Niue Population Grid 2020 at 100-Meter Resolution

2020 population data for Niue, modeled as a 100-meter resolution raster. The dataset was created by proportionally allocating 2011 census population counts from enumeration areas to building footprints sourced from OpenStreetMap, then applying a 0.76% annual growth rate to project figures to 2020. It is provided by the Pacific Community.

Use Cases

• Estimate population exposure to natural hazards based on the 100-meter resolution raster grid.
• Analyze population density patterns based on building footprint locations.
• Project population changes for infrastructure planning based on the applied growth rate.
• Create thematic maps of human settlement distribution for Niue.

Strengths

• Data is modeled at a 100-meter spatial resolution.
• Population figures are projected to 2020 using a stated 0.76% annual growth rate.
• Based on building footprints from OpenStreetMap and official 2011 census data.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; field semantics must be inferred after download.
• Population estimates are derived from a model combining 2011 census data and building footprints, which may introduce error.
