Growth of small and intermediate cities in Korea, 1975-1980

"This paper examines the urban growth of 33 small and intermediate Korean cities during 1975-1980 from the ecological perspective. Using the multiple regression analysis, population growth of a city is measured by variables such as industrial structure, distance from a metropolitan city, and educational level of residents in a corresponding city. At the present development stage in Korea, those cities whose industrial structure is more specialized in the transformative sector rather than other sectors have grown more rapidly. The closeness to a metropolitan city and the educational level of residents for each city strongly influence urban growth of small cities."     

A Perception Survey for the Evaluation of Urban Quality of Life in Kocaeli and a Comparison of the Life Satisfaction with the European Cities

Studies on urban quality of life (QoL) have been attracting lots of attention from various countries due to the deterioration of urban environment and decrease of the urban QoL. These studies that have been supported by international organizations such as United Nations, World Bank, OECD, European Commission and EUROSTAT (European Statistics) involve comparative assessment of life satisfaction in the European cities and comparing cities facilitate the exchange of experiment and improve the quality of local policies. The main objective of this study is to measure the local perceptions of QoL in Kocaeli, which is one of the important industrial cities of Turkey and compare the life satisfaction with the European cities. Generally, two different types of indicators have been used: objective and subjective indicators. The objective indicators cover five fields: socio-economic aspects, participation in civic life, education and training, environment and culture, and leisure. The subjective indicators are mainly for valuation of QoL perceptions in a city. In this research, a perception survey will be carried out to measure the local perceptions of QoL in Kocaeli. This survey will present on issues for which the residents in the Kocaeli had widely diverging opinions: employment opportunities, housing costs, safety, cleanliness of city, public transport, air quality and overall satisfaction with the QoL of their city. Thus, the study will become a major reference for local officials to improve QoL in Kocaeli and contribute to researches on QoL in cities.     

从“城乡二元结构”到“城市二元结构”及其影响

在我国工业化和城市化快速发展过程中,传统体制下形成的以户籍制度为核心的“城乡二元结构”不仅没有消除,反而逐步向城市蔓延,伴随着农村劳动力进城就业,在城市中形成了规模庞大的农民工阶层,他们与城市居民共同构成了“城市二元结构”。“城市二元结构”的日益强化,将导致严重的城市贫困问题,加大城市管理的难度,并造成城市化进程的不稳定。为此,应从城市和农村两个维度加以考虑,积极推动土地制度改革,加强城乡统一社会保障体系建设,加强农村基础教育和职业培训,建立以社会保障制度为核心的征地补偿机制,逐步消除“城市二元结构”。     

Population Trends as a Counterweight to Central City Decline, 1950–2000

The share of metropolitan residents living in central cities declined dramatically from 1950 to 2000. We argue that cities would have lost even further ground if not for demographic trends such as renewed immigration, delayed childbearing, and a decline in the share of households headed by veterans. We provide causal estimates of the effect of children on residential location using the birth of twins. The effect of veteran status is identified from a discontinuity in the probability of military service during and after the mass mobilization for World War II. Our results suggest that these changes in demographic composition were strong enough to bolster city population but not to fully counteract socioeconomic factors favoring suburban growth.     

Quality of life and city size: An exploratory study of Nigeria

This paper examines the variations in the quality of life at the relatively neglected inter-urban scale in a developing nation. Based on a sample survey of 3800 heads of households in Nigerian cities ranked into three categories: large, medium and small, the study found that level-of-living is related to city size, with the residents of large cities having a higher quality of life than those in the medium and small cities.     

