The Urban Settlement Patterns of Disadvantaged Migrants

Abstract

Disadvantaged migrants to metropolitan areas are segregated by race, ethnicity, or socioeconomic status within the residential areas of central city poverty neighborhoods. Whereas black migrants are generally restricted to ghetto space, regional cultural similarities and feedback in the social communication network are important to the residential location of lower class whites. The urban settlement patterns of a sample of recent disadvantaged white migrants to Indianapolis, Indiana, vary from the clusters of migrants from Appalachia and the South to the more dispersed pattern of migrants from Indiana, Illinois, and Ohio, and other metropolitan areas. The residential location of migrants from Appalachia and the South is geographically restricted by cultural constraints, and heavy reliance upon a limited network of friends and relatives in the housing search. However, the sociocultural resources of the Midwest group and the previous urban experience of metropolitan migrants increase the range of housing opportunities in Indianapolis that are available and known to them.     

Human Capital and the Structural Integration of Polish Immigrants in Australia in the First,Second and Third Generations

The Polish diaspora is one of the largest in the world. Australia's 2011 census identifies 48 611 born in Poland and 170 000 claiming Polish ancestry. Using the census, we assess the structural (socio-economic) and spatial integration of the first (Poles who arrived in the post-World War II period as largely displaced persons and refugees), second (their children) and third (grandchildren) generations, and compare the first generation with another cohort: the skilled first-generation (‘Solidarity') immigrants who arrived in the 1980s and early 1990s. Key OECD indicators of integration—education attainment, proficiency in English, employment status and occupational progression, home ownership, naturalisation, return rates and patterns of residential distribution—are examined. Results point to their successful integration, with high levels of labour market participation, earnings, and naturalisation, levels of spatial integration as exemplified in a Melbourne case study (where the highest proportions of those of Polish birth or ancestry reside), return migration and language retention, and levels of owner-occupied housing (the ‘middle-class dream') higher than among Australians generally.     

Constraints of Housing Age and Migration on Residential Mobility

This paper investigates the role of housing age in constraining residential mobility, measured as the percent of households that have moved into their homes in the past 15 months. The leading explanation for why mobility rates differ so much among regions of the United States has been the overall level of growth. The present analysis shows that the growth effect operates through both the newness of population (migration) and the newness of housing available for occupancy by all local residents. The posited explanation for this housing age effect is that progressively older units contain increasingly settled occupants, yielding fewer opportunities for in-movers in areas with older housing. It is empirically demonstrated that households in older housing have lower likelihood of recent mobility even after controlling for age, tenure, migration status, and state location of residence. The analysis reveals the temporal interdependency of mobility, migration, person age, and housing age.     

Intraurban Residential Location Of The Elderly

Abstract

Many socio-economic analyses of senior citizens presume the aged to be concentrated in the central cities of American metropolitan centers. This presumption was examined by studying the intraurban residential location patterns of the aged in Toledo, Ohio from 1940 to 1970. The residential location patterns of the elderly in each census period were mapped and discussed. Also, their residential location pattern was compared with the distributions of the non-elderly population and the black population. Although a slight concentration of aged in the central city was noted, their distribution was closely related to the distribution of the non-elderly population. Furthermore, they are much less segregated than the black population.     

广州市过剩通勤的相关特征及其形成机制

在不改变目前城市结构的前提下, 通过模拟居民的居住与就业区位的最优组合获取理论上的最小通勤, 过剩通勤是实际通勤成本与最小通勤成本之间的差值, 它反映了城市通勤效率和潜力。利用线性规划函数, 以广州市为例, 利用2001 年和2005 年家庭调查问卷数据, 计算两年的过剩通勤分别为58.41%和44.74%, 这部分通勤是可通过优化居住与就业的区位组合而理论上可节约的。过剩通勤与家庭社会经济特征有关, 尤其与家庭收入、户籍类型、 住房产权和类型等密切相关, 家庭结构分化和收入分化是产生过剩通勤的重要原因。除受模型假设产生的误差影响外, 过剩通勤的产生还受社会经济体制改革、城市规划与建设及个人 的居住与就业偏好等因素的影响; 住房、国企和土地等相关制度的改革导致城市居住与就业空间重组、城市规划较少关注小区域范围内居住与就业的平衡、个人的择居和择业偏好的变化, 这些因素相互影响、相互作用, 共同对过剩通勤的产生和扩大产生重要影响。     

