Residential segregation is often considered to be one of the social problems that intensify urban inequality This study reviews three different frameworks about the causes of residential segregation and tests their validity in the real world. The review focuses on racial/ethnic residential segregation in U.S. cities since it has been blamed for persistent socio-economic gap among racial/ethnic groups. The three different segregation frameworks include 'spatial assimilation' that attributes segregation to low degree of assimilation and acculturation, 'place stratification' to discriminatory practices in the housing and mortgage markets such as steering, blockbusting, and redlining, and 'resurgent ethnicity' to racial/ethnic preference in residential choice, particularly in-group attraction. As an effort to test their validity, the paper examined residential pattern changes of the four major Asian nationality groups through 1990s and found that their residences got decentralized but re-cluster in some selected suburbs. This supports 'resurgent ethnicity' largely and 'spatial assimilation' only partly.

This paper offers a brief overview of the historical implications of residential segregation in Busan, Korea. It first reviews the history of residence from the early 1900s to the present and the transition of residential boundary of the City of Busan. It then considers the characteristics of residential segregation and the important factors in it. The social class of pre-industrial society led the inequality of residential areas around the Eubchee. The existed Korean residential areas were separated by newly built-up residential areas in the Japanese colonial era. After the liberation from Japanese Rule and Korean War, rapid population growth made considerable slums across the City of Busan. These slums were an important factor to segregate residential areas from prosperous areas ever afterward. The socio-economic status has related to residential segregation through the formation of differential housing classes since 1990s. The historial analysis of these periods will offer an insight into how the dominant factors lead residential segregation in a specific period by promoting a more socio-economically integrated society.

Residential differentiation is an academic theme which has been given enormous attention in urban studies. This is due to the fact that residential segregation can be seen as one of the best indicators for socio-spatial dialectics occurring on urban space. Measuring how one population group is differentiated from the other group in terms of residential space has been a focal point in the residential segregation studies. The index of dissimilarity has been the most extensively used one. Despite its popularity, however, it has been accused of inability to capture the degree of spatial clustering that unevenly distributed population groups usually display. Further, the spatial indices of segregation which have been introduced to edify the problems of the index of dissimilarity also have some drawbacks: significance testing methods have never been provided; recent advances in spatial statistics have not been extensively exploited. Thus, the main purpose of the research is to devise a spatial separation measure which is expected to gauge not only how unevenly two population groups are distributed over urban space, but also how much the uneven distributions are spatially clustered (spatial dependence). The main results are as follows. First, a new measure is developed by integrating spatial association measures and spatial chi-square statistics. A significance testing method based on the generalized randomization test is also provided. Second, a case study of residential differentiation among groups by educational attainment in major Korean metropolitan cities clearly shows the applicability of the analytical framework presented in the paper.

It is widely believed that increasing socio-economic polarization inspired by globalization and economic restructuring worsens residential segregation by class in Korean cities. However, the existing literature falls short in showing the recent changes of the residential segregation, particularly after the 1997 financial crisis, with reliable and systematic segregation measures. Noting that there are the two major dimension in residential segregation - evenness-concentration and exposure-clustering - this study introduced not only global measure (dissimilarity index and isolation/interaction index) but also local measures (location quotient and Local Moran's I) for each dimension. These measures are applied to the case study of Seoul in the 2000s. The class is defined by education attainment and the data is obtain through the MicroData System Service System(MDSS). The result shows that the residential segregation by education attainment persists through 2000s and even get worse in some dimension. More significantly, it turns out that high-class and low-class residence are nearly mirror-images of each other, indicating high segregation.

Housing market is segmented through 1) housing supply classified by housing characteristics and 2) housing demand classified by different housing opportunity of household. Moreover, neighborhood plays a role in intensifying housing market segmentation as a factor affecting on decision making relevant to housing supply and demand. while segmented housing markets have different mechanism, existing studies on residential differentiation and housing market have overlooked the characteristic differences among housing submarkets as the studies presume metropolitan housing market to be a single housing market. while the concept of 'residential differentiation' pays much attention on spatial pattern after the ecological approach appeared, the concept of ‘housing submarkets' is explanatory of the process of urban space structure formation. Analysis on housing submarkets makes up for the weak points of the behavioral approach inquiring into socio-economic constraint and different housing opportunity of household.

