The older age structure of the European groups in New Zealand is a reflection of the fact that many of their members migrated to New Zealand following the Second World War and that their children possibly no longer identify with the ethnic group of their parents.
新西兰欧裔群体年龄较高，这一结构表明，许多人是在第二次世界大战之后移民到新西兰，而他们的子女很可能不再确认属其父母的族裔群体。
