The graph above shows the ages at which most people die have steadily risen over the past 130 years. Mortality rates increased as infectious diseases, which tended to kill large numbers of children and young adults, were gradually eradicated. The Māori population felt this impact from around the mid-20th century – much later than non-Māori.
The distribution of deaths presented in the graph is based on the number dying at each age sourced from period life tables maintained by Statistics New Zealand. The tables allow comparison of hypothetical death numbers between populations with very different age compositions – such as Māori and non-Māori.
