The aim of this paper is to study the evolution of regional differences in Colombia from 1993 to 2005. This paper uses information at the municipal (county) level about poverty and city council´s income. It is found that Colombia´s political territory is polarized around two classes of clusters: one of low poverty and high income city councils, and other of widespread poverty and low income municipalities. The first cluster is located in the country´s interior, in the Andean region and is delimited by the country´s three main cities. The second cluster comprises the bulk of the Atlantic (North) and Pacific (West) regions, as well as the Southern and Eastern parts of Colombia. Apparently, there�s evidence pointing to some positive externalities arising from proximity to one of the main three cities or being close to the transit corridors that connect each of them.
Finally, three spatial regression models are estimated that found, rather surprisingly, that there�s been a slow process of convergence among Colombia´s municipalities in tributary income). This result may by explained mainly through a process of contagion that is taking place mainly in the neighborhood of Colombia´s top three metropolitan areas, as the gap with the more distant and poor municipalities persists.
