The demographic composition of electoral districts has an important influence on the identities of candidates because they affect the political opportunity structures of ethnic minorities and other marginalized groups. The 2018 municipal election in Toronto, Canada provides a unique opportunity to examine how changes to electoral districts impacted the participation of visible minority candidates. At the end of the initial nomination period, the right-wing populist provincial government of Doug Ford reduced the number of city council wards from 47 to 25, which also affected the boundaries of school board districts. Candidates and aspirants then had the opportunity to re-register in the new constituencies. This change constitutes a natural experiment that allows us to isolate the impact of district structure on the relationship between demographics and candidate ethnicity. Using logistic and Poisson regression modeling, we compare the proportion and number of Visible Minority and White candidates before and after consolidation. Contra expectations, we did not find any effect on minority candidates, but show some evidence that consolidation reduced opportunities for Whites. We trace this unexpected finding to the geographic patterns of ethnic settlement. 相似文献

The simple equation of industrialisation and urbanisation contains much truth: recent national surveys confirm that rapid coal-based industrial growth spawned massive urban development in Britain. And yet at the local level a wide diversity of growth experiences reflect a complex and overlapping nexus of growth stimuli which defy attempts at generalisation. In taking a regional perspective, this paper seeks to occupy a productive middle ground in this ongoing debate. Placing urban growth in north-west England into its real economic and geographical context, it recognises the complexities of urban growth but transcends the narrowness of the particular. In so doing, it challenges some of the certainties of industrial urbanisation, emphasising instead the importance of rural industry, urban commercial functions and inter-place linkages. Most fundamentally, it argues for a more nuanced understanding of the geography of causality. 相似文献
