Global One-Eighth Degree Population Base Year and Projection Grids Based on the SSPs, v1.01 (2000–2100)
PURPOSE
To provide global urban, rural, and total population base year and projection grids based on the Shared Socioeconomic Pathways (SSPs) data at a resolution of one-eighth degree (7.5 arc-minutes) for climate, socioeconomic, environmental, and other related research.
DESCRIPTION
The Global One-Eighth Degree Population Base Year and Projection Grids Based on the Shared Socioeconomic Pathways, Revision 01, data set consists of global urban, rural, and total population data for the base year 2000, and population projections at ten-year intervals for 2010-2100 at a resolution of one-eighth degree (7.5 arc-minutes), consistent both quantitatively and qualitatively with the SSPs. Spatial demographic data are key inputs for the analysis of land use, energy use, and emissions, as well as for the assessment of climate change vulnerability, impacts, and adaptation. The SSPs are developed to support future climate and global change research and the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report (AR6).
ACCESSING THE DATA
The data may be downloaded at http://sedac.ciesin.columbia.edu/data/set/popdynamics-1-8th-pop-base-year-projection-ssp-2000-2100-rev01/data-download
DATA FORMAT
This archive for the Base Year 2000 contains GIS data in ASCII, Esri Grid, and netCDF formats.
This archive for the Projections 2010-2100 contains GIS data in ASCII, GeoTIFF, Esri Grid, and netCDF formats.
The data files are compressed zipfiles. Downloaded files need to be uncompressed in a single folder using either WinZip (Windows file compression utility) or similar application. Users should expect an increase in the size of downloaded data after decompression.
DATA VALUES
Data values are number of persons.
SPATIAL EXTENT
Global one-eighth degree (7.5 arc-minutes).
