Papers Evaluate the Accuracy of Global Population Products
Two recent papers evaluate the accuracy of global gridded population data products against reference data sets. The first paper, published in Population and Environment, conducts a pixel level evaluation of population counts across space (different levels of urbanization) and time. The second paper, published in BioRxiv (a preprint for the journal Biology), measures the accuracy of various products for Bioko Island, Equatorial Guinea. A major goal of the next phase of the POPGRID Data Collaborative is to compare and validate global products in different regions.
