Following the leaders: Sustainability engagement and urban development trajectories

Although research on local sustainability initiatives has become increasingly common, relatively little is known about whether sustainability engagement is associated with distinct long-term patterns of change. This study examines socioeconomic and demographic change in 1,340 U.S. cities between 2009 and 2023. Results indicate that cities with the highest levels of sustainability engagement experienced significantly greater increases in median household income, home values, and rents than other municipalities, while differences in poverty reduction, educational attainment, homeownership, and demographic change were modest. Cluster analysis identified four developmental trajectories, with high sustainability-engaged cities disproportionately concentrated within a High-Growth/High-Cost trajectory characterized by strong income growth and rapid housing market appreciation, while being underrepresented within a Lagging Growth trajectory. Among the three pillars of sustainability, environmental sustainability exhibited the strongest association with developmental trajectory. In addition, baseline income inequality was independently associated with subsequent income growth and housing market appreciation after controlling for sustainability engagement and other municipal characteristics. Collectively, these findings suggest that sustainability engagement is associated with distinctive patterns of urban development but likely operates within broader structural and market contexts.
