Migratory flow between Brazil and Spain among the XIX, XX and XXI centuries.

The first question that inspired the development of this work was "what motivated the change in the migratory flow between Brazil and Spain among the XIX, XX and XXI?"
Brazil was the third destination chosen by the Spanish in volume of immigrants, behind only to Argentina and Cuba (Bassanezi, 1996), In a first moment motivated by coffee and then attracted by the industry.
Nowadays the brazilians occupy the 14th position among the countries that have most immigrants within Spain. The simple combination of these two phenomena suggests that there was a reversal of flows: in the past, the Spaniards were "repelled" from Spain because of wars and were attracted by working conditions in Brazil; nowadays, Brazilians are "expelled" also the country due to poor employment conditions and safety, among other factors, and depart for Spain, in search of better living conditions.
However, Patarra (2005) says that this reasoning is wrong. The entry and exit of people from Brazil never stopped; context, characteristics, and significance of the volume flows are totally different and can not be compared. For her, "the international migratory movements constitute the planetary territorial restructuring - which, in turn, is intrinsically related to restructuring economic-productive on a global scale." (Patarra, 2005, p.24)
