City size distributions of urban clusters near the percolation transition: a global perspective — •Anselmo García Cantú Ros, Till Fluschnik, Steffen Kriewald, and Diego Rybski — Potsdam Institute for Climate Impact Research

Building on high resolution global land cover data we study the area and population size distribution of all cities above 100,000 worldwide. This task is accomplished by applying a percolation based city clustering algorithm. The latter also allows one to first identify a distance to the percolation threshold for clusters of cities and second to study how the proximity to percolation influences the characteristic exponent of city size distributions. Last, but not least, we study the allometric aspects of the area/population relation for the whole set of cities under scope.