The main purpose of the research is to illustrate the value of the spatial statistical approach to residential differentiation by providing a framework for exploratory spatial data analysis (ESDA) using a local spatial separation measure. ESDA aims, by utilizing a variety of statistical and cartographic visualization techniques, at seeking to detect patterns, to formulate hypotheses, and to assess statistical models for spatial data. The research is driven by a realization that ESDA based on local statistics has a great potential for substantive research. The main results are as follows. First, a local spatial separation measure is correspondingly derived from its global counterpart. Second, a set of significance testing methods based on both total and conditional randomization assumptions is provided for the local measure. Third, two mapping techniques, a 'spatial separation scatterplot map' and a 'spatial separation anomaly map', are devised for ESDA utilizing the local measure and the related significance tests. Fourth, a case study of residential differentiation between the highly educated and the least educated in major Korean metropolitan cities shows that the proposed ESDA techniques are beneficial in identifying bivariate spatial clusters and spatial outliers.

Social and population geography in Korea has been developed somewhat later than other special subjects of geography. But in recent years, it has attracted much interests of geographers, and accumulated a considerably large amount of research products. Seen in this context, it is resonable to expect that social and population geography will not only lead the development of geography in the future, but also contribute to the resolution of socio-spatial problems in Korea. From this point of view, we shall retrospect in this paper the progress of social and population geography in Korea since the 1950s, and look out its future prospect and further research tasks. In the first place, we discuss general concepts and major themes of social and population geography, and overview its development process, and than review in more details some important research products which would be categorized into five main subjects, that is, research methodology, urbanization and urban population phenomena, population movement and changing rural life, residential differentiation and urban redevelopment, and urban social life and regional social well-being. Finally, we consider briefly the future prospect and further tasks of social and population geography in Korea.

Purpose: Residential differentiation is often considered to be one of the social problems that intensify urban inequality. The purpose of the study was to analyze the changes in the Gwangju urban landscape due to foreign inflows after reviewing the different frameworks about the causes of residential segregation and verifying compliance through case analysis. Method: This study analyzed the increase of Gwangju Foreign Population based on the data of the Statistics Korea and derived the concentrated areas of foreign population using GIS program. Then through the field research around the target areas, the changes of urban landscape by the foreign residents was analyzed. The foreign population in Korea recently surpassed 1.5 million is expected to increase further, and has already raised numerous social issues especially in urban area. Result: Therefore, basic and systematic analyses on foreign population and its impacts on urban residential landscape are necessary to resolve the issues. Since Gwangju is also in a similar situation, this research is first, to address the current situation and identify the problem, and then to suggest the directions for resolving them. It is also expected to be helpful provide a basic reference for related further researches.

It has been widely believed that the ethnic relations in Honolulu and Hawai'i in the early twentieth century were little associated with racist ideology because the white race was minority in terms of the racial composition. In reality, however, the racial and ethnic issues have played a major role in forming the past and present relations among ethnic groups. This study shows that the white-supremacy ideology exerted a strong influence on minority groups in Honolulu throughout the immigration and settling-down process, as much as in the mainland U.S. Clear occupational stratification and residential segregation among the ethnic groups in Honolulu represented almost the same situation as in mainland cities. The social segregation and spatial propinquity of their residential neighborhoods facilitated the construction of dichotomized identity: "Local" versus "Haole". Such transformed identities were a product of on-going inter-ethnic negotiation process embedded in the non-white multi-ethnic neighborhoods.

