Population density map (HRSL-GSHL) 2022

Population density map for 2022 at 30arcsec resolution.

The layer integrates data from the High Resolution Settlement Layer (HRSL) - META (originally Facebook), the Global Human Settlement Layer (GHSL) - JRC, and the national population count for 2018 reported on the World Population Prospects 2019.

Using the country borders (level 0) of the UN Cartographic Section 2020 (BNDA_CTY), countries with full data coverage from HRSL use it. Countries with missing or partial coverage from HRSL use GHSL. Both the original layers of HRSL and GHSL were, first, recalculated at 30arcsec resolution (~1km) through an aggregation process (sum) and, then, integrated into one single layer. Pixel counts were then recalculated for 2022 based on the country population data reported for 2022 by the World Population Prospects 2019.
