Spatial illustration of population density and non-uniform attack rates generated using different mobility assumptions.

(A) Log10 population density (people/km2). (B) Difference between location-specific attack rates and global attack rate for S-mobility and (C) difference between location-specific attack rates and global attack rate for I-mobility. We change color scale between plots to better illustrate the emergent patterns. A total of 4 pixels are unpopulated and so attack rates are necessarily always zero in these locations.
