Determining global population distribution: methods, applications and data

Abstract

Evaluating the total numbers of people at risk from infectious disease in the world requires not just tabular population data, but data that are spatially explicit and global in extent at a moderate resolution. This review describes the basic methods for constructing estimates of global population distribution with attention to recent advances in improving both spatial and temporal resolution. To evaluate the optimal resolution for the study of disease, the native resolution of the data inputs as well as that of the resulting outputs are discussed. Assumptions used to produce different population data sets are also described, with their implications for the study of infectious disease. Lastly, the application of these population data sets in studies to assess disease distribution and health impacts is reviewed. The data described in this review are distributed in the accompanying DVD.

Process by which GRUMP population surface is constructed, illustrated for southern Ghana. Panel 1 shows inputs side by side with their population counts. Panel 1A is identical to the inputs to GPW, panel 1B shows the additional urban areas used in GRUMP. In panel 2, the inputs are merged, first illustrated as an overlay of the urban footprints over the administrative polygons in panel 2A, and the final grid, in panel 2B (with administrative and urban) boundaries overlaid (density/square km).
