In this approach, the choices are termed " capabilities " and the actual levels of achievement attained in the various dimensions are called " functionings ". Thus human development is the enhancement of the set of choices or capabilities of individuals whereas functionings are a set of " beings " and " doings " which are the results of a given choice. The concept of human development proposed by Mahbub ul Haq, in the first Human Development Report in 1990 (see UNDP (1990)), largely inspired from Sen's various works, represents a major step ahead in the concretization of this extended meaning of development and in the effort to bring people's lives to the centre of thinking and analysis. Since then, human development and human deprivation have been the object of extensive theoretical and empirical research. They have been studied from various angles: conceptual, methodological, operational and policy-making. As it is not possible to directly observe and measure human development in its broad sense or the lack of it, they are generally constructed
