About the estimated resident population measure

The estimated resident population provides the best measure of how many people live in a given area at a given date.

After each census a new estimated resident population base is derived using the census usually resident population count with adjustments for:

  • non-response to the census ethnicity question
  • net census undercount (as measured by a post-enumeration survey)
  • residents temporarily overseas on census night
  • births, deaths, and net migration between census night and 30 June
  • reconciliation with demographic estimates at the youngest ages.

The estimated resident population is not directly comparable with the census usually resident population count because of these adjustments.

We use the base populations in the production of post-censal population estimates and projections. In order to facilitate comparisons between the base populations at 30 June 1996, 2001, 2006, and 2013, we have applied the same ethnic groups and subnational area boundaries to each base population. For more information see Variables.

Variables

Ethnicity

Ethnicity is the ethnic group or groups that people identify with or feel they belong to. Ethnicity is a measure of cultural affiliation, as opposed to race, ancestry, nationality, or citizenship. Ethnicity is self-perceived and people can belong to more than one ethnic group.

Estimates are available for five broad ethnic groups:

  1. European or Other ethnicity (including New Zealander)
  2. Māori
  3. Pacific peoples
  4. Asian
  5. Middle Eastern/Latin American/African.

It is important to note that these ethnic groups are not mutually exclusive because people can and do identify with more than one ethnicity. People who identify with more than one ethnicity have been included in each ethnic group.

The 'Māori', 'Pacific peoples', 'Asian' and 'Middle Eastern/Latin American/African' ethnic groups are defined in Level One of the Standard Classification of Ethnicity 2005. The estimates for the 'European or Other ethnicity (including New Zealander)' group include people who belong to the 'European' or 'Other ethnicity' groups defined in Level One of the standard classification. If a person belongs to both the 'European' and 'Other ethnicity' groups they have only been counted once. Almost all people in the 'Other ethnicity' group belong to the 'New Zealander' sub-group.

The 1996 and 2001 estimates were based on the Standard Classification of Ethnicity 1996. In order to facilitate comparisons, the 1996, 2001, 2006, and 2013 estimates have been classified to the five broad ethnic groups shown above. The relationship between these five broad ethnic groups, and the ethnic groups outlined in the 1996 classification, are shown below.

Ethnic group in present tables    Ethnic group defined in Level One of the Standard Classification of Ethnicity 1996
 European or Other ethnicity (including New Zealander)  European
 Māori  Māori
 Pacific peoples  Pacific peoples
 Asian  Asian
 Middle Eastern/Latin American/African  Other Ethnicity

Data users need to exercise caution while interpreting ethnic data. People can identify with different ethnic groups over time. In addition, changes in questionnaire design, classification, and coding practice have resulted in some data that is not consistent between 1996, 2001, 2006, and 2013. Particular caution needs to be exercised while interpreting population estimates for the 'European or Other ethnicity' and 'Māori' ethnic groups at 30 June 1996, which were affected by a questionnaire change in the 1996 Census. For further information refer to 2006 Census Information About Ethnicity or the Ethnicity Technical Support Papers.

Users also need to be aware that an annual time series of Māori population estimates is available from 1991. We produce this time series using a different method. For this reason, the estimates of the Māori population at 30 June 1996 differ from the estimates provided in these population base tables.

Information about rounding

Within the tables, individual figures may not sum to stated totals due to rounding.

We determine the rounding of figures based on the total population size of the geographic area. The rounding rules that have been applied are shown below.

Total population size of geographic area   Rounding of single year of age and five-year age group cells  Rounding of broad age group and total (all ages) cells
 Less than 2,000  5 10 
 2,000 to 9,999  10  10
 10,000 to 19,999  10  50
 20,000 or more  10  100

For example, if a geographic area has a population of 15,000 then single year of age and five-year age group cells will be rounded to the nearest 10, and broad age group and total (all ages) cells will be rounded to the nearest 50.