Mixed motivations for migration in the urban prairies: A comparative approach

Two Canadian Prairie cities, with populations of about 600 000 each, have experienced dramatically different growth patterns in the last twenty years because of quite different economic bases. Edmonton has been a fast growth city based on the gas and oil boom. Winnipeg has experienced very slow growth with a very diversified economy. Through the vehicles of the Edmonton and Winnipeg Area Studies, an analysis of migration to the two cities is possible. It is a study of mixed motivation. Not only are single motives rarely expressed by respondents, but the relative strength of economic and family motives in particular is somewhat unexpected in the two cities. Finally, while return migration accounts for 50 percent of migrants to the slow growth city, it is not as detached from economic motives as appears to be the case in other Canadian research on return migration.Revised version of a paper presented at the Canadian Population Society Meeting, Hamilton, Ontario, June, 1987     

Urban Growth and Housing Quality in Iran

Rapid urban population growth and the lack of effective policies in order to desired population settlement, has encountered Iran’s major cities with multiple social, economic and environment problems. Physical expansion of cities in order to settlement the increasing population, causes the formation of new textures surrounding old urban textures. In the new textures, urban housing is formed with the modern approach and least logical connection with common practice in the old textures. Therefore, the main objective of this paper is to evaluate the housing quality and identify strengths and weaknesses in old and new urban textures to improve the quality of urban housing in Iran. Household survey were conducted to collect the needed data in the old and new textures in Khorramabad city. Results showed that the satisfaction level of housing quality in new texture is far more than old ones. The highest satisfaction level in both textures are related to housing basic facilities domain. However, satisfaction level of this domain in new texture is much greater compared to the old texture. The lowest level of satisfaction is related to the quality of neighborhood domain in old texture and to the access to public services domain in the new one. Results from the factor analysis to identify the dimensions of housing quality in old and new textures illustrated that housing quality is a multidimensional concept, studying of which requires considering all dimensions and aspects.     

Assessment of neighborhood satisfaction by residents of three housing types

A highly influential but often underemphasized determinant of residential satisfaction is how residents perceive and feel about their neighborhoods. In this study, factors representing different aspects of residents' neighborhoods were identified and examined in relation to their overall assessment of their homes and neighborhoods. Relationships among neighborhood aspects and overall housing and neighborhood assessments were examined separately for residents of conventional homes, mobile homes, and apartments. Results based on all residents indicated that evaluations of neighborhood aspects were unrelated to housing satisfaction, but were moderately related to positive sentiments and satisfaction with the neighborhood. Separate analyses by housing type revealed that neighborhood perceptions of apartment residents were influential in affecting housing satisfaction. For all residents, the neighborhood's attractiveness and pleasant-friendliness were the most important determinants of neighborhood acceptance and satisfaction. The results also indicated that despite sharing similar determinant patterns of neighborhood acceptance with the other two housing type groups, the basis for mobile home residents' evaluations was considerably less related to the factors identified as influential. The findings indicated that different neighborhood factors formed the basis for differences in overall housing and neighborhood satisfaction among residents living in the three housing types. However, since the type of housing does not by itself define a neighborhood, the differences that were found need to be considered in the larger context of other components of a neighborhood like economic and community characteristics typically associated with a specific structure type.

International Migration and City Growth in the Global South: An Analysis of IPUMS Data for Seven Countries, 1992–2013

Evidence on the demographic components of city growth in the global South is scarce, and the role played by international migration is neglected. We analyze the importance of recent international migration in cities, compare it with that of internal movements, and evaluate the growth contribution across national contexts and the urban hierarchy. Combining individual-level census data and geographic master files of metropolitan areas with indirect demographic estimation techniques, we cover 377 cities in seven countries. It is found that, in almost one third of cities, population change and replacement has been mainly determined by migration. The international component was larger than the internal one in more than half of cities. Whereas internal migration tends to decrease with rising city size, international movements tend to increase. Positive net international migration substitutes for the net losses from domestic movements in large cities, but complements the gains in intermediate-sized cities.

