The WorldPop project was initiated in October 2013 to combine the AfriPop, AsiaPop and AmeriPop population mapping projects. It aims to provide an open access archive of spatial demographic datasets for Central and South America, Africa and Asia to support development and health applications. The methods used are designed with full open access and operational application in mind, using transparent, fully documented and shareable methods to produce easily updatable maps with accompanying metadata.
Following the 2014 conflict in Ukraine, WorldPop prioritised construction of population datasets for the country.
The datasets were built following the random forests methodology outlined here, and document estimated population per grid cell and population per hectare for each c.100x100m grid cell for different timepoints in the 2010-2020 period. The dataset is built on Rayon level 2012 estimates produced by the State Statistics Committee of Ukraine.
These datasets do not account for subsequent population displacement in Ukraine and are not recommended for use in describing current distributions.
