DIM SUM (Demography and Individual Migration Simulated Using a Markov chain) is a stand-alone Java program for the simulation of population demography and individual migration, while keeping track of genetic relationships. It does not rely on assumptions of the coalescent or of discrete population boundaries. It is extremely flexible, allowing the user to set the positions of borders, the reaction of an organism to a border, local and global carrying capacities, individual dispersal kernels, rates of reproduction, and strategies for sampling individuals. Spatial variables may be specified using image files (e.g., as exported from GIS software) and may vary thro
