Over the past fifty years, preservation policy has evolved very little, despite escalating accusations that landmarking and historic districting can inhibit affordable housing, economic development, and socioeconomic diversity. The potential to understand these dynamics and effect positive change is hindered by a lack of data resources and evidence-based research to better understand these impacts. One of the biggest barriers to preservation research has been the lack of data sets that can be used for geospatial, evidence-based, and longitudinal analyses.

This first book in the series Issues in Preservation Policy explores the ways that enhancing the collection, accuracy, and management of data can serve a critical role in identifying vulnerable neighborhoods, understanding the role of older buildings in economic vitality and community resilience, planning sustainable growth, and more. For preservation to play a dynamic role in sustainable development and social inclusion, policy must evolve beyond designation and design regulation and use evidence-based research to confront new realities in the management of urban environments and their communities.
