GHS population grid multitemporal (1975-1990-2000-2015), R2019A

The spatial raster dataset depicts the distribution of population, expressed as the number of people per cell. Residential population estimates for target years 1975, 1990, 2000 and 2015 provided by CIESIN GPWv4.10 were disaggregated from census or administrative units to grid cells, informed by the distribution and density of built-up as mapped in the Global Human Settlement Layer (GHSL) global layer per corresponding epoch.

This dataset is an update of the product released in 2016. Major improvements are the following: use of better maps reporting built-up density (GHS-BUILT); use of more recents and detailed population estimates from GPWv4.10; better representation of settlements along coastlines; critical revision of census units declared as unpopulated; WGS-84 grids added.
