Spatial Population Scenarios
The projected size and spatial distribution of future population are important drivers of global change and key determinants of exposure and vulnerability to hazards. Researchers from NCAR’s IAM group and the City University of New York Institute for Demographic Research developed a new set of global, spatially explicit population scenarios that are consistent with the new Shared Socioeconomic Pathways (SSPs). The SSPs describe alternative future pathways of societal change that were developed to facilitate global change research.
The spatial population scenarios cover the period 2010-2100 in ten-year time steps at a spatial resolution of 1/8-degree. Read more about the scenarios in the Environmental Research Letters paper “Spatially explicit global population scenarios consistent with the Shared Socioeconomic Pathways,” and download the related output files below. In addition, base year data for 2000 is also available for download below.