扬州市住宅价格空间分异的影响因素与驱动机制

构建包含20个评价因子、4 个影响因素和4 个预期修正因素在内的城市住宅价格空间分异影响因素评价体系,基于评价因子和预期修正,分别得出单户住宅档次与水平、小区建设档次与水平、区位与生活便利性、周边景观与环境等4 个影响因素强度的得分,并分析其空间分异格局。以2012 年扬州市1305 个小区的平均住宅单价为因变量,4 个基本影响因素得分为自变量,进行回归分析,探索所有住宅及各子市场价格分异的主要因素,并分析其驱动机制。结果表明：① 4 个影响因素强度格局明显不同,住宅自身因素的格局呈现中心低外围高的圈层式分异,而外部作用因素强度呈现中心高外围低、西高东低的扇型与圈层相结合式空间分异格局;② 扬州市总体住宅价格空间分异的核心影响因素是小区建设档次与水平,不同类型住宅子市场的价格影响因素各不相同;③ 扬州市住宅价格空间分异的主要驱动力是特定住宅类型与档次建设的区位指向、特定收入阶层的空间集聚、公共物品投资的空间差异、城市居住用地扩展与城市更新的区位指向。     

The differential geography of housing affordability in Sydney: a disaggregated approach

ABSTRACT

Despite extensive studies being devoted to housing affordability in Australia, few have investigated housing affordability at a disaggregated level. This is in spite of the fact that there are existing socio-economic and demographic disparities across different regions of a city. This study aims to fill this gap by examining housing affordability in Sydney, a city that is characterised by diverse demographic and socio-economic mix, from a sub-city perspective. Two dimensions of affordability are assessed from 1991 to 2016: entry-level and ongoing housing affordability. The study finds that entry-level housing remains extremely unaffordable in all regions of Greater Sydney, although the level of unaffordability varies across regions. Specifically, the deterioration in housing affordability is more obvious in low-income regions such as Western Sydney. In addition, the ongoing housing affordability of those who have entered the market improves considerably within 5–10 years, although there are significant variations between different regions. Importantly, residents in low-income regions such as Western Sydney take a longer period to improve their ongoing affordability. The findings of differential geography of housing affordability have some profound policy implications. Policymakers should consider the disparities across different regions by formulating a more targeted and regionally balanced housing policy.

Residential mobility trajectories and integration in Douala and Bafoussam,Cameroon

Abstract

This study examines how migrant households relocate their homes in two Cameroonian cities over the course of lifetimes or even generations. The central claim is that homeownership is the ultimate sign of integration into city life. Using qualitative and quantitative research methods (218 interviews, 30 focus groups and a household survey, sample size 686), the study argues that three key factors explain why people move: the quality of housing they can affords, the proximity to a workplace and the potential for homeownership. Three residential model trajectories are identified. The first describes a journey from being a new migrant who is a guest of family or friends in the city centre to being a married family with kids owning a home in the urban periphery. The second model continues that journey by returning back to the city centre in pursuit of more convenient, high-status home location (if finances permit). A third model describes moves to sites all over the city later in life as older individuals seek to maximize family income in the way they use multiple properties. Understanding residential mobility patterns has the potential to lead to a better public policies and more effective private investments in the housing sector.     

Housing differentiation and housing poverty in Chinese low-income urban neighborhoods under the confluence of State-market forces

ABSTRACT

Based on a large-scale household survey conducted in six large Chinese cities, this study is among the first attempts to juxtapose factors related to institution, market, and demography to examine the complex patterns and mechanisms of housing differentiation and housing poverty in low-income neighborhoods, which are conventionally conceived as homogenous substandard settlements. Results of Theil indices and multivariate regression models convey several interesting findings. First, the forces of the market and the State have projected different impacts on various aspects of housing status. Institutional factors had significant impacts on some costly and durable housing indicators such as housing tenure and housing area, while market forces have swiftly transformed the most malleable aspects of housing conditions, such as housing facilities, and will eventually replace some institutional legacies. Second, within-group housing differentiation is more palpable than between-group housing differentiation, suggesting that low-income neighborhoods in large Chinese cities are fluid and heterogeneous. Third, different institutional elements have different impacts on housing poverty. The well-functioning market remuneration system helps reduce the risk of housing poverty, yet working poor remains a severe problem. These findings can inform policies promoting social mix and housing affordability.     

