The Shared Socioeconomic Pathway (SSP) Extensions Explorer is a tool for visualizing and downloading quantitative elaborations of the Shared Socioeconomic Pathways (SSPs), which emerged in the literature since the publication of the original set (e.g., GDP, population) of SSP-related indicators. The tool hosts scenarios of indicators such as Gender Inequality Index, Governance, Rule of Law, Human Development Index, and Migration Flows.
