Measures of Spatial Segregation

The measurement of residential segregation patterns and trends has been limited by a reliance on segregation measures that do not appropriately take into account the spatial patterning of population distributions. In this paper we define a general approach to measuring spatial segregation among multiple population groups. This general approach allows researchers to specify any theoretically based definition of spatial proximity desired in computing segregation measures. Based on this general approach, we develop a general spatial exposure/isolation index (̃*), and a set of general multigroup spatial evenness/clustering indices: a spatial information theory index (̃), a spatial relative diversity index (̃), and a spatial dissimilarity index (̃). We review these and previously proposed spatial segregation indices against a set of eight desirable properties of spatial segregation indices. We conclude that the spatial exposure/isolation index ̃*—which can be interpreted as a measure of the average composition of individuals' local spatial environments—and the spatial information theory index ̃—which can be interpreted as a measure of the variation in the diversity of the local spatial environments of each individual—are the most conceptually and mathematically satisfactory of the proposed spatial indices.     

Rethinking empirical approaches to racial segregation

Within empirical approaches to racial residential segregation, there has been a tendency to draw on the work of or influenced by Robert E. Park and his ecological hypothesis to explore social and spatial relations between members of different ethnic and racial groups, thus framing research within a race relations paradigm. This has promoted an analysis which naturalizes racial differences but which also sidelines structural considerations. In turn this approach has also fed into political discourses on segregation, at times supporting more reactionary positions. This paper seeks to address this debate by considering whether emphasis on minority ethnic concentration sidelines the more pertinent issue of concentration in deprived areas, suggesting that neighbourhood deprivation as a measure can be more easily aligned with structural conditions which have influenced the settlement and historical experience of many ethnic minority communities. Specifically, I consider the extent to which a measure of neighbourhood deprivation is more important than the ethnic composition of an area for thinking about the distribution of inequalities in unemployment (as one example of socio‐economic inequality). Using multilevel logistic regression I find neighbourhood income deprivation to be more important than levels of co‐ethnic concentration for explaining ethnic differences in unemployment. The findings imply that neighbourhood deprivation is significantly more important for considering inequalities in unemployment for ethnic minorities than the ethnic composition of an area.     

Being Han in a multi-ethnic region of the People’s Republic of China

This article draws on ethnographic material collected in Yangzong county of Yunnan, a province well known for its ethnic diversity. It deals with how the members of this peripheral Han population are categorised by others and by themselves in relation to minority groups and notions of Chinese identity. The specificity of the Han of Yangzong is framed by an ongoing tension between two contrasting points of view: they appear both as a local ethnic minority among others, and, notably by means of ritualised theatrical representations, as the legitimate representatives of the national majority. The Han people of Yunnan, who represent two-thirds of the province’s population, have been largely ignored by contemporary research. However, this study sheds light on the necessary interplay of different levels of identity and asserts the understanding of the category of ‘Han’ as perceived by the Chinese State as well as by the local people.     

ETHNIC DIVERSITY, SEGREGATION, AND INEQUALITY: A Structural Model of Ethnic Prejudice in Bosnia and Croatia

Widespread ethnic prejudice is an incomplete explanation for the development of war in the former Yugoslavia. However, high levels of prejudice in ethnic enclaves played an important role in increasing ethnic tensions and facilitating the outbreak of war. The purpose of this article is to explain county differences in average levels of ethnic prejudice in Bosnia and Croatia prior to the wars of national separation. We focus on structural characteristics of counties, such as ethnic diversity, economic conditions, and ethnic segregation and inequality, to explain county differences in average levels of prejudice. We also consider the possibility that compositional differences among counties (e.g., differences in average levels of education) explain county differences in ethnic prejudice. We combine survey data and county-level census data collected immediately prior to the wars of national separation and use hierarchical linear modeling techniques to analyze these data. Results suggest that ethnic diversity and ethnic occupational segregation decrease ethnic prejudice while ethnic economic inequality increases ethnic prejudice. Thus, structural characteristics account for some of the county differences in average levels of prejudice. County compositional differences, however, explain a majority of the county variation in ethnic prejudice. These results provide important clues to the origins of pockets of intense ethnic prejudice within diverse societies.     

