Abstract: This paper introduces a class of intermediate inequality indices, I(?, ?), that is at the same time ray-invariant and unit-consistent. These measures permit us to keep some of the good properties of Krtscha’s (1994) index while keeping the same “centrist” attitude whatever the income increase is. In doing so, we approach the intermediate inequality concept suggested by Del Río and Ruiz-Castillo (2000) and generalize it in order to extend the range of income distributions which are comparable according to the ray-invariance criterion..
