American Samoa Population Grid for 2020 Based on Census and Satellite Data

Population Raster American Samoa 2020 allocates population proportionally using 2011 census counts at the enumeration area level. The data uses a settlement footprint from Facebook's High-Resolution Population Density Maps and applies a 0.23% annual growth rate to update the population to 2020. It is provided by the Pacific Community.

Use Cases

• Estimate population exposure to natural hazards based on the settlement footprint.
• Model service accessibility and infrastructure planning using the population grid.
• Update demographic analyses for 2020 based on the applied growth rate.
• Integrate with other geospatial layers for environmental or social research.

Strengths

• Uses a high-resolution settlement footprint from Facebook's population density maps.
• Applies a documented annual population growth rate of 0.23% to update census data to 2020.
• Data is provided under a permissive CC-BY-4.0 license.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying census population counts are from 2011, which may not reflect recent demographic shifts.
• Row count is unknown, which may limit suitability assessment.
