| The concept of sustainability is theoretically comprised of three distinct dimensions: environmental, economic, and social. Most public and academic discourse, however, focuses on environmental and economic sustainability to the neglect of social sustainability, which refers to a condition where an extended set of basic needs are met for all residents regardless of their race/ethnicity, age, religion, gender, socioeconomic status and/or level of ability and the highest possible level of social inclusion and participation in community life is promoted. While some scholars and policymakers have recently turned their attention to social sustainability, conceptualizing and assessing social sustainability is fraught with problems. In this dissertation, I develop a comprehensive social sustainability assessment framework that focuses on six key policy areas: housing, transportation, food, leisure and recreation, social cohesion, and identity and sense of place. I then incorporate data on Vancouver, Seattle, and Portland into the social sustainability framework in order to conduct a comparative analysis of the cities' relative degree of social sustainability. My analysis---which brings both qualitative and quantitative data to bear on 30 social sustainability criteria---indicates that Vancouver is ranked higher than Seattle and Portland in terms of social sustainability. I then adapt and use two sociological theories of policy development---institutional politics theory and power constellations theory, which tend to focus on the national or state level---to test which one better explains the differential level of social sustainability in the aforementioned cities. In short, I find that power constellations theory best explains why Vancouver has the most socially sustainable policies and programs, primarily due to the strength of organized labor and center-left political parties in the city. Overall, this dissertation contributes to research on social policy development and social sustainability and provides scholars and policymakers with a deeper understanding of the institutional and political determinants of social sustainability. |
