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 modeled from the 2017 Census and projected to 2023. Represented in 100m x 100m cells, the grid consists of 66 datasets disaggregated by sex, major ethnicity, 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.
