We analyze the multiplicity distributions of charged particles at Tevatron (pp̄) and LHC (pp) energies in the framework of the independent pair parton interactions model. It is shown that the number of soft pair parton interactions (and therefore the density of the partonic medium) is large and increases with energy. The mean multiplicity at each parton interaction grows also with energy. This growth depends on the width of the rapidity window. Similar conclusions are obtained in the multiladder exchange model.
