Legacy databases and GIS: a discussion of the issues illustrated by a case study of archaeological site data from southeast Alberta,Canada

Many institutions and agencies are currently faced with the issue of geographic information systems‐enabling legacy databases. The problems can be acute for data sets that have been compiled through many years, using different standards and levels of recording. To explore these issues further, we report on a data quality assessment undertaken in 2002 for a subset of the archaeological site database of the province of Alberta, Canada. Our work shows that positional ambiguities in the data set can be highlighted and corrected by relatively straightforward procedures. This case study also provides an indication of the amount of work effort that will be involved in validating or ‘cleaning up’ data sets so model results and analyses undertaken with them are more reliable.     

La mobilité quotidienne de banlieusards vieillissants et âgés: Déplacements, aspirations et significations de la mobilité

Les premières banlieues pavillonnaires nord-américaines sont problématiques pour le vieillissement à domicile. Malgré la dépendance à l'automobile, les banlieusards âgés aspirent à y vieillir. Plutôt que de déménager, ils adaptent leur quotidien et leurs déplacements. L'accès à la mobilité est un enjeu majeur au maintien d'une expérience résidentielle positive, notamment pour les individus en perte d'autonomie. Or, parce qu'elle est étudiée avec le concept de déplacement, la mobilité des aînés demeure mal comprise en tant qu'expérience individuelle et collective. C'est dans cette optique que les pratiques et les significations de la mobilité quotidienne de 87 banlieusards âgés de 55 à 82 ans de l'agglomération de Québec au Canada sont ici étudiées. En croisant des méthodes quantitative et qualitative ainsi que des techniques d'analyses spatiales, l'article développe une typologie de mobilité pour explorer les stratégies d'adaptation des aînés à leur environnement socio-spatial. Les résultats montrent que, sans véritablement entrer dans un processus de décision, les banlieusards choisissent implicitement de vieillir en banlieue en adaptant de manière continue leurs modes de vie. La conservation de l'indépendance et l'attachement au «mode de vie banlieusard>> sont à la source des aspirations résidentielles. Cette mobilité quotidienne en transformation risque aussi d'influencer les trajectoires résidentielles, alimentant les réflexions sur la requalification de ces milieux vieillissants.     

Functional specialization across space: a case study of the Canadian Electricity Industry, 1971–2001

This article examines the location of functions within the electricity sector in Canada from 1971 to 2001, using a centre‐periphery model. Power generation, distribution and retailing are generally carried out by multiestablishment crown corporations. Location patterns of different functions—management, scientific, production, etc.—are analyzed via the use of occupational groups. The spatial distribution of functions is found to be generally consistent with centre‐periphery relationships, with evidence of a growing functional specialization between large metropolitan and nonmetropolitan locations. However, differences emerge depending on power generation sources: fossil fuels, hydro, nuclear, solar or biomass. The choice of a power generation source has consequences for local economies.     

Residential segregation and inequality: Considering barriers to choice in Toronto

Segregation of visible minorities has persisted throughout time in Toronto. In examining these concentrations, the literature has been heavily focused on the notion that visible minorities are choosing to live in proximity to their respective ethno-racial groups and that these are spaces of aspiration rather than marginalization in Canada. This paper raises questions about the assertion of “self-segregation” by emphasizing affordability constraints on residential choices that are often rooted in discrimination in the labour market. Census data from 2016 and an adopted neighbourhood classification scheme were used to understand the spatial patterning of visible minorities in the Toronto census metropolitan area and highlight differences in the socio-economic characteristics of visible minority dominant and white dominant census tracts. The findings invite the inference that economic opportunities play a critical role in the residential choices of visible minorities and raise concerns about the quality of life in visible minority neighbourhoods. This research contributes to our understanding of how social inequalities have impacted the socio-spatial organization of the city of Toronto.     

Le Conte de deux cités1 : Analyse comparative des conflits urbains de Montréal et Valence, 1995–2010

A tale of two cities: 9 Comparative analysis of urban conflicts of Montreal and Valencia, 1995–2010 Metropolization processes at work in contemporary societies produce social and spatial change, which can raise strong opposition from a variety of urban actors, leading to acts of dissent. While such urban conflict has been examined in the past, geographical analysis of urban conflicts as sociospatial processes is more recent. Systematic quantitative research on urban conflict is virtually nonexistent in terms of comparative analysis conducted with an international perspective. Systematic comparative analysis sheds light on the existing relationship between urban conflicts and the socio‐territorial contexts in which conflicts emerge and evolve. This article presents a comparative analysis of urban conflict that occurred in a selection of boroughs in two cities characterized by different geographical realities, Valencia (Spain) and Montreal (Canada), between 1995 and 2010. Spatial autocorrelation techniques applied to a conflict database show a significant relationship between the emergence of urban conflict and the spatial distribution of some contextual variables. Indeed, for Montreal as for Valencia, the concentration of urban conflict is the greatest in the most deprived neighbourhoods. Also, regarding the management and regulation of urban conflict, results shed light on important differences between Montreal and Valencia. These differences include the outcome of urban conflicts, repertoire of action of actors involved in conflict activity, and the type of contestation faced by actors who promote the challenged urban projects.     

