The spatial population downscaling model generates projections of spatially explicit representations of population (i.e., population grid) at 1 KM resolution specific to each subnational territory (currently U.S. states) at ten-year intervals by the end of the century. It is developed based on an improved spatial gravity model and downscales projected total populations of a subnational territory from the population projection model to its constituent grid cells.
Population grids are a vital tool for resource allocation, land-cover/land-use change modeling, and human-environment dynamics. They contribute directly to exposure and vulnerability evaluation in relation to environmental hazards.
The current dashboard allows visual investigation of the spatial distribution of rural/urban/total population consistent with the SSP2, SSP3 and SSP5 scenarios for each subnational territory.
