GUTIERREZ-PULIDO, Humberto  y  GAMA-HERNANDEZ, Viviana. Limits of the marginalization indexes by Conapo and a proposal to assess municipal marginalization in México. Pap. poblac [online]. 2010, vol.16, n.66, pp.227-257. ISSN 2448-7147.

The marginalization index (IM) developed by the National Population Council (Conapo) in the 1990's has the problems that the influence of marginalization indicators on the IM greatly varies and that the IM values are not comparable over time. These problems cause that the IM is not useful to evaluate changes in marginalization. As an alternative, Conapo developed the absolute index of marginalization (IAM). However, the IAM gives equal weight to indicators which are different on their own; and then the indicators have a very different effect on IAM values. The objective of this paper is to analyze the problems of these indexes at the municipal level; and it proposes an alternative index called marginalization index for evaluation (IME). With the proposed index it is evaluated the evolution of municipal marginalization in México between 1990 and 2005.
