Methodology

Estimated total number of people per grid-cell. The dataset is available to download in Geotiff and ASCII XYZ format at a resolution of 30 arc (approximately 1km at the equator). The projection is Geographic Coordinate System, WGS84. with country totals adjusted to match the corresponding official United Nations population estimates that have been prepared by the Population Division of the Department of Economic and Social Affairs of the United Nations Secretariat (2019 Revision of World Population Prospects)-based dasymetric redistribution The units are number of people per pixel. The mapping approach is Random Forest. The dataset is available to download in Geotiff format at a resolution of 3 arc (approximately 100m at the equator).. The units are number of people per pixel "NoData" values represent areas that were mapped as unsettled based on the outputs of the Built-Settlement Growth Model (BSGM) developed by Jeremiah J.Nieves et al. 2020.The mapping approach is the Random Forests developed by Stevens et al. (2015). The disaggregation was done by Maksym Bondarenko (WorldPop) and David Kerr (WorldPop), using the Random Forests population modelling R scripts (Bondarenko et al., 2020), with oversight from Alessandro Sorichetta (WorldPop).SOURCE DATA:This dataset was produced based on the 2020 population census/projection-based estimates for 2020 (information and sources of the input population data can be found here).Built-Settlement Growth Model (BSGM) outputs produced by Jeremiah J.Nieves et al. 2020.Geospatial covariates representing factors related to population distribution, were obtained from the "Global High Resolution Population Denominators Project" (OPP1134076).REFERENCES:- Stevens FR, Gaughan AE, Linard C, Tatem AJ (2015) Disaggregating Census Data for Population Mapping Using Random Forests with Remotely-Sensed and Ancillary Data.