Is it time to start worrying more about growing regional inequalities in Canada?

Much has been written recently about the rise of within-country inequality and growing imbalances of regional fortunes in the United States and the European Union. In this paper, we apply a novel geo-visualization technique that combines local indicators of spatial association with directional statistics to a unique dataset in order to explore the spatial dimensions of regional income inequalities in Canada from 1981 to 2016. After describing a pattern of growing spatial divergence among regions, we briefly discuss the need for the federal government to explore new types of place-sensitive development policies.     

Placing the second generation: A case study of Toronto

We examine the social mobility of the second generation in the Toronto metropolitan area by analyzing whether the adult children of immigrants live in more affluent and desirable neighbourhoods than the first generation. Using 2016 census microdata, we compare the social characteristics of census tracts where immigrants and the second and third-plus (3+) generations concentrate. The index of dissimilarity indicates the degree of residential separation among generations and for five ethno-racial second-generation groups: Chinese, South Asian, Black, Southern European, and Northern and Western European. The empirical findings show that the neighbourhoods where the first generation is over-represented are less affluent than those where the second and 3+ generations concentrate, with the largest improvements in social status occurring between the first and second generations. Although they frequently live in more distant suburban neighbourhoods than the first generation, the second generation still tends to live in inner and outer suburbs more than the exurban 3+ generation. For the second generation, the degree of residential concentration varies across ethno-racial groups with persistent segregation marking the residential locations of racial minorities. The findings highlight the variegated geographies and social mobility of the second generation in Canada's largest metropolitan area.     

Are new patterns of low‐income distribution emerging in Canadian metropolitan areas?

Recent studies on urban poverty in Canadian cities suggest a growing spatial concentration of poor populations within metropolitan regions. This article assesses trends in the intra‐urban distribution of the poor population from 1986 to 2006 in eight of Canada's largest cities. We consider five well‐known dimensions of segregation, as identified by Massey and Denton (1988) , in order to examine changes in the spatial distribution of poor populations within metropolitan areas: evenness, exposure, concentration, clustering, and centralization. These indices were calculated for low‐income populations at the census tract level using data from five Canadian censuses. Although each metropolitan area has distinctive characteristics, we were able to identify some general trends. The results suggest that, in 2006 compared to 1986, low‐income populations lived in more spatially concentrated areas, which were, at the same time, socioeconomically more homogeneous and more dispersed throughout the metropolitan area. In addition, we observed that over the last twenty years areas of poverty have been located, for the most part, in neighbourhoods adjacent to downtown cores. Nevertheless, we found that poverty has mostly increased in suburban areas located outside inner‐city neighbourhoods. Growing socioeconomic homogeneity and dispersion of low income areas in metropolitan areas reveal new spatial patterns of urban poverty distribution. These findings should be cause for concern as social isolation in the most disadvantaged neighbourhoods could affect the life chances and opportunities for the residents of those areas.     

Québec et la géographie sociale en questions

Questioning Québec through social geography In the early 1960s, two revolutions were underway: the quiet revolution in Québec and the quantitative revolution in geography. Apparently unrelated, these episodes of change probably shared common underlying values associated with modernity. Since then, the transformations experienced in Québec have been interpreted in a multitude of ways, including geographical considerations. Research careers, mine included, have been shaped by this undertaking. All along, I have found that social geography, with the capacity it has to reinvent itself, has helped making sense of this turbulent environment. In the 1970s, exploring the structural dynamics of Canada's social space helped in figuring out the place occupied by Québec in this ensemble. Then, analyzing the historical relationships between cosmopolitan Montréal and provincial Québec City suggested that the oxymoron ‘quiet revolution’ stood for a central process in the cultural dynamics of Québec's social space, where new ideas arriving through Montréal are sifted and institutionalized by the state in Québec City. Nevertheless, Québec City is also capable of initiating progressive urban movements, as illustrated by the odyssey of the Rassemblement populaire de Québec, documented through participant observation. Such urban movements may affect the urban fabric but, as intense and creative social networks, they may affect even more their interacting members, as it seems to have been the case with regard to rapidly evolving gender relations during the last decades. All in all, after more than four decades, I keep the conviction that a practice of social geography that is open to various theories and methods is capable of producing liberating knowledge.
