Global Commons Stewardship Index: A Statistical Review of the Pilot Methodology
Jun 21, 2021
This Working Paper is a companion to the Pilot Global Commons Stewardship (GCS) Index (SDSN et al., 2020), released at the Tokyo Forum in December 2020 by the Center for Global Commons (CGC) at the University of Tokyo. The Pilot Index Report contains details about its data and construction, especially in its appendices containing country profiles and methodology, but here, we present more detailed statistical analyses of the metrics, choices, and assumptions. This Working Paper provides additional transparency about the Pilot Index and discrete guidelines for improving further iterations. In particular, we address the categorization of the metrics, describe imputations and outliers, recommend the use of geometric means for aggregation, note areas needing greater data availability, and suggest new ways of interpreting this work in the narrative of the report.
