Its lengthy visualization allows to realise suggestive inferences. Like our development this traccionado by the judgment of value of demographic deconcentration, we are going to put emphasis in around 1440 populations that are in the rank of the 600 to the 20,000 inhabitants, as well as of the urban centers inferiors to that amount. This takes implicit not only to encourage to the voluntary migrations from the metropolitan Area of Buenos Aires and the other smaller metropolitan areas, as well as of the capitals of province; but also to maintain stable to the volumes of the smaller establishments to those than we finished mentioning, but that the 20,000 inhabitants surpass. In very heavy numbers, these last establishments serian around 120. He is interesting to emphasize taking like parameter to the railway network, still in the advanced state of deterioration that is, to verify that at least an amount of establishments or potentials exists identified establishments similar to the 1440 for the purposes of deconcentration: That is to say, we would work to the effects deconcentrators with around three thousand (3000) urban establishments. With exception of Tierra Del Fuego, is almost exceptional that are urban centers outside the railway network. It is but; there are some settled in the hope of a railway branch, that in spite of being authorized legally did not get to be elevated, for want of budget or by to have decayed the interest of the investors authorized. Despite existing several railway junctions with establishments superiors to the twenty thousand inhabitants, he is possible to verify there are that them in cities of the rank that we have chosen, and that in ours to understand have a potential to develop, mainly considering the horizon of a society that will have to mobilize itself without hydrocarbons in the future not so distant (subject on which we will return more ahead).
