FAQ
Where does the population data come from?
Population estimates come from NASA SEDAC's Gridded Population of the World (GPWv4) dataset, which combines census data with satellite imagery at roughly 1 km resolution worldwide.
How accurate is the population estimate?
It's an estimate, not an exact count — accuracy depends on the underlying data's ~1 km grid resolution and is generally better in well-surveyed regions. Very small areas may return low sample counts.
