Population Raster Tonga 2023

Data Input:

Settlement footprint from Tonga 2021 Population and Housing Census

Population allocated by aggregating 2021 PHC household population at pixel level by sex and by 5 years old age group to generate population grids disaggregated by age and sex.

Year Population Growth Rate calculated from Population Projections available at PDH

The human settlement footprint with population allocated has been converted into a ~100 m resolution raster.

Population projection carried out with the simplifying assumption that national rates apply evenly (without other subnational input data available, it is seen as appropriate for this exercise)