The effects of racial/ethnic segregation on Latino and Black homicide

Racial/ethnic residential segregation has been shown to contribute to violence and have harmful consequences for minority groups. However, research examining the segregation–crime relationship has focused almost exclusively on blacks and whites while largely ignoring Latinos and other race/ethnic groups and has rarely considered potential mediators (e.g., concentrated disadvantage) in segregation–violence relationships. This study uses year 2000 arrest data for California and New York census places to extend segregation–crime research by comparing the effects of racial/ethnic residential segregation from whites on black and Latino homicide. Results indicate that (1) racial/ethnic segregation contributes to both Latino and black homicide, and (2) the effects for both groups are mediated by concentrated disadvantage. Implications for segregation–violence relationships, the racial-invariance position, and the Latino paradox are discussed.     

Emerging Patterns of Hispanic Residential Segregation: Lessons from Rural and Small‐Town America

The past two decades have ushered in a period of widespread spatial diffusion of Hispanics well beyond traditional metropolitan gateways. This article examines emerging patterns of racial and ethnic residential segregation in new Hispanic destinations over the 1990–2010 period, linking county, place, and block data from the 1990, 2000, and 2010 decennial censuses. Our multiscalar analyses of segregation are framed by classical models of immigrant assimilation and alternative models of place stratification. We ask whether Hispanics are integrating spatially with the native population and whether recent demographic and economic processes have eroded or perpetuated racial boundaries in nonmetropolitan areas. We show that Hispanic residential segregation from whites is often exceptionally high and declining slowly in rural counties and communities. New Hispanic destinations, on average, have higher Hispanic segregation levels than established gateway communities. The results also highlight microscale segregation patterns within rural places and in the open countryside (i.e., outside places), a result that is consistent with emerging patterns of “white flight.” Observed estimates of Hispanic‐white segregation across fast‐growing nonmetropolitan counties often hide substantial heterogeneity in residential segregation. Divergent patterns of rural segregation reflect local‐area differences in population dynamics, economic inequality, and the county employment base (using Economic Research Service functional specialization codes). Illustrative maps of Hispanic boom counties highlight spatially uneven patterns of racial diversity. They also provide an empirical basis for our multivariate analyses, which show that divergent patterns of local‐area segregation often reflect spatial variation in employment across different industrial sectors.     

Racial residential segregation and the concentration of low- and high-income households in the 45 largest U.S. metropolitan areas

"The objectives of this paper are to determine the relationship between racial residential segregation and (1) the spatial concentration of low- and high-income households, and (2) the socioeconomic characteristics of racial minority households. The three largest racial minority groups are compared (blacks, Hispanics, and Asians) in the largest 45 metropolitan areas in the United States. Data were obtained from the U.S. bureau of the Census' Population and Housing Summary Tape files. The results revealed that residential segregation of blacks was distinctly different from Asians and Hispanics. Moreover, for Asians and Hispanics, their socioeconomic characteristics matter in their level of residential segregation. For black households, however, their socioeconomic characteristics matter little."     

The relationship between faculty diversity and graduation rates in higher education

This study examines the relationship between faculty racial/ethnic diversity and graduation rates of undergraduate students, in particular those from underrepresented racial and ethnic minority populations. Using IPEDS data, the researchers calculated a Diversity Score for each institution. Findings suggest U.S. faculty diversity is lower than in the U.S. national population. Overall graduation rates for underrepresented minority students of all races/ethnicities are positively affected by increased diversity of their faculty.     

Effekte der Gruppengröße auf die Arbeitsmarktintegration von Migranten

Some ethnic minorities tend to be less successful in the German labour market compared to the indigenous population even when controlling for relevant resources. The paper uses data from the German Mikrozensus to investigate to what extent the remaining ethnic disadvantages can be explained by relative minority group size. On theoretical grounds, ethnic concentration can have an impact on the members of the own minority as well as on members of other ethnic groups. The paper finds empirical evidence that a strong ethnic concentration impedes structural assimilation of Turkish migrants with a higher level of education, as the ethnic mobility trap model would suggest. However, the share of the Turkish population in a county does not only have an impact on the labour market performance of Turkish migrants (endogenous effect) but also affects the economic success of Italians and Germans (exogenous effects). The empirical results indicate, that controlling for regional concentration can – at least for some minority groups and to some extent – explain remaining ethnic disadvantages.     

