A population raster can encode people per cell, density, constrained allocation or a model for a particular epoch. Those are not interchangeable inputs to a sum over an area.

Unlock a source-based comparison of GHSL GHS-POP and WorldPop's constrained/unconstrained approaches, plus a small conservation example and a dataset-selection worksheet. It is intended for researchers choosing data and checking units before running a GIS workflow.

The public documentation was checked on 18 October 2026. This is a method-selection aid, not a certified count for any settlement, a downloaded raster bundle or a claim that one model is universally most accurate. #PopulationData #GIS
