ethnicNZ

Format ethnicity data collected via the New Zealand census questionnaire.

As stated on the Stats NZ website

Ethnicity is a measure of cultural affiliation. It is not a measure of race, ancestry, nationality, or citizenship. Ethnicity is self perceived and people can belong to more than one ethnic group.

Capturing ethnicity

In research, ethnicity is typically captured using the Standard Ethnicity Questionnaire as used in the Census.

Reporting ethnicity

The New Zealand Ministry of Health recommends that:

Where thereare multiple ethnicities for a respondent, one of the following three methods of output must be used: a) total response (overlapping) b) prioritised (the most common form of output in the health and disability sector) c) sole/combination.

Total response

When reporting ethnicity as total response, the StatsNZ Level 1 codes are typically used.
