Auckland, the largest city of New Zealand, is one of the most diverse cities in the world, with more than 40% of its population born abroad, more than 200 ethnicities represented and 160 languages spoken. In this paper, we measure residential sorting of individuals in Auckland by their cultural (ethnicity) and economic (income, education and occupation) characteristics for the years 1991–2013. Using entropy-based measures of residential sorting and of neighbourhood diversity, we find that individuals exhibit greater residential sorting by ethnicity than by economic characteristics. Geographically, the semi-rural fringes of the city exhibit less diversity than the central urban area. Multi-group indexes of cultural and economic sorting showed a small decline over the 1991–2013 period. We also observe that ethnic sorting declined over that period for broad ethnic groups, but that sorting within the broad ethnic groups increased since 2001. A similar pattern of decreasing sorting at the aggregate level, with increasing sorting within groups in the more recent sub-period, is observed for occupations.

奥克兰是新西兰最大的城市，是世界上最多样化的城市之一，其40％以上的人口出生在国外，有200多个种族和160种语言使用。在本文中，我们通过其1991-2013年间的文化（种族）和经济（收入，教育和职业）特征来衡量奥克兰居民的住房分类。使用基于熵的住宅分类和邻里多样性的测度，我们发现个人通过种族比经济特征表现出更大的住宅分类。从地理上看，城市的半农村边缘地区比市中心地区具有更少的多样性。在1991-2013年期间，文化和经济分类的多组指标显示出小幅下降。自2001年以来，各民族之间的分类有所增加。在职业的总分类水平上，减少了相似的模式，在最近的子时期中，各组内部的分类也有所增加。