Segregation,ethnic labour market and the occupational expectations of Palestinian students in Israel

Using data from a large national representative survey of Palestinian high school students in Israel, this study examines the effect of the local labour market and the internal ethnic/religious segregation between Muslims, Christians and Druze, on students' occupational expectations. The data, which were collected in spring 1997, consisted of two types, these being data regarding students, and data regarding schools. The findings show that despite the disadvantages of the Palestinian minority as a whole within Israeli society, students tend to develop high occupational expectations. While the general level of their expectations can be explained by their educational and residential segregation from the Jewish majority, the multi-level analyses suggests that the internal segregation facilitates differential access to socio-economic resources, which generate different levels of occupational expectations between students from various ethnic/religious groups. More specifically, the findings demonstrate that the social and economic differences between Muslims, Christians and Druze are playing a central role in determining students' expectations, acting as a mechanism to preserve social inequality. The gender dimension of the occupational expectations and the influence of die segregation between Palestinian and Jewish students, are also discussed.     

Minority schooling and intercultural education: a comparison of recent developments in the old and new EU member states

Comparative reports conducted by the author show different educational approaches concerning the schooling of ethnic minorities in the EU Member States as well as differences in the handling of issues of cultural diversity. Minority schooling in the new EU Member States primarily focuses on the education of national or autochthonous minority groups, in contrast to the old EU Member States, where language and compensatory programs for migrant minority students have been of main concern. In addition, there are also different conceptions of intercultural education in the respective countries. Differences in school achievement of various ethnic groups can be identified despite limited differential data on educational attainment in many countries. This paper addresses two main questions: first, in which ways can different educational approaches be effective in raising the educational attainment of ethnic minorities? Second, in which ways could they be most suitable for preparing all students for living in a culturally diverse society and to encourage tolerance towards cultural differences?     

Acculturation and school success: A study among minority youth in the Netherlands

In this study, we examine the school performance and school adjustment of youth from three different minority groups: Turkish and Moroccan labor migrants, and Christian-Turkish refugees. We compare these groups with their native Dutch peers in secondary school settings. The aim of the study was to test cultural explanations of ethnic differences in success and well-being in school. Acculturation attitudes were a central focus in the study and were viewed as a possible explanatory ground for ethnic diversity in educational profiles. With regard to school adjustment, our findings suggest highly selective acculturation effects for specific ethnic groups in specific contexts (home vs. school). We found that acculturation effects are highly context-dependent.     

Spatial Segregation and Social Differentiation of the Minority Nationalities from the Han Majority in the People's Republic of China

One of sociological human ecology's classic hypotheses posits the existence of a positive relationship between social status and residence. The more similar the social characteristics of two populations, the greater their degree of residential propinquity. This study examines that hypothesis with data for the Han majority and each of the fifty-five minority nationalities enumerated in the 1982 Census of the People's Republic of China. We find support for the hypothesis when we use a segregation measure that reflects the degree of unevenness of the residential distribution of a minority population from the Han. The paper also addresses the implications of these findings for the social and economic development of the Chinese minorities.     

Ethnic patterns in the phonetics of Montreal English

Most North American cities no longer display strong ethnic differentiation of speech within the European‐origin population. This is not true in the English‐speaking community of Montreal, Canada, where English is a minority language. Differences in the phonetic realization of vowels by Montrealers of Irish, Italian, and Jewish ethnic origin are investigated by means of acoustic analysis. A statistical analysis of ethnic differences in formant frequencies shows that ethnicity has a significant effect on several variables, particularly the phonetic position of /u:/ and /ou/ and the allophonic conditioning of /æ/ and /au/ before nasal consonants. The unusual tenacity of ethnophonetic variation in Montreal English is explained in light of the minority status of English, and the social and residential segregation of ethnic groups in distinct neighborhoods, which limits their exposure to speakers of Standard Canadian English who might otherwise serve as models for assimilation.     

Metropolitan Heterogeneity and Minority Neighborhood Attainment: Spatial Assimilation or Place Stratification?

