SPATIAL DISTRIBUTION OF PRIMARY INDIVIDUALS

Primary individuals and the households that they head now compose a significant proportion of US households. This paper examines the regional and intraurban distribution of primary households. Macro-scale data from the 1960 and 1970 Censuses are used to examine the evolving regional patterns of primary individuals and households. Using intraurban data for the 1970's, the paper also examines the impact of recent rapid growth in the number of primary individuals on the spatial distribution of primary households within urban areas. Inferences are drawn with respect to the macro- and micro-scale distributions of primary individuals and households and the impact of continued growth of this subpopulation on urban form and population distribution.     

Calculating Intraurban Agglomeration of Economic Units with Planar and Network K-Functions: A Comparative Analysis

Abstract

According to recent research, one of the most promising strategies for intraurban job growth lies promoting localized clusters that produce goods and services which are primarily sold within a single city, metropolitan area, or urban region. However, in order to design urban policies to create or reinforce local clusters, the first challenge is to measure in a reliable way the clustering tendencies of different kinds of economic units in intraurban space. The aim is to compare the similarities and differences in results obtained from two methods designed to measure global clustering tendencies (the planar and network K-functions) in terms of characterization, scale, and intensity of intraurban localization patterns for tertiary economic units in a Latin American metropolis. It is concluded that the network K-function is a more appropriate method for measuring agglomeration patterns, scale, and intensity at the intra-urban level.     

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.     

Measuring short-term population mobility among indigenous Australians: options and implications

"Despite the fact that indigenous Australians are known to be frequently mobile over the short term, statistical information regarding this population movement is grossly deficient.... This paper examines various means by which short-term population movement can be quantified to yield aggregate indicators of demographic impact. First, census data are used to establish the rate and pattern of inter-regional, short-term displacement. This reveals regional urban centres as net recipients of temporary residents while most rural areas experience temporary absenteeism. Secondly, results from household surveys are reported stressing the importance of including visitors to households in the estimation of service populations. Thirdly, administrative data on occupancy in urban hostels are used to derive indicators of the duration of movement."     

The development and applications of geographic information systems for urban and regional planning in the developing countries

Abstract

In the past 10 years, geographic information systems (GIS) have been widely used in urban and regional planning in the developed countries in Australia, North America and Europe. However, the use of GIS in urban and regional planning in the developing countries is limited and still at an early stage of development. This paper examines the current use of GIS in urban and regional planning in the developing countries in Asia. The major hindrances in the use of GIS in the developing countries is related not so much to the technology of GIS but more to data availability, leadership, organization structure and planning practice. For GIS to be more useful to urban and regional planning in the developing countries the development of a sustainable strategy in developing GIS and staff training is needed. International assistance agencies and GIS software companies can play an active role in making GIS available and usable to the planners in the developing countries.     

Town dwellers in their networks: urban-rural mobility and household strategies in Cameroon

Abstract

Urban-rural interactions are important features of spatial dynamics in Africa that have been affected by recent economic, social and cultural transformations. The attention of academics and policy-makers has concentrated on the impact of such mobility on rural actors and economies. Our objective is to consider the point of view of urban households and to analyse how they manage to develop and use their “rural connections”. The paper is based on in-depth qualitative fieldwork conducted in Cameroon, in Douala and Bafoussam. It presents an analysis of the configurations of urban resident mobility to rural regions. By mapping mobility we show the role of linkages with rural areas in urban household strategies. We also illustrate how a major city and a fast-growing secondary one differ in their connections with rural areas. The paper addresses what is one of the recurrent questions in the literature: will urban-rural linkages change in the long-term as the trend towards urbanization intensifies. Urban-rural mobility remains crucial, contributes to creating complex and dynamic networks. Collective connections are reaffirming the importance of the village and the region of origin. Mobility is a key element for many urban households in developing their urban position and strategies.     

Fluid Households,Complex Families: The Impacts of Children's Migration as a Response to HIV/AIDS in Southern Africa*

Abstract

The fluidity of southern African families is related to a long history of internal and external migration. Currently, HIV/AIDS is having a dramatic impact on extended family structures, with the migration of individual members employed as a coping strategy. Children's migration is one aspect of this that is often distinct from that undertaken by other household members. This article is based on qualitative research conducted in Lesotho and Malawi with young migrants and the households that receive them. It examines the processes of fragmentation and re-formation of households through the movements of children that are taking place in response to HIV/AIDS, and explores the impacts these processes have on young migrants and the households they join.     

