Advancing Spatial Demographic Insights through GIS: Results of Fiji Population Grid for 2023 and Implications

Fiu Penjueli, Fiji Bureau of Statistics

Accurate and timely population statistics, disaggregated to the lowest geographic areas, are essential for planning health and social services, allocating resources and responding to disasters and emergencies. The Fiji Bureau of Statistics, in collaboration with SPC’s Statistics for Development Division, has developed the 2023 Fiji Population Grid—a high-resolution spatial dataset modelled from the 2017 Census and projected to 2023. Represented in 100m x 100m cells, the grid consists of 66 datasets disaggregated by sex, the country’s three major ethnicities, and 5-year age groups. This experimental GIS-based approach marks a significant step in spatial demographic analysis, offering detailed insights into population distribution, demographic shifts, and inter-ethnic dynamics across Fiji. The 2023 update reveals evolving patterns in gender and age distributions, supporting more informed policy-making and planning at national and subnational levels.
