GHS-POP ARCTIC R2025A – gridded population estimates for the Arctic region (1975-2030)

This dataset is part of GHSL-Arctic, the Arctic edition of the Global Human Settlement Layer. GHS-POP ARCTIC depicts the distribution of resident population in the Arctic region, expressed in population counts 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 reported in GHS-BUILT-V gridded building volume estimates 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.
