Descripción
This paper reviews several approaches to create typologies of food (in)security conditions. There may be different objectives for the typologies, which influence the variables selected, methods and the number of groups formed. The definition of the adequate number of groups depends largely on the purpose of the exercise and should be maintained within a limited range that allows a manageable quantity of differentiated policy packages to be outlined. The paper also makes the point that the groups are formed based on selected variables, addressing the criticism that the typology places different countries in the same category. The paper then addresses a specific exercise to build a food security typology using cluster analysis as the classification methodology.
