Subnational census usually resident population

The census usually resident population count of an area (subnational count) is a count of all people who usually live in that area and were present in New Zealand on census night. It excludes visitors from overseas, visitors from elsewhere in New Zealand, and residents temporarily overseas on census night. For example, a person who usually lives in Christchurch city and is visiting Wellington city on census night will be included in the census usually resident population count of Christchurch city.

​

Population counts

Stats NZ publishes a number of different population counts, each using a different definition and methodology. Population statistics – user guide has more information about different counts.

​

Caution using time series

Time series data should be interpreted with care due to changes in census methodology and differences in response rates between censuses. The 2023 and 2018 Censuses used a combined census methodology (using census responses and administrative data), while the 2013 Census used a full-field enumeration methodology (with no use of administrative data).

Disability indicator

This data should not be used as an official measure of disability prevalence. Disability prevalence estimates are only available from the 2023 Household Disability Survey. Household Disability Survey 2023: Final content has more information about the survey.

Activity limitations are measured using the Washington Group Short Set (WGSS). The WGSS asks about six basic activities that a person might have difficulty with: seeing, hearing, walking or climbing stairs, remembering or concentrating, washing all over or dressing, and communicating. A person was classified as disabled in the 2023 Census if there was at least one of these activities that they had a lot of difficulty with or could not do at all.

Dataset contains counts for territorial authority local board area (TALB) of usual residence by TALB of usual residence address one year ago and five years ago, and by life cycle age group, for the census usually resident population count, 2023 Census.

​

This dataset compares usual residence at the 2023 Census with usual residence one and five years earlier to show population mobility and internal migration patterns of people within New Zealand.

‘Usual residence address’ is the address of the dwelling where a person considers that they usually live.

‘Usual residence one year ago address’ identifies an individual’s usual residence on 7 March 2022, which may be different to their current usual residence on census night 2023 (7 March 2023).

‘Usual residence five years ago address’ identifies an individual’s usual residence on 6 March 2018, which may be different to their current usual residence on census night 2023 (7 March 2023).

Note: This dataset only includes usual residence address information for individuals whose usual residence address one year ago and five years ago is available at TALB.

​

Life cycle age groups are categorised as:

• under 15 years
• 15–29 years
• 30–64 years
• 65 years and over.

​

This dataset can be used in conjunction with the following spatial files by joining on the TALB code values:

• Territorial authority local board (generalised)

Confidentiality

The 2023 Census confidentiality rules have been applied to 2013, 2018, and 2023 data. These rules protect the confidentiality of individuals, families, households, dwellings, and undertakings in 2023 Census data. Counts are calculated using fixed random rounding to base 3 (FRR3) and suppression of ‘sensitive’ counts less than six, where tables report multiple geographic variables and/or small populations. Individual figures may not always sum to stated totals.

Household crowding

Household crowding is based on the Canadian National Occupancy Standard (CNOS). It calculates the number of bedrooms needed based on the demographic composition of the household. The household crowding index methodology for 2023 Census has been updated to use gender instead of sex. Household crowding should be used with caution for small geographical areas due to high volatility between census years as a result of population change and urban development. There may be additional volatility in areas affected by the cyclone, particularly in Gisborne and Hawke's Bay. Household crowding index – 2023 Census has details on how the methodology has changed, differences from 2018 Census, and more.

The 2006 Census of Tokelau was conducted on the 19th of October 2006, by both local representatives and Statistics New Zealand staff. Significant planning went into both the collection and output phases of the 2006 Census – with consultation on various aspects of the census (for example, questionnaire content consultation) carried out in Tokelau, Samoa and New Zealand, where appropriate. The 2006 Census questionnaire was based on a standard form developed by the Secretariat of the Pacific Community (SPC), with some changes as appropriate to the Tokelau situation.

Tokelau has a unique population composition. A significant proportion of the Tokelauan population are away from the islands at any one time, for various reasons (e.g. healthcare, education). Considerable time and effort has been put into developing effective population measures for the 2006 Census of Tokelau, with a focus on ensuring all usual residents were counted – in particular those who were not present in Tokelau on census night. Core demographic information was completed by the head of the household, on behalf of people who usually live in Tokelau, but were away on census night.

Geographical boundaries

Statistical standard for geographic areas 2023 (updated December 2023) has information about geographic boundaries as of 1 January 2023. Address data from 2013 and 2018 Censuses was updated to be consistent with the 2023 areas. Due to the changes in area boundaries and coding methodologies, 2013 and 2018 counts published in 2023 may be slightly different to those published in 2013 or 2018.

