“…It is well known from the literature that particular indexes are often used (like the Index of Dissimilarity, the Index of Segregation, the Index of Isolation and the Exposure Index P*). These measures have been exhaustively described by many authors (see, for example, Bell, 1954;Duncan and Duncan, 1955;Taueber and Taueber, 1965;Peach, 1975;Lieberson, 1981;Farley, 1984) though also extensively criticised by others (see, for example, Woods, 1976). Despite the critique, most of the indexes are still in use, probably because of the relative ease with which they can be interpreted.…”

Ethnic Segregation in Cities: New Forms and Explanations in a Dynamic World

Summary. As an introduction to this special issue on ethnic segregation in cities, we offer the readers an overview of the explanatory factors of ethnic segregation and spatial concentration in modern welfare states. After a discussion of the disadvantages and advantages of segregation and concentration, which can be seen as the impetus behind the widespread interest in this topic, we will brie¯y review som e`traditional' theories. That review will be followed by a closer look at behavioural theories and explanations in which constraints are central. The next section will elaborate on restructuring processes, giving special attention to economic change and its effects on cities, groups and spatial arrangements. W e will conclude this introduction with a few remarks on the future of ethnic segregation and concentration and outline some possible directions for future research in this ® eld.

“…In 1955, the differentiation Index D (Index of Dissimilarity) was widely used in the study of residential space differentiation, characterized by a strong representative, of which the role was to measure the differentiation intensity of a certain portion of residential land (Duncan and Duncan, 1955). Here, the value of D ranged between 0 and 1, of which 0 denotes no differentiation, while 1 denotes absolute differentiation.…”

Spatio-temporal differentiation of residential land for coastal town: A case study of Dalian Jinshitan

et al. 2016

Based on SPOT5 satellite remote sensing images and land use data in five time phases covering the period 1988-2012, the distribution characteristics, spatial differentiation processes, and driving mechanisms affecting the residential land of the Jinshitan Tourist Resort were studied. The work included a combination of GIS technology, adoption of the differentiation index D, and the multi-group differentiation-measure model D (m). The results provided a basis for the following conclusions: 1) From 1988 to 2012, the degree of differentiation of the rural residential land first decreased, and then increased. The general residential, commercial residential and garden-house land-types all showed declining trends, of which the garden-house type presented the most intense volatility. 2) The overall background of the traditional residential land type was gradually replaced by a new residential land type, and the total area of residential land increased year by year, significantly improving the overall residential conditions. The areas of the new residential land type showed growth, and were increasingly widely distributed in the coastal tourist resorts, transportation corridors, and scenic areas. 3) Government policy, social differentiation, market mechanisms, and individual choices (along with other factors) were mutually promoted, although still restrained. However, all of these factors interacted to constrain the developmental direction and the processes affecting tourism real estate in the Dalian Jinshitan Tourist Resort.

“…Such measures already exist, developed in the ethnic segregation literature to gauge the extent to which ethnic minority households were concentrated near the city center (Duncan and Duncan 1955;Massey and Denton 1988). Curiously, there has been no recent work that we are aware of that applies centralization indexes to UK data on poverty and no consideration anywhere in the literature, as far as we are aware, to issues of statistical inference for estimates of change in decentralization indexes (see later).…”

“…The measure was first proposed by Duncan and Duncan (1955) and is included in the widely read review by Massey and Denton (1988), which includes it as a measure of minority centralization, one of their five dimensions of segregation along with evenness, exposure, concentration, and clustering. Folch and Rey (2016) recently proposed the RCI as a local measure, applied to each and every aerial unit, to give a moving window of the locus of relative position of one group relative to another.…”
