The distances between urban and suburban spaces, while small in Euclidean terms, have a rather large social reality. This paper calls attention to two reasons for this—suburban development and metropolitan fragmentation—and situates these phenomena within the context of sociological and historical thought about metropolitan areas. I test their role in linguistic variation through a case study of three Northern Cities Shift features (raised trap, fronted lot, and lowered thought) in English of the St. Louis metropolitan area. I show that these features diffused throughout the region in three different ways. Additionally, phonological conditioning of lot-fronting differs between urban and suburban speakers, and retreat from urban dialect features is led in the suburbs. These findings highlight the need to consider the geography of metropolitan areas more deeply in studies of language variation and change in metropolitan areas, as similarity across a metropolitan area should not be assumed a priori.

Using census data, this study investigates change in the residential segregation of persons age 65 years and over from younger persons in Canadian census metropolitan areas (CMAs) between 1981 and 1991. In each CMA, age-segregation is first evaluated in terms of inner city-suburban population distributions, and then according to the degree of segregation across census tracts expressed by the Index of Dissimilarity. Although the CMAs typically had moderate segregation levels in both 1981 and 1991, there were consistent trends toward (i) increasing proportions of the elderly living in suburban areas, and (ii) declining degrees of age-segregation across census tracts. It is proposed that these trends are partly attributable to the aging in place of suburban residents. Correlation and regression analyses indicate that in 1991 lower degrees of segregation were associated with CMAs which had relatively high percentages of both older dwellings and elderly population. The policy implications of the results are discussed.