​

Subnational census usually resident population

The census usually resident population count of an area (subnational count) is a count of all people who usually live in that area and were present in New Zealand on census night. It excludes visitors from overseas, visitors from elsewhere in New Zealand, and residents temporarily overseas on census night. For example, a person who usually lives in Christchurch city and is visiting Wellington city on census night will be included in the census usually resident population count of Christchurch city.

​

Caution using time series

Time series data should be interpreted with care due to changes in census methodology and differences in response rates between censuses. The 2023 and 2018 Censuses used a combined census methodology (using census responses and administrative data), while the 2013 Census used a full-field enumeration methodology (with no use of administrative data).

Biological data from the IPY-CAML voyage (TAN0802) by the R/V Tangaroa. The TAN0802 voyage departed from Wellington, New Zealand on Jan 26th 2008 and returned to Wellington, New Zealand, on Mar 21st 2008. The survey was concentrated mainly on the Ross Sea and the waters around Scott and the Balleny Islands. Biological data was collected using a variety of gear, including: bottom trawls, beam trawls, epibenthic sleds, Van Veen grabs, Rosette water bottle and MOCNESS tows. The voyage resulted from a announcement by the Prime Minister in 2007 for new government funding for a New Zealand Census of Antarctic Marine Life (CAML) project to support biodiversity studies in the Southern Ocean and Ross Sea Region as part of the governments Ocean Survey 20/20 (OS2020) programme and the International Polar Year (IPY) activities. The overall Project includes two phases a) data collection voyage and b) data analysis and reporting. The recognition of International Polar Year (IPY) throughout the globe from March 2007 to March 2009 has provided the impetus for a large international effort to conduct collaborative research both in Antarctica and the Arctic, spanning two summer seasons in both regions. New Zealand is participating in a range of both terrestrial and marine projects for IPY that are important, not only nationally, but also in the international science arena. The Census of Antarctic Marine Life (CAML) is a major multi-national IPY Programme that New Zealand’s project is part of. This project forms a particularly important component of the international CAML Programme, as it will not only be part of the circum-polar national surveys, but will provide an opportunity to compare fauna and ecosystems from opposite sides of the globe including the two most significant shelf areas in Antarctica-the Ross Sea and the Weddell Sea.

This report provides a comprehensive analysis of Pasifika communities in Australia based on the 2021 Australian Bureau of Statistics (ABS) Census. The Australian Pasifika Educators Network (APEN) define 'Pasifika' as peoples and communities, who are genealogically, spiritually, and culturally connected to the lands, the skies and seas of the Pasifika region (including Aotearoa, New Zealand), and who have chosen to settle in and call Australia home. This analysis seeks to track key trends that have emerged since the 2015 Pacific Communities report published by Professor Jioji Ravulo based on the 2011 Census. In accordance with the intent of the original report, this current version seeks to provide an understanding of the current demographic, and socioeconomic experiences of Pasifika communities with a particular focus on education. This analysis covers population, education levels, employment patterns, as well as family and household characteristics to not only shed light on the unique circumstances faced by Pasifika communities, but also track key trends over the last decade. In addition, an examination of the Western Sydney region has been included, highlighting the significance of place-based insights on Pasifika communities towards informing policy responses and initiatives. Dataset: OVERVIEW This report compiles data from the 2021 Census of Population and Housing conducted by the Australian Bureau of Statistics (ABS). This document provides the second iteration on the human geography of Pasifika peoples within an Australian context,10 aimed at gathering greater insight into Pasifika communities, as well as comparing and tracing key trends through various datapoints. In addition, this report provides a spotlight on Pasifika communities in Western Sydney, where nearly 20% of the nation’s Pasifika population currently resides.

This dataset compares usual residence at the 2023 Census with usual residence one and five years earlier to show population mobility and internal migration patterns of people within New Zealand.‘Usual residence address’ is the address of the dwelling where a person considers that they usually live.‘Usual residence one year ago address’ identifies an individual’s usual residence on 7 March 2022, which may be different to their current usual residence on census night 2023 (7 March 2023).‘Usual residence five years ago address’ identifies an individual’s usual residence on 6 March 2018, which may be different to their current usual residence on census night 2023 (7 March 2023).Note: This dataset only includes usual residence address information for individuals whose usual residence address one year ago and five years ago is available at TALB.
