Community-based nongovernmental organizations have emerged as leaders in local economic development, with a growing capacity for undertaking community sustainability projects in distressed neighborhoods. Very little is known about what organizational and managerial characteristics contribute to community sustainability performance. This article seeks to address this gap in the literature. Survey data from 134 community action agencies in the U.S. were analyzed to determine which organizational and managerial factors influence the effectiveness of community-based organizations in meeting community sustainability goals. The findings from an ordinary least-square regression model suggest that community engagement, human resource capacity, county/regional government collaboration, government funding, and revenue diversification are important predictors of community sustainability performance.
