Population Grid Samoa 2025

Data Input: Settlement footprint from Samoa 2021 Household Listing

Population allocated proportionally using 2016 census population counts at enumeration area level.

Year Population Growth Rate calculated from Population Projections available at https://stats-staging.pacificdata.org/vis?pg=0&df[ds]=ds%3ASPC2&df[id]=DF_POP_PROJ&df[ag]=SPC&df[vs]=3.0&dq=A..._T._T&pd=2017%2C2027&to[TIME_PERIOD]=false&isAvailabilityDisabled=false&hc[Indicator]=&snb=9&tm=population%20projection

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)
