Cook Islands Population Grid at 100-Meter Resolution for 2020

Cook_Islands_Population_Grid_2020 is a 100-meter resolution raster dataset depicting population distribution across the Cook Islands. The Pacific Community created it by allocating 2011 census population counts proportionally to a human settlement footprint derived from Facebook's High-Resolution Population Density Maps and applying a 0.23% annual growth rate to estimate 2020 population. The dataset is available in GEOTIFF, TXT, and ZIPPED JPEG formats.

Use Cases

• Visualizing population density patterns based on the 100-meter resolution raster grid.
• Estimating population counts for specific areas using the census-proportional allocation method.
• Analyzing human settlement footprints derived from satellite-based population density maps.
• Supporting infrastructure and service planning based on 2020 population estimates.

Strengths

• Provides a 100-meter resolution grid for detailed spatial analysis.
• Uses a documented method combining satellite-derived settlement footprints with official 2011 census data.
• Applies a specific annual population growth rate of 0.23% to project estimates to 2020.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying census data is from 2011, with estimates projected forward to 2020.
• Row count is unknown, which may limit suitability assessment.
