The dynamic nature of social disadvantage: implications for hazard exposure and vulnerability in Greater Vancouver

Urbanization and re-urbanization continually alter spatial patterns of social disadvantage and hazard exposure, which in turn affect social vulnerability. The current study explores vulnerability to hazards in Greater Vancouver over a 15-year period (1986 to 2001). Results illustrate how social disadvantage is multi-dimensional and emerges from the social geography of a city. The study illustrates the speed with which both the structure and spatial patterns of social disadvantage can change in cities experiencing rapid growth or redevelopment. The study also suggests that Greater Vancouver does not display consistent patterns of minority- or income-based environmental inequity in hazard exposure, which raises questions about the role of various policies in ameliorating vulnerability to natural and technological hazards .
