  We consider a metapopulation version of the Schelling model of segregation
over several complex networks and lattice. We show that the segregation process
is topology independent and hence it is intrinsic to the individual tolerance.
The role of the topology is to fix the places where the segregation patterns
emerge. In addition we address the question of the time evolution of the
segregation clusters, resulting from different dynamical regimes of a
coarsening process, as a function of the tolerance parameter. We show that the
underlying topology may alter the early stage of the coarsening process, once
large values of the tolerance are used, while for lower ones a different
mechanism is at work and it results to be topology independent.