Heterolocalism,Networks of Ethnicity,and Refugee Communities in the Pacific Northwest: The Portland Story*

Geographic studies of refugee issues have emerged as salient topics of inquiry in the past decade. This spatial analysis of the migration experiences and heterolocal settlement patterns of refugees in an increasingly diverse part of the Pacific Northwest focuses on a place that the Atlantic Monthly recently called the last Caucasian bastion in the United States. Perceived as a region better known for its dense forests, progressive environmental policies, and rural ambience, the Portland metropolitan area and its hinterland in the Willamette Valley now resonate with ethnic and racial diversity. This article analyzes the spatial patterns and related networks of the three largest refugee groups in the region. Findings indicate that an overlapping and interrelated set of political, social, cultural, and economic networks are the most important factors in determining refugee residential patterns.     

广州市保障房住区居住环境品质及其制度影响因素研究

为应对住房市场化改革带来的严峻的住房担负问题,中央政府推行了大规模建设保障房的政策,但政策实施成效,特别是保障房住区的居住环境品质状况,仍有待进一步探究。于2015年对广州11处保障房住区居民的问卷调查和访谈,并基于与城市工作POI核密度的分析结果匹配发现,保障房住区在空间和社会双重孤立的区位很大程度上造成了其不宜人的居住环境,难以与低收入居民的实际需求相匹配。既有的行政管理体制、政府职能部门间低效的沟通、不稳定的土地来源成为阻碍保障房供应和住区居住环境品质提升的重要制度因素。     

市场转型期中国大城市低收入社区住房分异研究

基于2007年在广州、武汉、西安3个大城市的低收入社区开展的大型入户调查数据,在社区尺度探究了中国大城市低收入社区中不同社会经济群体间的住房分异情况,并分析了在社会经济转型背景下的制度因素(如户口、邻里类型、雇主类型等)和市场因素（如社会群体、年龄、受教育程度、家庭收入、职业等）对住房产权和居住条件的影响。通过计算泰尔指数发现,大城市低收入社区中不同群体间和群体内的住房分异情况都较显著,但群体内部的差异较群体间的差异更为明显。对住房条件的多元回归分析结果表明,低收入社区不同社会群体的住房条件在不同程度上受到制度因素和市场因素的影响。制度因素对住房面积等难以在短时间内改变的住房条件的作用较市场因素更显著,而市场因素对于住房设施等较易改变的住房条件的影响要比制度因素明显。     

A basic assessment of residential plant diversity and its ecosystem services and disservices in Beijing,China

About 52% of the world's population now lives in urban areas, and 41% of urban land in developed countries is used for residential areas. The amount and quality of residential green space, an important element in urban residential infrastructure, is closely correlated to city dwellers' quality of life. The quality of green spaces is not only closely correlated to the ecosystem services they provide, but also to their disservices. In order to (i) examine how plant diversity and plant traits vary in different residential areas, (ii) determine the main socio-economic factors driving plant trait variations across different residential areas, and (iii) provide an overview on selected ecosystem services and disservices related to plant diversity, we investigated the flora and socio-economic properties of 83 residential areas in Beijing, China. We found a total of 369 plant species belonging to 99 families and 150 genera. With respect to plant traits, there were 90 annual species, 174 alien species, 169 pollen allergenic species, and 133 species with edible or pharmaceutical value. The number of perennial, alien, ornamental and edible plant species was largest in residential areas completed in the 1990s. The number of allergenic species was highest in residential areas completed prior to 1980. The Simpson, Shannon and Pielou indices for trees and shrubs were highest in areas completed in the 1990s, while those same indices for herbs were highest in residential areas completed prior to 1980. General Linear Model analyses revealed that richness increased with increasing housing price across all groups of species. Principal Component Analysis indicated that housing price and floor-area ratio are the variables that positively correlate with species richness for all groups of species.     

Strategies for improving land delivery for residential development: a case of the north-west metropolitan Melbourne

One of the factors affecting the housing supply is closely linked to the time taken to complete the land development assessment approval. Delays in completing the development process on time often results in difficulties of increasing housing supply. In parallel, housing demand continues to increase with increasing net population in Australian urban areas. This research aims to identify the current issues and challenges of releasing land for housing development in the established suburbs of Melbourne north-west area (involving six local government areas: Brimbank, Maribyrnong, Moreland, Moonee Valley, Hume and Melton). An application of multi-criteria decision making (MCDM) using the strategic residential potential assessment (SRPA) method is considered. This is designed to improve the method of land administration strategies for housing development. The analysis is set within the context of investigating land preparation processes and their impacts on land availability for housing supply. The research adopts interview techniques to gain insight into the processes of land release through the activities of town planners in the selected local council areas. The proposed SRPA methods are based on a land-use assessment approach that is underpinned by the current residential land-use schemes legislated by the Department of Transport Planning and Local Infrastructure.¹ The results of applying the proposed model reveal the associated spatial pattern of areas with potential for residential development relative to the public transport and public service locations.     