Ethnic Studies: Teaching and Research Needs

Abstract

The purpose of this paper is to identify problems in ethnic studies and to discuss several teaching approaches that we have used in an attempt to meet some of these needs. Some problems of research and teaching in the field of ethnic studies include: 1) lack of awareness of the current social meaning of ethnicity; 2) data deficiencies; 3) lack of sensitivity to problems of scale in spatial analysis; 4) the separation between teaching and research; and 5) limitations imposed by discipline-bounded viewpoints. The research-teaching approaches used in the effort to counter these problems were: 1) migration histories of students' families; 2) studies of ethnic settlement at interregional, intraregional, and intraurban scales; 3) the urban ethnic field trip; and 4) the metropolitan Detroit ethnic mapping project.     

Reply To “On Farmland Protection In Southern California”

Mounting evidence indicates that large, world-class cities have expanded their spatial markets well beyond the regional urban systems in which they are located. This has led many observers to conclude that in the contemporary economy, interdependence, interaction, and connectivity are no longer fundamental characteristics of hierarchical urban systems. Virtually all research, however, deals exclusively with the changing role of large cities, while the spatial markets of medium- and smaller-sized cities comprising an urban system have been ignored. The primary objective of this paper is to investigate whether the spatial markets of medium- and smaller-sized cities in an urban hierarchical system continue to display a systematic relationship with city size, or whether they also reveal the absence of connection, or integration, with the regional system. The analysis uses survey data collected from 480 producer service firms located in an urban hierarchy comprising 15 midwestern cities of the United States. The results indicate that the spatial market of the largest city (Chicago) extends well beyond the Midwest urban hierarchy, while the spatial markets of smaller-sized cities are more integrated within the hierarchical system.     

A MAP OF URBAN PLACES,U.S.S.R., 1970

Abstract

Figures from the 1970 Soviet Census provide an abundance of information on population changes in the U.S.S.R. Of special note is the process of urbanization and a noticeable concentration of urban growth in the hitherto largely rural zones of western Russia. A large map of urban places in 1970, designed primarily for classroom use, accompanies the text (see inside back cover). The map utilizes a special stippled-sphere technique to allow a three-dimensional effect without half-tone reproduction.     

Responding to Negative Public Attitudes towards Immigration through Analysis and Policy: regional and unemployment dimensions

ABSTRACT

This paper examines two key dimensions of the impact of immigration for Australia and related policy aspects. One is sub-national and the other is national. They are, first, the regional location aspects of immigration and, second, the aggregate unemployment implications of immigration. These are chosen so as to focus on two important issues that condition public attitudes towards immigration. In relation to the first, there is a common positive view that channelling migration towards regional areas assists regional development and reduces pressure on metropolitan areas. The paper reviews regional concepts embodied in Australian immigration policy and the ways in which visa arrangements have implemented policies geared towards the regional dispersal of immigrants. Using official data, it discusses the demographic impacts of these policies and, in particular, considers the extent to which immigrants to regional Australia remain there over the longer term. In relation to unemployment, a common concern is that immigrants take jobs from local workers. The paper examines—using statistical regression methodology—the relationship between immigration and national aggregate unemployment in Australia. It evaluates the net consequences of immigration for both existing residents and new arrivals together. The paper concludes that, with good policy design in each case, regional location encouragement can be effective for immigrants and that immigrants need not take more jobs than they create. The analysis demonstrates that mixed-methods approaches to important social science issues can be productive, and helpful also for policy. Evidence, such as that presented in this paper, offers a powerful basis from which to counter negative public and political discourses surrounding immigration in contemporary Australia.     

Some Demographic and Geographic Aspects of Community Colleges

Abstract

In an attempt to apply the tools and concepts of geography to the study of higher education in the United States, some pertinent findings of the 1970 census are summarized and the spatial distribution of certain aspects of the two-year public colleges is explored. Three ratios calculated from the 1973 listing of junior colleges and from census data are mapped: average enrollment per public two-year college, ratio of public two-year colleges to population, and percentage of the population enrolled in such colleges. The maps appear to express a regionality in community college development; the need for more regional studies is emphasized and questions raised. A major conclusion is that the very states that already have the most community colleges are the ones in which continued growth in number of colleges is most likely.     

Urbanisation and centralisation in Norway

The need for population data in regional analysis

Policies targeting regional areas have been a central part of the planning system in Norway, at least since the last war – as they have been in many countries and now even on the European level through the European Union (EU). These policies are dependent upon relevant data on different regional levels. Criteria reflecting population growth, distribution and structure, are often used in analyses, preceding concrete planning initiatives and economic redistribution measures.     

AN EXPLORATORY STUDY OF OFFICE LOCATION BEHAVIOR IN GREATER SEATTLE

lntrametropolitan office location has only received limited attention in U.S. urban studies. This paper examines the particular case of Greater Seattle with reference to the relationship between public policies for office development and empirical evidence of office location change within the metropolitan area. The City of Seattle is anxious to promote the CBD as the focus of the office economy, while adjacent King County wants to promote suburban centers in which office development will be prominent. Data on the intrametropolitan movement of offices, the reasons for location choice, and the evidence of in-migration from outside the Puget Sound region have been collected. These data suggest that office location behavior in Seattle does not mirror events in other US. cities; its office economy remains highly centralized, intraurban migration has been limited, and suburban centers must rely heavily on in-situ growth of indigenous office enterprises.     

