dc.description.abstract This thesis examines the question of socioeconomic equity in sustainable cities. Of the three pillars of sustainability, social equity is typically the least researched by scholars and the least addressed by local governments. This gap in the research and policy making is problematic, particularly, when considering how the environmental challenges of the 21st century will disproportionately affect those in lower socioeconomic strata. In order to address these gaps in knowledge and gain a fuller understanding of how sustainable cities address socioeconomic equity, a survey was sent to 135 cities across the United States. Key findings include significant relationships between sub categories and the impact of education levels, Hispanic populations, and geographic location on predicting performances.
