Why am I seeing this?
This data is from the Census. The past two censuses had relatively low response rates, particularly for some areas of New Zealand and groups of people.
Where information was missing or unreadable, Stats NZ attempted to use data from a range of places such as previous censuses 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
This data is not comparable with the results of the 2013 Census, because the 2013 Census only included people aged 15 years and over.
Please note the following known issues with the data:
- Study participation data for children should be used with caution because there is an undercount compared with expected figures, especially for early childhood (1 to 4 years). This may be due to parents considering early childhood education as childcare rather than education.
- Census does not distinguish between formal and informal study. An individual may consider themselves as ‘studying’ without a formal enrolment.
- Census study participation respondents aged 18 and over may include those undergoing on-the job industry training as well as those enrolled with industry training organisations.
- Census respondents enrolled in an educational institution but who were not actively studying at the time of the census may have indicated that they were not participating in study at the time of the survey, while they would be included in admin data.
This variable measures the number of people attending, studying, or enrolled in tertiary institutions, school, early childhood education, or any other place of education or training. It is grouped into full-time study (20 hours or more a week), part-time study (less than 20 hours a week), and those not studying.
This information applies the entire census usually resident population.
Response rates and final data sources
The response rate from 2023 Census forms was 84.4%. 13.8% of responses were sourced from administrative data supplied by the Ministry of Education. The remaining 1.8% of responses were imputed.
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.
Geographically the census includes the North Island, South Island, Stewart Island, and the Chatham Islands, plus largely uninhabited islands including the Kermadec Islands, Three Kings Islands, Mayor Island, Motiti Island, White Island, Moutohora Island, Bounty Islands, Snares Islands, Antipodes Islands, Auckland Islands, and Campbell Island.
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 2023 Census, held on Tuesday 7 March, was the 35th 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 with making 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.