Using geo-referenced data from the Panel Study of Income Dynamics, in conjunction with decennial census data, this research examines metropolitan-area variation in the ability of residentially mobile blacks, Hispanics, and whites to convert their income into two types of neighborhood outcomes-neighborhood racial composition and neighborhood socioeconomic status. For destination tract racial composition, we find strong and near-universal support for the "weak version" of place stratification theory; relative to whites, the effect of individual income on the percent of the destination tract population that is non-Hispanic white is stronger for blacks and Hispanics, but even the highest earning minority group members move to tracts that are "less white" than the tracts that the highest-earning whites move to. In contrast, for moves into neighborhoods characterized by higher levels of average family income, we find substantial heterogeneity across metropolitan areas in minorities' capacity to convert income into neighborhood quality. A slight majority of metropolitan areas evince support for the "strong version" of place stratification theory, in which blacks and Hispanics are less able than whites to convert income into neighborhood socioeconomic status. However, a nontrivial number of metropolitan areas also evince support for spatial assimilation theory, where the highest-earning minorities achieve neighborhood parity with the highest-earning whites. Several metropolitan-area characteristics, including residential segregation, racial and ethnic composition, immigrant population size, poverty rates, and municipal fragmentation, emerge as significant predictors of minority-white differences in neighborhood attainment.     

Racial and Ethnic Residential Patterns in Canada

The aim of this study is to understand how city factors explain racial and ethnic residential patterns in contemporary multiethnic cities. We examined residential patterns among 17 groups in 12 Canadian cities. The results suggest that we should be cautious in taking factors derived from literature based largely on European experiences at the beginning of the last century and applying them uniformly to different groups in Canadian multiethnic cities. Our results show that the residential segregation of different racial and ethnic groups is affected by different sets of city factors. In addition, most factors suggested in that literature do not relate to the segregation patterns among visible minority groups.     

THE COURSE OF RESIDENTIAL SEGREGATION: Ethnicity, Socioeconomic Status, and Suburbanization in Israel

As is well documented, today, 40 years after the establishment of statehood, ethnicity figures importantly in determining educational and occupational attainment in Israel. The present study measures residential patterns to examine the relevance of ethnic differences in generating social distance.
Census data on the Jewish population and pairs of ethnic groups depict residential pattern changes in the central city and suburban ring for the largest metropolitan area, Tel Aviv, in 1972 and 1983. Segregation patterns are moderate in the central city, low in the suburban ring; in both localities, moreover, segregation declines during the decade studied. Although ethnicity significantly affects a group's separation, its relative importance declines. With Socioeconomic status, ethnicity, and other intervening variables controlled, Jewish ethnic groups' attainments significantly differ by locale: Suburban residence increases spatial assimilation.     

ESTIMATING NET INTERRACIAL MOBILITY IN THE UNITED STATES: A RESIDUAL METHODS APPROACH

This paper presents a residual methods approach to identifying social mobility across race/ethnic categories. In traditional demographic accounting models, population growth is limited to changes in natural increase and migration. Other sources of population change are absorbed by the model residual and can be estimated only indirectly. While these residual estimates have been used to illuminate a number of elusive demographic processes, there has been little effort to incorporate shifts in racial identification into formal accounts of population change. In light of growing evidence that a number of Americans view race/ethnic identities as a personal choice, not as a fixed characteristic, mobility across racial categories may play important roles in the growth of race/ethnic subpopulations and changes to the composition of the United States. To examine this potential, we derive a reduced-form population balancing equation that treats fertility and international migration as given and estimates survival from period life table data. After subtracting out national increase and net international migration and adjusting for changes in racial measurement and census coverage, we argue that the remaining error of closure provides a reasonable estimate of net interracial mobility among the native born. Using recent U.S. Census and ACS microdata, we illustrate the impact that identity shifts may have had on the growth of race/ethnic subpopulations in the past quarter century. Findings suggest a small drift from the non-Hispanic white population into race/ethnic minority groups, though the pattern varies by age and between time periods.     

Measuring ethnic polarization

An ethnic polarization index is a measure of the extent to which individuals in a population are distributed across different ethnic groups. The objective of this article is to develop some characterizations of the Reynal-Querol (RQ) index of ethnic polarization using alternative sets of independent axioms. A generalized form of RQ is also characterized. Some implications of the axioms are investigated as well.
