FAQ

What resolution is WorldPop population data?

WorldPop provides population grids at approximately 100m (3 arc-seconds) resolution, making it one of the highest-resolution global population datasets available.

How does WorldPop differ from LandScan?

WorldPop offers higher spatial resolution (~100m) with explicit census integration, while LandScan provides a 1km ambient population distribution focused on where people are during the day rather than where they live.
