Rationale

As leaders of the Official Statistics System (OSS), Statistics New Zealand has developed a statistical standard for the collection and dissemination of data on gender identity. The objectives of the statistical standard for gender identity are to:

  • standardise definitions and measures of gender identity data across the OSS, to improve accessibility, interpretability, and comparability of data, and reduce duplication of effort 
  • meet human rights requirements for data collection and to support the legal requirements of the Human Rights Act 1993 
  • enable policy-makers to develop measures that will address matters of importance affecting gender minority groups. This will more adequately address the needs of these people across the gender identity spectrum in areas such as health, social, education, and employment.

Classification of gender identity

The standard classification of gender identity is a hierarchical classification of two levels. Level 1 of the classification has three categories. Level 2 has six categories.

Classification of gender identity

  1. Male
    11   Male / Tāne
