Some Extensions of Mills's Method for Urban Population Density Gradient Estimation

This paper extends Milk's method for estimating urban population density gradients to general noncircular and asymmetrical urban forms, using Gauss-Legendre quadrature embedded in a Newton-Raphson root finding algorithm. We also examine the sensitivity of the Mills method to measurement errors in the assumptions. Several issues arising from the comparison of analytical, Mills type estimation procedures with statistical procedures are explored, particularly in light of recent work that questions the negative exponential formulation of urban density gradients. We note in particular the influence of secondary population centers as a source of estimation bias.     

Cost Efficiency,Urban Patterns and Population Density When Providing Public Infrastructure: A Stochastic Frontier Approach

Relying on stochastic frontier analysis we propose a methodology to study the technological characteristics and cost efficiency levels related to the provision of public infrastructure for basic utilities. The methodology assumes a cost minimizing behaviour on the part of public officials when planning the construction of local infrastructure, which is represented by way of a flexible translog cost function. Introducing relevant definitions of scale economies, associated with larger numbers of inhabitants and dwellings, as well as economies of density, brought about by reductions in urban dispersion, we analytically determine the optimal population densities for which average cost is minimized. We illustrate our model with the water cycle sector, including water distribution, sewage collection and cleansing of wastewater, and considering data at the municipality level for the Spanish region of Castilla y León. The obtained results indicate potential cost savings in the form of decreasing average costs, as relevant scale and density economies are present, along with large inefficiency levels. Relevant policy guidelines favouring larger and denser urban sizes are drawn, as the observed cost excess is the result of a general suboptimal urban size in terms of population density, and the negative effects of dispersed settlement patterns.     

A Structural Approach to the Form of the Population Density Function

The central objective of this paper is to explore a comprehensive structural modeling approach that extracts analytical density functions answering questions raised by recent empirical studies.     

Some Questions Relating to the Formation of Urban Population

In the absence of Soviet census data on processes of formation of urban population, the author analyzes the origins of industrial workers in four urban centers of Moscow Oblast. He finds that the extent of the labor-supply area depends on the availability of local labor, the character of the skills required, the traditional occupations and work skills of the population, and certain aspects of a planned economy, such as the compulsory assignment of graduates to specific jobs and areas.     

An Immanentist Approach to the Urban

Abstract: This paper is a critical engagement with immanentist approaches to cities. Geographers approaching the urban through an immanentist lens—primarily inspired by Gilles Deleuze's work—have called into question transcendent determination, namely the determination of material reality by an external and ontologically distinct substance. This has been an implicit assumption in approaches that reduce contemporary urban developments to “effects of globalization” or “impacts of neoliberalism”. I identify two major shortcomings within the recent immanentist critique: first, their rejection of the notion of a structure in toto, and second, their noticeable silence on Louis Althusser despite his unique contribution to the question of complex causality and his shared trajectories with and influence on Deleuze. By using illustrations from the ongoing urban renewal program in Istanbul, I speculate on the ways in which an Althusserian notion of “immanent structure” could contribute to a better understanding of cities as multiplicities.     

Reconstructing Population Density Surfaces from Areal Data: A Comparison of Tobler's Pycnophylactic Interpolation Method and Area-to-Point Kriging

We compare Tobler's pycnophylactic interpolation method with the geostatistical approach of area-to-point kriging for distributing population data collected by areal unit in 18 census tracts in Ann Arbor for 1970 to reconstruct a population density surface. In both methods, (1) the areal data are reproduced when the predicted population density is upscaled; (2) physical boundary conditions are accounted for, if they exist; and (3) inequality constraints, such as the requirement of non-negative point predictions, are satisfied. The results show that when a certain variogram model, that is, the de Wijsian model corresponding to the free-space Green's function of Laplace's equation, is used in the geostatistical approach under the same boundary condition and constraints with Tobler's approach, the predicted population density surfaces are almost identical (up to numerical errors and discretization discrepancies). The implications of these findings are twofold: (1) multiple attribute surfaces can be constructed from areal data using the geostatistical approach, depending on the particular point variogram model adopted—that variogram model need not be the one associated with Tobler's solution and (2) it is the analyst's responsibility to justify whether the smoothness criterion employed in Tobler's approach is relevant to the particular application at hand. A notable advantage of the geostatistical approach over Tobler's is that it allows reporting the uncertainty or reliability of the interpolated values, with critical implications for uncertainty propagation in spatial analysis operations.     

Population Trends in Europe's Poorest Country: Results of the Most Recent Census of Moldova

An American population geographer and specialist on demographic trends in the former Soviet republics examines the results of the first post-Soviet census of Moldova (the poorest country of Europe), conducted in 2004 and released years later. He reviews major national- and regional-level changes in population size, urban/rural distribution, and ethnicity since the last Soviet-era census in 1989 and reconciles the two sets of data. A major factor complicating the analysis is the de facto secession in 1992 of an eastern region of the country, now known as the Pridnestrovskaya Moldavskaya Republic (PMR), which prompted a brief war and subsequent uneasy ceasefire later that year. However, a population enumeration conducted in the PMR, also in 2004 (and released later), facilitates the identification of overall demographic trends in the region, which may experience the involuntary return of jobless migrant workers from Russia and the EU due to the 2008/2009 global recession.

