Census - Severe housing deprivation estimate by ethnic group and region 2018 and 2023

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.

This data has been randomly rounded to protect confidentiality.
These figures are considered estimates because they are constructed from a combination of variables rather than being counted from a single direct question to individuals in the census.

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.

Figures in this data exclude Women’s refuge data, as well as estimates for children living in non-private dwellings.

The 2023 Census included an improved collection strategy among those who might be vulnerable to living in homelessness, including:

• those living in emergency and transitional housing
• those using temporary dwellings or a shelter that is not a private dwelling
• better matching of dwelling, household, and family structures with individuals
• roofless or rough sleepers.
  Despite these improvements, the estimates of those in severe housing deprivation are still likely to be undercounts.

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.

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.
