GHS-POP ARCTIC R2025A – gridded population estimates for the Arctic region (1975-2030)
Description
These spatial raster datasets depict the distribution of population, expressed in number of persons per grid cell, in 5-year intervals from 1975 to 2030. These historical (1975-2020) and projected (2025-2030) residential population estimates are derived from CIESIN Gridded Population of the World (GPW v4.11) and were disaggregated from census or administrative units to grid cells, informed by the distribution, density, and classification of residential building volume as mapped in the Global Human Settlement Layer (GHSL) data in each epoch. GHS-POP_ARCTIC_R2025A is a subset of the GHS-POP_GLOBE_R2023A product, and has been reprojected from World Mollweide projection (ESRI:54009) to the North Pole LAEA Europe reference system (EPSG:3575) using VectorCubeWarp, a tool for volume-preserving, gridded data cube resampling using areal interpolation. The underlying GHS-POP_GLOBE_R2023A is an improved product release as compared to earlier GHS-POP releases. Major improvements include: use of residential building volume for population disaggregation by integrating non-residential building volume information (GHS-BUILT-V_NRES R2023A); use of more recent and detailed population estimates derived from GPWv4.11 integrating both UN World Population Prospects 2022 country population data and World Urbanisation Prospects 2018 data for cities; revision of GPWv4.11 population growth rates by convergence to upper administrative-level growth rates; systematic improvement of census enumeration unit boundaries representing coastlines; systematic revision of census enumeration units declared as unpopulated; spatially-explicit projections to 2030 at 100m resolution.
