About this dataset
Facebook/Meta's 30m resolution settlement layer derived from satellite imagery and census data for population mapping.
The High Resolution Settlement Layer (HRSL) from Meta provides population estimates at 30m resolution by combining census data with high-resolution satellite imagery and computer vision. It offers one of the finest-resolution global population grids available for non-commercial use.

FAQ
How does HRSL differ from WorldPop?
HRSL uses computer vision on satellite imagery to detect individual buildings before allocating population, achieving ~30m resolution. WorldPop uses dasymetric mapping at ~100m.
Is HRSL available for all countries?
HRSL coverage is progressively expanding. Many countries in Africa, Asia, and Latin America are available. Check the CIESIN portal for current country coverage.
