Modelling residential segregation as unevenness and clustering
Traditional studies of residential segregation use a descriptive index approach with predefined spatial units to report the degree of neighbourhood differentiation. We develop a model-based approach which explicitly includes spatial effects at multiple scales, recognising the complexity of the urban environment while simultaneously distinguishing segregation at each scale net of all other scales. Moreover, this model distinguishes segregation as …
Implementing a Multilevel Index of Dissimilarity in R with a case study of the changing scales of residential ethnic segregation in England and Wales
This paper introduces the Multilevel Index of Dissimilarity package, which provides tools and functions to fit a Multilevel Index of Dissimilarity in the open source software, R. It extends the conventional Index of Dissimilarity to measure both the amount and geographic scale of segregation, thereby capturing the two principal dimensions of segregation, unevenness and clustering. The statistical basis for the multilevel approach is discussed, ma…
Macro‐scale stability with micro‐scale diversity
Most studies of ethnic residential segregation that address the issue of spatial scale make it implicit – if not explicit – that segregation is greater at smaller than larger scales. Such studies, however, invariably measure segregation separately at those scales, and take no account of the fact that measures at the smaller scale necessarily incorporate that at any larger scales. The present paper rectifies that situation by, for the first time, …
Ethnic Residential Segregation
We develop and apply a multilevel modeling approach that is simultaneously capable of assessing multigroup and multiscale segregation in the presence of substantial stochastic variation that accompanies ethnicity rates based on small absolute counts. Bayesian MCMC estimation of a log-normal Poisson model allows the calculation of the variance estimates of the degree of segregation in a single overall model, and credible intervals are obtained to …
Macro-, Meso- and Microscale Segregation
Most world cities can now be characterized as multiethnic and multicultural in their population composition, and the residential patterning of their major component ethnic groups remains a topic of substantial research interest. Many studies of the degree of residential segregation of ethnic groups recognize that this is multiscalar in its composition, but few have incorporated this major feature into their analyses: Those that do mostly conclude…
The melting-pot and the economic integration of immigrant families
The melting-pot argument, whereby economically heterogeneous multi-cultural societies, characterised by high levels of immigration from a variety of origins, become more homogeneous over time, has attracted much attention, especially in North America. Australia has similarly experienced major waves of immigration from a wide range of cultural backgrounds. This paper reports successful tests of hypotheses, derived from the melting-pot model, that …

The Resource of Ethnicity in the Housing Careers and Preferences of the Vietnamese Communities in London
This paper briefly outlines the housing careers of Vietnamese households since their arrival in the UK in the late 1970s and draws on a series of focus groups to examine the role that ethnicity has played, and may continue to play, in their housing careers. It notes that the first arrivals lacked the infrastructure of an existing Vietnamese community in the UK and were further disadvantaged by the dispersal policy adopted by the voluntary agencie…
