The FGGD estimated 2015 global population
density map is a global raster datalayer with a resolution of 2.5 arc-minutes.
Each pixel contains an estimated value for persons per square kilometre
in 2015, obtained by applying population growth trends to population counts
for the lowest subnational administrative unit for which 2000 population
data were available. The method used by FAO and CIESIN to generate this
datalayer is described in FAO, 2005, Mapping global urban and rural population
distributions, by M. Salvatore, et. al.
