If you are looking for our old ‘Global1’ 2000-2020 datasets, then these are archived here

A description of the modelling methods used for age and sex structures can be found in Tatem et al, Pezzulo et al and this poster. Both top-down 'unconstrained' and 'constrained' versions of the datasets are available, and the differences between the two methods are outlined here. The datasets represent the outputs from a project focused on construction of consistent 100m resolution population count datasets for all countries of the World structured by male/female and 5-year age classes (plus a <1 year class). These efforts necessarily involved some shortcuts for consistency.
