Data forms the foundation for our empirical analyses and insights. We dedicate considerable effort to building high-quality datasets that we can trust, and we make our products as accessible as possible to researchers and policy makers.
PLACES
The “Private-Land Conservation Evidence System (PLACES) is a cluster-based software platform that synthesizes feature-rich parcel-level datasets for land conservation and environmental research in the United States. Learn more about its features, variable dictionary, and request access.
Open parcel-level data from prior publications is available for download on the PLACES Dataverse, e.g., on property-level flood risk in Massachusetts, and the impact of private land acquisitions and conservation easements on forest cover.

Data Practices for Hedonic Analyses
We worked extensively with U.S.-wide real estate data (including Zillow’s ZTRAX) to estimate conservation costs and to value environmental risks and amenities.
- We published a set of data practices for working with ZTRAX and similar large-scale tax assessor and transaction databases.
- We are co-editing a Joint Special Issue in Land Economics and the Journal of Housing Economics of ~20 U.S.-wide studies that use ZTRAX to examine how house prices are affected by different environmental amenities and risks.
