Global Population Projection Grids Based on Shared Socioeconomic Pathways (SSPs), 2010-2100

The Global Population Projection Grids Based on Shared Socioeconomic Pathways (SSPs), 2010-2100 consists of global spatial population projections at a resolution of one-eighth degree (7.5 arc-minutes) for urban, rural, and total population, consistent both quantitatively and qualitatively, with the SSPs at ten-year intervals for 2010-2100. Spatial demographic projections 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). This data set is produced based on a clear need for plausible alternative projections of spatial distribution of the population that can represent patterns of development consistent with the SSPs.

2010-2100年共享社会经济路径（Shared Socioeconomic Pathways, SSPs）全球人口投影栅格数据集包含以1/8度（7.5弧分）为空间分辨率的城镇、乡村及总人口全球空间人口投影数据，该数据在数量与质量上均与共享社会经济路径（SSPs）框架保持一致，时间间隔为十年，覆盖2010至2100年时段。空间人口投影是土地利用、能源消费、碳排放分析，以及气候变化脆弱性、影响与适应措施评估的关键输入数据。共享社会经济路径（SSPs）旨在支撑未来气候与全球变化研究，以及政府间气候变化专门委员会（Intergovernmental Panel on Climate Change, IPCC）第六次评估报告（AR6）的相关工作。本数据集的研发源于对能够表征与共享社会经济路径（SSPs）发展模式相符的人口空间分布合理替代投影方案的明确需求。
