Persistence in poverty is often associated with "neighborhood effects". These effects create poverty traps that do not help lagging areas move forward on a path of sustained economic development. In the regions of a country can also operate this type of mechanism. This is one of the reasons why the territorial inequalities become persistent, becoming a perverse equilibrium. Colombia’s regional inequalities have remained and lately have become persistent. This is evident in the correlation that exists in the distribution of the rates of unmet basic needs (NBI) in the censuses of 1973, 1985, 1993 and 2005. There is a high correlation between these indexes of NBI when comparing censuses. What is truly surprising is that the high correlation when comparing the results of the censuses carried out 20 years ago. Using techniques of spatial Econometrics this paper provides evidence about the persistence in poverty, not just through the temporal dimension, but the spatial one or regional. One of the results of this study is that the spatial correlations between the conditions of poverty of a municipality in recent years with its surroundings in recent times, are high and significant. This can be interpreted as evidence for the existence of spatial traps, as there are municipalities that have remained poor and lagging, like their "neighborhoods", over time. The analysis of spatial clusters reveals that high poverty areas are located in the periphery of the country.
