Maternity - Birth rate by age group 2005–2014

Ministry of Health


Reproductive age refers to females aged 15─44 years.


Deprivation quintiles are based on the area of residence for the woman or baby. They range from 1 (least deprived) to 5 (most deprived), according to the 2006 New Zealand Deprivation Index. Approximately equal numbers of the population reside in areas associated with each of the five deprivation quintile areas.

Data calculation/treatment

This publication uses prioritised ethnicity, whereby each person represented in the data is allocated to a single ethnic group using the priority system Māori > Pacific peoples > Asian > European > Other. The aim of prioritisation is to ensure that where it is necessary to assign people to a single ethnic group, ethnic groups that are small or important in terms of policy are not swamped by the European ethnic group.
