This EuroBroadMap working paper proposes a review of selected statistical tools and theoretical concepts that can be used for the elaboration of division of the world in regions, on the basis of matrix of flows or connexions (network). In order to be able to compare the strengths and weaknesses of each family of tools or concepts, and to benchmark their results, each family of tools and concepts has been applied to the same data set: the CHELEM (CEPII) matrix of trade between countries of the world for the periods 1994-96 and 2004-06, eventually disaggregated by type of goods (72 types). In some cases, we have also used a more detailed matrix of trade between 168*168 countries (1996-2000) that was aggregated into CHELEM units (93*93) in order to evaluate the effects of aggregation of countries on results.
