It is often argued that indicators of achievement or deprivation should be measured such that they display a property of "level-sensitivity", whereby a given change in the indicator acquires a greater significance the higher (lower) the level of achievement (deprivation) at which the change occurs. In this note, it is shown that a level-sensitive headcount ratio of poverty can be derived from an application of the very useful graphical device called "a deprivation profile" advanced by Anthony Shorrocks (in: Jenkins et al. (eds.) "The Distribution of Welfare and Household Production: International Perspectives", 1996).
