Using spatial statistics to identify and characterise ethnoburbs: Establishing a methodology using the example of Auckland, New Zealand

Recent studies in the United States and other Pacific Rim countries have identified a new form of ethnic minority group clustering within the residential mosaic-ethnoburbs. These are suburban in location, occupied by relatively high-income, predominantly Asian, immigrants, and low density in their nature: many migrants move directly to those suburbs rather than the inter-generational outward migration from central city clusters typical of other migrant streams. Although ethnoburb residents tend to cluster in particular segments of the built-up area they do not to form large percentages of the population there. As yet, no methodology has been developed to identify these clusters, as a prelude to identifying their characteristics. This paper offers such a procedure, based on local statistical analysis. It is applied to six Asian groups in Auckland, New Zealand.
