Student Population: Age

The Ministry uses school roll data in a number of ways: to fund and staff schools; to support policy analysis, development, and decision making; to monitor the outcomes of the New Zealand education system; and for national and international reporting purposes.

The roll data presented here is based on the 1 July roll returns. The data includes gender, ethnic group, funding year level, and age.  A small amount of trend information is also available.

Identical information is available by regional council  and territorial local authority through the Know Your Region pages.

Alternatively a large amount of roll data is available from our statistical pages.  See July School Roll Returns.

Notes:

  1. Ethnicity is multiple response, that is, students who affiliated in more than one ethnic group have been counted in each ethnic group. Students are only counted once in the total, therefore, the ethnic groups may not sum to the total.
  2. MELAA (Middle Eastern, Latin American, and African) students.
