Abstract Many asteroid classifications have been developed in the last years with the aim of understanding some of the physical and compositional properties of the asteroids' population. Two recent works are based on a statistical analysis of these asteroids for which a complete set of variables were available: the best pre- IRAS classification deals with a set of 589 asteroids described by seven colors indices and the first post- IRAS taxonomy was obtained analysing 438 asteroids with available both the seven color indeces and the IRAS albedo values. Both these works define eight asteroids types (S,C,D,A,E,B,M,G) while show some differences in the subtypes. In this paper we discuss these differences:some are intrinsic to the used clustering techniques, some depend on the authors attitude in reading the results. To interpret the real meaning, if any, of these differences we take into account the distribution of some asteroid types with the eliocentric distance.
