description: |
  Grid-based count of resident or ambient population per pixel/cell.
  Distinct from administrative population tables: gridded products
  redistribute census counts onto raster cells using built-up extent,
  nightlights, road networks, or settlement footprints. Flagship
  products: GHSL POP (Copernicus, 100 m / 9 arc-sec, annual epochs),
  WorldPop (100 m, country-year), Kontur Population (H3-hex, 400 m
  equivalent), LandScan (ORNL, 1 km ambient / night). Consumed by
  exposure-analysis ops (flood, heat, conflict), demographic
  weighting in service-access analyses, and humanitarian targeting
  in conflict-zone analytics where census tables are unavailable.
