Abstract
This document performs profile analysis of income inequalities in Cameroon, between 1996 and 2001.It concerns origin determination and the components of inequalities in Cameroon. The study is structured around the new subgroup decomposition of the Hirschman-Herfindahl index. The economic and empirical pertinence of this indicator holds on its tridecomposition into three components: the within group's, the between group's net and the between group's transvariation. Inequalities are evaluated by grouping and lead to differents interpretations. The selected data for analysis are from the two Cameroonian Surveys to Households ECAM I and ECAM II. The dependent variable (total expenses per head), the independent variables (sex, place of residence and standard of living) and also the method (simulator H-H) have a particular interest in our work. The analyses results indicate that households present a very strong inequality of expenses on considered period. Heterogeneity is very important between groups while, homogeneity is quite considerable within the different groups. The contribution of the transvariation (or overlapping) to the total inequality revealed itself to be incontestable and varies depending on the dependent variable studied. Households directed by women are more victims of disparities. The Inequality is a characteristic of a semi-urban zone, and it is principally a phenomenon relative to poor households. This reflection calls for measures to fight, which must be focus on between groups inequality and on the subgroups of population the most underprivileged.

Abstract: (french)
Ce document fait une analyse du profil des inégalités de revenu au Cameroun entre 1996-2001. Il s'agit donc de déterminer l'origine et les composantes des inégalités au Cameroun. L'étude est structurée autour de la nouvelle décomposition par sous-groupe de l'indice d'Hirschman-Herfindahl. La pertinence économique et empirique de cet indicateur tient à sa tridécomposition en composante intragroupe, composante intergroupe nette et une composante intergroupe transvariationnelle. Les inégalités sont estimées de manière groupée et conduisent à des interprétations différentes. Les données choisies pour cette analyse, sont celles des deux Enquêtes Camerounaise Auprès des Ménages ECAM I et ECAM II. La variable dépendante (dépense totale par tête) et les variables indépendantes (sexe, milieu de résidence et niveau de vie), ainsi que la méthode (simulateur H-H) sont d'un intérêt particulier dans notre travail. Les résultats des analyses indiquent que les ménages présentent une très forte inégalité en termes de dépenses sur la période considérée. Dans l'ensemble, l'hétérogénéité est très importante entre les groupes de ménages, tandis que l'homogénéité est assez considérable à l'intérieur des différents groupes. L'apport de la transvariation à l'inégalité totale s'est révélé incontestable et varie selon la variable explicative étudiée. Les ménages dirigés par les femmes sont plus victimes des disparités. L'inégalité est une caractéristique du milieu semi urbain, et elle est principalement un phénomène lié aux ménages pauvres. Cette réflexion fait appel à des mesures de lutte qui doivent se focaliser sur l'inégalité intergroupe et se concentrer sur les sous-groupes de population les plus défavorisés.