Cities and Urban Land Use in Advanced Placement Human Geography

Abstract

This article examines key topics and concepts in the cities and urban land use section of the Advanced Placement human geography course. Among the topics discussed are definitions of urbanism, the origin and evolution of cities, functional character of contemporary cities, the built environment and social space, and responses to urban growth.     

An Approach To The Editing Of Massive Computerized Data Sources

Based on interviews with corporate executives, this paper examines several decisions to locate pulp and paper mills in British Columbia during the 1960's and early 1970's. It emphasizes locational evaluations of regions, communities, and sites interpreted as parts of wider investment decision processes and longer-run corporate strategies. Relationships between initial locational decisions and post-locational assessments and adjustments are also identified.     

Rediscovering the anatomy of urban growth: The spatio-temporal evolution of building activity in a Mediterranean city

ABSTRACT

The impact of building cycles on recent expansions of Athens was assessed under the hypothesis that non-linear paths of urban growth result from sequential phases of economic growth and decline. Changes over time in building activity were examined by considering indicators derived from a local-scale analysis of building permits issued by Greek municipalities between 1990 and 2016. Relevant socioeconomic forces shaping spatio-temporal variability in building activity were identified by analyzing contextual indicators through inferential techniques and multivariate analysis. The results showed distinctive responses of real-estate local markets to economic cycles at the local scale in Athens, allowing for identification of short-term and long-term urban dynamics characteristic of expansion and recession waves. The most sensitive indicators to economic cycles in Athens were density of new buildings, average floors per new building, density of building additions, and number of building permits per inhabitant. Infrastructure-driven development, as a result of the 2004 Olympic Games, has produced relevant alterations in short-term patterns in the construction market, resulting in spatially-complex urbanization trends. The author concludes that local-scale indicators derived from building permit data provide insights into progressively complex dynamics of urban growth, with implications for regional planning and the design of sustainable development practices.     

Unbundling property in Boston’s urban food commons

ABSTRACT

Households and community organizations are involved in the creation, use, care, and management of urban spaces, including through food practices such as planting, foraging, harvesting, weeding and pruning at the ambiguous edges of public and private property. Drawing on case studies in Boston, Massachusetts, we examine how commons are articulated through these practices, particularly in relation to multiple dimensions of property rights. Specifically, we ask how food practices can open urban spaces to negotiations around access, responsibility, care, and ownership, especially when (property) ownership is not an end-goal, but a circumstance shaping other practices. Using interviews and participant observation of individuals and organizations involved in urban food provisioning, we explore how households and community organizations are interrupting fixed notions of property ownership, by practicing urban commons. These practices and negotiations demonstrate ongoing shifts in the meanings of urban space with flexible understandings of property and ownership.     

Spatial Fix and Spatial Substitutability Practices Among Canada's Largest Office Development Firms

Among agents that reflect and shape urban space, prominent property developers are powerful players. This paper examines the spatial practices of Canada's largest office development firms. These firms constantly explore new frontiers for investment, but at the same time well-established nodes are rigorously maintained and protected. Larger urban areas are preferred locations for investment; yet among them only a few cities attract the vast majority of investment. Once an investment channel is initiated and a threshold is reached, existing assets act as magnets, attracting more investment and strengthening the allure of particular places. Within a particular place (a city or a metropolitan area) the mix of properties held by a firm is likely to change over time. Core properties are considered strategic assets and therefore are retained as long-standing investments; peripheral assets have to meet corporate requirements and are thus subject to trade and replacement. Findings confirm the key position of Toronto within the Canadian urban system but also indicate that the scale of property investment does not fully correlate with urban hierarchy. On the intraurban scale, the framework of core-periphery properties helps to explain the spatial patterns of office development and the primary role of traditional nodes.     

Jobs and the Single Parent: An Analysis of Accessibility to Employment in Toronto

Abstract

In this article, we undertake an analysis of accessibility to jobs from the perspective of single-parent household members. Individuals in this demographic segment are of interest due to the fact they often face the double burden of household and employment responsibilities. A case study of the city of Toronto in Canada, an urban area that has seen an increase in absolute and relative numbers of single-parent households in recent years, is presented. Analysis is based on the application of relative accessibility deprivation indicators (RADI), which are calculated using model-based estimates of distance traveled for various population segments, as well as employment data for the city and its surroundings. The results of the analysis indicate that there are substantial differences in the levels of accessibility to jobs between members of single-parent households, in particular females, and members of other types of households.
