We provide an analogue to the classic HLP theorem consisting inproving that a version of the result due to Schur and Ostrowski onthe class of majorization order-preserving functions also holds in ourmultidimensional setting.
We address the issue of assessing multidimensional inequality byintroducing a new ordering that compare (discrete) multidimensionaldistributions representing households that di¤er in severalcharacteristics besides income and that could have di¤erent size andweights.

For any x, y 2 @, the following two conditions are equivalent:
holds for any f : R ! R that is convex and symmetric, that is invariant under any permutation of the coordinates.

The second approach studies the properties of multidimensionalevaluative inequality statistics following a two-steps procedure(Gajdos and Weymark (2005), Kolm (1977), Maasoumi (1986, 1999),Tsui (1995, 1999)).
The third approach applies some tools of convex analysis andintroduces some new attractive analytical criteria to comparemultivariate distributions (Joe and Verducci (1993), Koshevoy (1995,1998), Koshevoy and Mosler (1996), Savaglio (2006, 2011)).

Criteria borrowed from the literature on stochastic dominance whichare consistent with some very speci…c classes of social evaluationfunctionals. (Atkinson and Bourguignon (1982, 1987), Kolm (1977),List (1999), Mosler (1991)).

In sample, weights are needed in order to correct for possible biases inthe data;
In grouped data, the available information typically consists of thefrequencies (and income means) for every group;
Theoretical works on equivalence scales has stressed the importance ofweights for distributional analysis in the case of heterogeneoushouseholds.
What about di¤erent weights of individuals?