基于住房需求意愿的广州市中产阶层住房区位选择

以2014年广州市中产阶层聚居区24个街道、50个社区进行的问卷调查和深度访谈资料为数据源,从住房需求意愿与区位选择方面分析了广州中产阶层住房选择,并运用多元Logistic回归分析法对其影响因素进行研究。研究发现：1）广州市中产阶层住房区位选择表现出明显的“向中心城区”性;2）现居住现状（人均住房面积、现小区区位、现小区建成年代、现居住时间）、家庭生命周期（年龄、家庭规模、子女数量）和经济水平（家庭年总收入、个人年总收入、私家车拥有量）等因素对中产阶层住房需求意愿具有显著影响;3）家庭生命周期（年龄、家庭规模）、个体因素（教育程度、户籍地）等要素对中产阶层住房区位选择具有显著影响。4）制度因素、区位因素和个体因素共同影响着广州市中产阶层住房区位选择。     

中国城市住宅价格时空演变研究进展与展望

城市住宅价格时空演变历来是城市地理学和城市经济学关注的核心内容之一。住宅价格在空间、时间分布上具有内在规律性,探索这一规律信息及其影响机制,有助于政府制定合理的房价调控和土地利用政策。本文在总结中国城市住宅价格时空演变动力机制与模式、影响因素以及技术方法等方面研究进展的基础上,指出在研究内容与研究方法方面仍存在不足,有待深化。研究结论如下:未来中国城市住宅价格时空演变研究应立足于经济转型与制度改革的特殊背景,重视住宅价格时空演变理论框架的构建;加强宏观因素对住宅价格影响的定量研究以及探索住宅价格低值集聚的内外因素,全面考察各类因素对住宅价格的影响;强化GIS 技术对城市住宅价格时空演变特征信息的挖掘,并探索多维空间在时间序列上的动态GIS 模型,实现对住宅价格时空演变与分布的模拟分析与趋势预测;拓展城市住宅价格时空演变的普及性应用,并将研究成果与城市住宅价格监测成果形成动态互补性应用。     

Homeownership and housing consumption change in Urban China: Guangzhou under market transition

ABSTRACT

Homeownership attainment is often seen as the first step in climbing the housing ladder and the building of wealth through acquisition of housing equity. While a number of authors have examined the issue of homeownership switch in China under market transition, the present paper is probably the first study on the extent of housing improvement in conjunction with and after the attainment of homeownership. Based on a household survey conducted in 2010, the study shows that ownership attainment in Guangzhou is generally accompanied by marked housing improvements, and subsequent moves bring further but percentage-wise much smaller improvements. While institution-related factors such as nature of work unit and occupational status might continue to be important, their effects on housing improvements are likely to be felt mainly through the income variable. But hukou status remains significant. More specifically, former peasants on the urban–rural fringe with claim to landownership rights have benefited most from the market-oriented land and housing reform.     

转型期广州市城市居民住房产权分异研究

利用社会-人口统计学研究方法,以问卷调查结果为基础,从自置房和租赁房、资助房和商品房两个层面,分析住房产权分异影响因素,研究发现社会经济特征变量与组织变量对住房产权分异都有显著影响,尤其是组织变量对资助房与商品房产权分异的影响更显著.家庭社会经济特征,如户主年龄、婚姻状况、家庭规模和家庭收入对产权分异的影响基本与西方类似.国有单位和工龄长的职工,享受资助房的机会相对较多.目前的住房制度改革集中在住房的私有化和大规模的商品房开发建设上,应更加关注新形势下住房分配的不平等.     

2000-2010年广州市居住空间结构演变及机制分析

首先运用因子生态分析方法对广州市2010年的居住空间结构与居住人口特征进行分析,提取出6个主因子并划分为9类居住区,得出广州市居住空间具有明显的分异性。然后与2000年的居住空间结构进行比较,归纳出广州市居住空间演变具有历史延续性、市场及政策因素影响突出、空间拓展与城市发展同步、整体居住空间呈现“圈层+扇形”融合发展等特征。根据不同的空间层次特征,概括出四种演变模式：中心区稳定发展模式、近郊区商品房拓展模式、远郊区糅合发展模式和特定区保障房镶嵌模式。探讨了广州市居住空间结构的演变机制,包括历史发展惯性、房地产发展带动、住房保障影响、城市规划引导等四个方面。最后结合国内其他大城市相关研究推导出转型期中国大城市的居住空间结构。
