The share by age maps show the percentage of each age group accounted for by each ethnic group. The ethnic share maps show the percentage of the total population accounted for by each ethnic group. The ethnic overcount maps show the extent to which ethnic group responses for each broad age group and each area exceed head count (that is, the extent to which people are counted into more than one ethnic group). Notably, the lower the age group, the higher the ethnic overcount, and vice-versa, reflecting increasing levels of intermarriage and partnering over time.

These data have been drawn from Statistics New Zealand NZStat (Subnational ethnic population projections 2013(base)-2038, medium variant) and converted for visualisation by the CaDDANZ Population Atlas research team.
