the respondents changed from predominately field-based activities to 80 percent mail-out with a reduced field presence and increased communications, marketing and engagement. The way respondents completed their forms also changed, with a greater focus on online completion over paper. The majority of the population was encouraged to complete the census online using an internet access code mailed to their households before census night. The new collection model therefore relied on the public to self-respond, rather than wait for a visit from field staff. Field follow-up activities were also planned.

The main areas of change were:
- phasing the model (prepare, enable, remind and visit)
- strategies used across the different phases
- mailing out “call to action” letters with an internet access code and instructions on how to order paper forms, if required, as the first interaction with census
- reducing the number of field staff, with a new structure and roles
- outsourcing the recruitment functions for field staff
- introducing new field technology
- creating a new address frame (a list of all dwellings in New Zealand)
- an integrated communications campaign including community engagement
- a new approach to processing the census data.

About this dataset

The New Zealand Census of Population and Dwellings is the official count of how many people and dwellings there are in New Zealand. It provides a snapshot of our society at a point in time and helps to tell the story of its social and economic change. The 2018 Census, held on Tuesday 6 March, was the 34th New Zealand Census of Population and Dwellings. The first official census was run in 1851, and since 1877 there has been a census every five years, with only four exceptions.

Purpose of collection

Census information is used by government agencies, local authorities, businesses, community organisations, and the public for developing and implementing new policies, research, planning, and decision-making. It helps us make decisions about how to best use public funding, especially in areas of health, education, housing, and transport.
The census is also the primary source of information used for deciding the number of general and Māori electorates, along with data from the corresponding Māori Electoral Option.
