Commercial functional and hierarchical stability and change, 1871‐1971, are analysed for the Toronto‐to‐London area using the Davies index. The subsequent spatial analysis showed that by 1971 ‘surging’ places, those growing faster than their long‐term mean, were concentrated near larger cities, a pattern similar to 1871 except for the 1971 concentration near Toronto. The middle years 1901‐41 were the most stable on all measures. ‘Slowing’ places occurred on the northern periphery in 1871, from Toronto to Hamilton in 1901‐41, and in the rural area west of Kitchener by 1971.
Une analyse est entreprise de l‘évolution hierarchique et fonctionnelle, 1871‐1971, pour la region entre Toronto et Londres, utilisant l'indice de Davies. L'analyse spatialle demontre qu'en 1971 les centres qui etaient entrain de s'agrandir plus rapidement que la moyenne à long terme se trouvaient concentrés près des plus grandes villes, une repartition semblable a celle de 1871 exception faite de la concentration prés de Toronto en 1971. Les periodes de 1901 à 1941 furent caractérisées par le plus grand degré de stabilité sur tous les mesures. Les centres dits ralentissants se trouverent sur la limite nord en 1871, de Toronto à Hamilton entre 1901 et 1941, et dans la zone rurale à l'ouest de Kitchener en 1971.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
