The rhetoric of "inclusive development" tends often to be lost in vague generalities, when it is not altogether absent in various processes on the ground or in state policy that claims to be inspired by its demands. This note suggests that in at least one specific and restricted area of application - the intersection of poverty, inequality and growth - it should be possible to capture some elementary aspect of inclusiveness by monitoring trends, set against targets, of the "quintile income" statistic. This statistic, which was proposed in earlier work by Kaushik Basu, is a simple and useful aid to verifying the reach of inclusiveness in a specific dimension of development, a theme that is elaborated on in this note.
