Using an integrated propagation code that takes into account particle energy losses, nuclear photo-dissociation and deflections by Galactic and extragalactic magnetic fields, we simulate representative sky maps of ultra-high-energy cosmic rays over the entire sky, for a wide range of astrophysical scenarios, with different source density, spectrum and composition. We analyze these sky maps from the point of view of composition variations in different regions of the sky, and present a statistical analysis of the significance of such variations. In particular, we apply the study to the typical differences that might be expected between the northern and southern hemispheres.