Satisfied Residents in Different Types of Local Areas: Measuring What’s Most Important

In efforts to enhance subjective urban quality of life (QOL), most empirical research focuses on measuring satisfaction. However, other research suggests most residents are satisfied with where they live because they choose local areas which satisfy them on attributes important to them, within the constraints they face. Thus residents choosing very different local areas tend to have similar satisfaction levels. Rather than focusing on residential satisfaction in local areas, it may be useful to focus on residential preferences to both characterize and improve subjective urban QOL in local areas. This study compares satisfaction and preference measures in four broad types of urban environment in South East Queensland, Australia. As expected, the results showed similar levels of satisfaction across these urban environments (spanning inner city, suburban, outer suburban, and coastal areas) with regard to three broad attributes (access to services and facilities, the natural environment, and the social environment). In contrast, the importance of these attributes for residents varied between these urban environments. Thus residential preferences may characterize subjective urban QOL in different urban environments better than residential satisfaction. Moreover, residential preferences provide additional guidance for maintaining and enhancing subjective urban quality of life in local areas. This paper argues for a renewed focus on importance measures in addition to the existing focus on satisfaction measures in subjective urban QOL research.

Urban growth in Korea, 1970-1980: an application of the human ecological perspective

This study supports the ecological perspective proposed by Duncan (population, environment, organization, and technology) explaining urban population growth. Data were obtained from the 1970 and 1980 Korean Population Census and Korean Municipal Yearbook on cities with a minimum size of 20,000-50,000 people (108 cities and towns). Urban growth is most strongly influenced by indigenous labor surplus and the population potential of the city to be in contact with another city. Nine multiple regression variables explained just under 66% of the variance in urban growth. Net migration was influential among those aged 15-24 years. The extent of differentiation of industry affected net migration only among those aged 15-24 years and those aged 35-44 years. Population redistribution was more affected directly by changes in industrial organization, and migration was affected indirectly by environmental and technological effects on organization. Urban growth through migration of older age groups was affected by government expenditure on public works. Urban growth was not much affected by transportation/communication concentration, manufacturing concentration, urban labor surplus, population size, and site. Urban growth was viewed as the interaction between the unemployment rate and the urban wage, following Todaro's equilibrium models. In Korea, larger cities only grew faster during the 1960s. By the 1970s, upper middle-sized cities grew faster. Location was not a significant factor in explaining urban growth, but growth was rapid along a corridor within 100 km from Seoul and 50 km from Pusan, the second largest city in Korea. Caution was urged in interpreting Korea's ecological urban growth patterns as indicative of developing countries.     

Human Empowerment and Trust in Strangers: The Multilevel Evidence

This study aimed to develop a social cohesion index for understanding the social relation between residents in high-rise group housing complexes through a self-reported questionnaire. As a background of the study, literature on social cohesion and related literature on residents’ social relation in high-rise housing were reviewed. Later, we selected different high-rise group housings of Kolkata, a city in the eastern region of India. We conducted few focus group surveys involving the residents of those high-rises and also conducted expert opinion surveys to identify a context-specific list of statements for evaluating residential social cohesion. Finally, based on the responses of interviews from 652 residents of the identified high-rise housings from the same city, followed by confirmatory factor analyses, three factors of residential social cohesion were identified with adequate reliability and validity. This index holds huge potential to explore residential social relation in high-rise housing and carry out empirical studies, across various disciplines, in other cities in the country and outside the country of similar socio-economic and cultural context.     

