Population Grids

SDD is producing population grids for all Pacific Island Countries and Territories (PICTs) as an alternative to population statistics represented by administrative areas. Population grids represent data using square "cells". SDD is producing them at 100m x 100m (1 hectare).

Population grids are powerful tools for studying interrelationships between human activities and the environement. They are particularly useful for analysing phenomena, and their causes, which are independant of administrative boundaries such as flooding, disease outbreaks (I.e COVID relief/planning) etc

The population grids being generated for Pacific Island Countries and Territories by SDD are modelled using most recent census data projected where possible to the current year.

The images below show a sample city for each country.