1997년 IMF 경제위기 이후 한국사회의 뚜렷한 변화의 하나는 빈부격차의 확대와 함께 사회계층의 양극화가 진행되고 있다는 점이다. 이 논문의 목적은 사회적 양극화의 주요 원인은 무엇이며, 사회적 양극화가 공간적으로는 어떻게 나타나는가를 서울을 사례로 하여 규명하는 데 있다. 서구 선진자본주의 국가에서 사회적 양극화에 대한 논의는 이미 1990년대 초 세계화 또는 세계도시가 주요한 연구주제로 등장하면서 시작되었다. 1980년대 이후 선진자본주의 국가를 중심으로 한계에 도달한 포드주의 축적체계가 포스트 포드주의로 급속히 전환되면서 사회적 양극화가 자본의 유연화 및 세계화 전략과 맞물리는 현상으로 인식되었기 때문이다. 이런 점에서 최근 전개되고 있는 한국의 사회적 양극화는 서구 선진국과 유사하다. 1997년 경제위기 이후 세계화가 급속히 진행되는 가운데 지식기반경계의 대두로 고소득 전문직이 등장하는 반면, 중산층의 몰락과 더불어 임시적 고용이 확대되고 실업이 만성화되는 등 자본의 세계화와 유연화 과정에서 나타나는 양극화 양상이 보이기 때문이다. 이와 같은 맥락에서 한국의 사회적 양극화는 이미 1990년대 초부터 진행되어 왔으며, IMF 경제위기는 단지 그러한 사회적 양극화를 급속히 진행시키는 방아쇠 역할을 하였다고 할 수 있다. 그러나 양국의 사회적 양극화는 직업구조와 임금소득의 격차만으로 설명하기 어려운 또 다른 특성을 갖는다. 왜곡된 시장구조에서 무엇보다도 부동산과 같은 자산소득의 격차가 큰 역할을 하기 때문이다. 서울은 이와 같은 한국의 사회적 양극화가 한 도시 내에서 전형적으로 전개되는 곳이라고 할 수 있다. 한국 내 어떤 도시보다도 세계화되어 있고 전문지식을 기반으로 하는 산업이 발달하고 있기 때문이다. 서울의 사회적 양극화는 공간적으로도 나타난다. 일반적으로 서울은 크게 주거지로서는 공동화되고 있는 중구 종로구 용산구 등 사대문안의 구도심지역, 강남구 서초구 송파구 등을 중심으로 한 1970년대 이후 계획적으로 계발된 이른바 강남의 신흥주택 및 신산업 지역, 영등포구 구로구 금천구 성동구 동대문구 등 제조업 중심의 구 산업 및 저소득층 주거지역 그리고 그 나머지 강북 강서 강동 등의 전형적인 주거지역 등 4개 유형으로 지역이 구분된다. 그러나 IMF 경제위기 이후에 강남구 서초구 송파구를 중심으로 하는 고소득증의 주거지와 그 나머지 주거지로 공간적 양극화가 이루어지고 있다. 사회적 양극화의 이와 같은 공간화 과정에는 자산소득의 격차를 확대하는 강남구 서초구 송파구의 높은 지가 및 아파트 가격이 중요한 역할을 하고 있다. 높은 부동산 가격이 이 지역에 대한 일종의 진입장벽을 참음으로써 고소득층에 의한 공간독점을 가능하게 하기 때문이다. 공간적 양극화를 촉진하는데는 지하철 및 문화복지시설의 집중 둥 불균형적인 공공투자와 강북에서 이전한 명문고등학교를 중심으로 형성된 8학군 등 양호한 교육환경 또한 중요한 역할을 하고 있다. 서울의 사례에서 확인할 수 있듯이, 한국에서의 사회적 양극화는 직업구조와 임금소득이라는 일반적인 요인 외에도 부동산 가격 및 소득 그리고 생활인프라의 격차를 통해 공간적 양극화물 야기하고 있다. 이러한 현상이 한국내 다른도시에서도 전개되고 있는지, 공간적 양극화로 인한 도시문제는 무엇이고 대처방안은 무엇인지 등에 대해서 후속연구가 요구된다.
