Global 1-km Downscaled Population Base Year and Projection Grids Based on the SSPs, v1.01 (
2000 – 2100)
This data set is a downscaled version of Global One-Eighth Degree Population Base Year and Projection Grids Based on the SSPs, v1.01 (2000 – 2100), published in Jones and O'Neill (2016). The downscaling methods were published in Gao (2017):

The spatial population projections were based on future scenarios of population growth and urbanization at country scale that were developed as part of the Shared Socioeconomic Pathways (SSPs). A short summary of the scenarios behind the SSPs is available through a Population-Environment Research Network cyberseminar expert statement by Leiwen Jiang entitled "Internal consistency of assumption and projection of demographic factors in the SSPs scenarios". Additional information is available via the International Institute for Applied Systems Analysis (IIASA) SSP Database.