A further look at catholic fertility

The purpose of this paper is to determine the extent to which suburbanization has influenced the traditional fertility differences observed between Catholics and Protestants. It is hypothesized that suburbanization has served to decrease religious differences in fertility, since in the more advanced stages of urbanism, that is, suburbanization, the Catholic population is likely to adopt the fertility patterns of the larger and more secularized society. Attention is focused on two objectives: (1) to examine selected aspects of fertility for Catholic8 and Protestants living in metropolitan areas and (2) to analyze religious differentials in fertility among residents in different parts of the metropolitan community.The data, consisting of a sample of households in six metropolitan areas in three population size classes, supported the general findings pertaining to religious differences in fertility that have been reported in the literature. Catholics had larger families, shorter average spacing between children, and longer fertility spans when compared to Protestants, even when a number of control variables were employed. Examining fertility differences between Catholics and Protestants in central city and suburban segments of large and small metropolitan areas, we found that the data indicated that marked Catholic-Protestant differences are still found in central cities. However, fertility differences between the two religious groups tended largely to disappear among suburban residents. The convergence in the fertility patterns of suburbanites is due to combined effects of higher fertility among Protestant suburban residents when compared to central city Protestants and the tendency of suburban Catholics to have fewer children than those who live in the city. The net result is convergence in suburban fertility.     

Sexual risk-taking in the slums of Nairobi,Kenya, 1993-8

Relatively less attention has been paid to reproductive health problems facing deprived urban residents than to those facing rural residents in the sub-Saharan Africa. This is probably because the majority of Africans live in rural areas, where they are presumed to have poorer medical, educational, and other social services. Yet, the unprecedented rate of urbanization and the accompanying disproportionate growth in the proportion of poor city residents pose new challenges for health care in the region. This study examines differences in sexual behaviour between slum residents and non-slum residents in Nairobi city. The results show that slum residents start sexual intercourse at earlier ages, have more sexual partners, and are less likely than other city residents to know of or adopt preventive measures against contracting HIV/AIDS. The findings highlight the need to treat slum residents as a sub-population uniquely vulnerable to reproductive health problems and to expend more resources in slum settings.     

Cities evolution tree and applications to predicting urban growth

China’s unprecedented urbanization and economic modernization have brought about significant growth and land use changes in cities and their surroundings. Traditional analyses of the relationship between urbanization and land use change have not fully incorporated important factors like city function or developmental stage. We define and apply a new visualization and analysis tool—an evolution tree—showing how an understanding of evolutionary pathways taken by growing cities contributes to visualization and forecasting of urban development and spatial expansion. We clustered 253 Chinese cities by type and developmental stage, arranging them in a “tree” structure, with types grouped as branches and leaf position along branches reflecting developmental stage. Urban growth rates are higher for business-oriented, manufacturing-oriented, and functionally comprehensive cities than for those oriented toward tourism. Extent of spatial growth is dominated by city type and developmental stage. Cities evolve along typical pathways, punctuated by occasional leap developments across functional types.

Understanding the phenomenon of population flow in general. Selecting the way to deal with it carefully. A survey of population flow in Beijing]

The rapid increase in transient population has become a common phenomenon in China's major cities in recent years, and has presented new problems for city planning, construction and management. The Beijing city government conducted a large scale survey on this problem in April, 1985. According to an earlier, incomplete survey, in 1983 the daily average transient population reached approximately 500,000-600,000. The April, 1985 survey showed the number of temporary residents in the city to be 870,000. The concentration of the flow is no longer limited to before and after the Chinese new year, or during summer months; it is now a year round event. The railroad is the chief means of transportation for this influx. The flow can be divided into 3 categories: 18% to visit friends and relatives; 45.1% to study, attend conferences, conduct business, or tour the city. Other temporary visitors include people seeking employment and sellers at farm markets. By the end of this survey a new kind of flow had emerged: Beijing's textile, rubber, and leather industries had begun to attract workers from the villages, who commute daily. Many are concerned about how this uncontrolled flow could unfavorably influence Beijing's natural growth. The survey proposed taking appropriate measures to utilize this population flow and ease the conflicts it causes. To accomplish this, the city government must determine the mechanics of the flow as well as improve city management in order to respond to the challenge. The city government's responsibility should not be limited to making policies and regulations; it should delegate management and settlement of the transient population to the appropriate departments. Emphasis should be placed on providing information through the media about room and board and transportation, improving the transportation system, incorporating the farm markets into city planning, and strengthening security and supervision.