How to Reform a Reform Coalition: Outreach, Agenda Expansion, and Brokerage in Urban School Reform

Coalitions have always played an advocacy role in policymaking, but they are increasingly regarded as a form of community capacity that can be harnessed to civic ends. As explored in this study of urban school reform in Oakland, California, this civic view of coalitions confronts a tension between the cohesiveness and the inclusiveness of coalitions. Coalitions unified around cohesive goals and beliefs are often narrowly based, which can encourage the formation of rival coalitions. By contrast, reform coalitions that build broad-based support across the community may have difficulty developing coherent reform strategies. Using a social network analysis of key stakeholders to analyze the challenges of building civic capacity in Oakland, we find that the school district's recent reform experience more closely resembles an advocacy coalition than a broad civic coalition. The article then explores strategies for developing a broad civic coalition by expanding the existing advocacy coalition. We use the network analysis to identify opportunities for brokerage across individuals, institutions, and issues.     

An Information-theoretic Analysis: An Application to Soviet-COMECON Trade Flows

This paper develops a classificatory methodology designed to assign geographic entities to groupings based upon the multivariate flow profiles displayed by the entities and a dispersion statistic designed to detect dynamic shifts in these flow profiles over time. Information statistic, provide the mathematical basis of the analysis and the changing trade profiles of the member nations of COMECON provide an illustrative case study.     

Spatial Analysis of Employment and Population Density: The Case of the Agglomeration of Dijon 1999

The aim of this paper is to analyze the intraurban spatial distributions of population and employment in the agglomeration of Dijon (regional capital of Burgundy, France). We study whether this agglomeration has followed the general tendency of job decentralization observed in most urban areas or whether it is still characterized by a monocentric pattern. To that purpose, we use a sample of 136 observations at the communal and at the IRIS (infraurban statistical area) levels with 1999 census data and the employment database SIRENE (INSEE). First, we study the spatial pattern of total employment and employment density using exploratory spatial data analysis. Apart from the CBD, few IRIS are found to be statistically significant, a result contrasting with those found using standard methods of subcenter identification with employment cut‐offs. Next, in order to examine the spatial distribution of residential population density, we estimate and compare different specifications: exponential negative, spline‐exponential, and multicentric density functions. Moreover, spatial autocorrelation, spatial heterogeneity, and outliers are controlled for by using the appropriate maximum likelihood, generalized method of moments, and Bayesian spatial econometric techniques. Our results highlight again the monocentric character of the agglomeration of Dijon.     

National and Regional Population Trends in Georgia, 1989-2002: Results from the 2002 Census

An American geographer and specialist on urbanization and population change in the countries of the former USSR summarizes major results of the first post-Soviet census of Georgia, only recently released. After describing sources of census data and methodological issues warranting attention (e.g., exclusion of most of Abkhazia and South Ossetia and movements of internally displaced persons), he reviews significant national- and regional-level developments in population size, urban and rural distribution, and ethnic affiliation in the country.

Population Trends in the Russian Federation: Reflections on the Legacy of Soviet Censorship and Distortions of Demographic Statistics

A noted demographer assesses the reliability of data in the 1989 census of the Soviet Union for 14 regions of the Russian Federation affected by distortions designed by Soviet authorities to conceal the populations of "secret towns" of the military-industrial complex. More specifically, using declassified population data available but only selectively published following the disclosure of these hidden settlements (and their populations) in 1994, he re-estimates the urban populations of these regions in 1989, and compares differences in 1989-2002 population change indicated by use of the original and adjusted 1989 data sets. Distortions of up to 10 percent of the regional populations (and as high as 13 percent for their eponymous regional capitals) are examined in light of their implications for the calculation of a variety of demographic and population-based indicators in studies of Russia comparing the late Soviet and early post-Soviet periods.

The Evaluation of Urban Public Facility Location: An Alternative to Benefit-Cost Analysis

This paper attempts to overcome some specific problems which exist with the use of benefit-cost analysis in evaluating the impact of public facilities. The concepts developed explicitly recognize the importance of the spatial distribution of impacts and the fact that tastes can differ substantially among people. By utilizing the concepts of the generalized environment and of place utility, a more general and valuable conceptual model can be developed which may be useful in preventing much current conflict over public investment decisions. The model has an explicit concern with the problem of equity and is thus only a small step in a growing field of inquiry within geography.

Site Management: An Application to Wadilmeluk (the Valley of the Kings)

‘Value has always been the reason underlying heritage conservation. It is self‐evident that no society makes an effort to conserve what it does not value.’ ¹ 1. de la Torre and Mason, Assessing the Values of Cultural Heritage, 3–4. However, assessing the value of a cultural heritage asset as a representative sample of our tangible and intangible heritage for present and future generations is a difficult concept to deal with. It is, therefore, the aim of the researchers to help the conservation decision process by attempting to make an assessment of the values attributed to the cultural heritage assets of one of the most notable heritage sites in Egypt: the Valley of the Kings in Luxor.     

A Method for the Evaluation of Metropolitan Planning: Application to the Context in Spain

The metropolitan urbanization shows evidence that planning at the regional, subregional and municipal levels with its wide range of territorial, urban and sectorial competences is now longer able to significantly influence territorial development. This has led to a greater demand for alternative approaches, methods and instruments. For this research study, the metropolitan area of Granada was used as a field laboratory to assess the capacity of metropolitan planning to have an impact on metropolitan processes and dynamics. For this purpose, a method for metropolitan planning evaluation, MPE methodology, was proposed, which involves two evaluation processes. This method first evaluated the coherence of plans of different competences and at different scales within the metropolitan context (trans-scalar evaluation); it then evaluated the interaction between methods and proposals in plans and metropolitan dynamics (interactive evaluation).
