New Zealand is culturally diverse. Even at a regional level, there are big differences in ethnic composition… and with an increasingly inter-connected world, ethnic composition is expected to change substantially in the future, particularly in Auckland.

Statistics New Zealand has provided us with sub-national ethnic population projections, by age and sex, from 2013 to 2038 which are well suited to visualisation using stacked area charts. The package ggplot2 in R makes generating these easy.

The following projections assume ‘medium fertility, medium paternity, medium mortality, medium net migration, and medium net inter-ethnic mobility.’ This is considered ‘medium growth’*.
