An analysis of the Michigan Catalog of two-dimensional stellar spectra (Houk and Cowley, 1975; Houk, 1978) shows that Am stars are less concentrated toward the galactic plane than normal A stars, which confirms earlier results carried out with less material. A gamma-value for Am stars about 200-350 pc is inferrable if it is assumed that Am stars are 0.75 m brighter than main sequence A-stars. It is shown that the concentration of Am stars appears to be related to the metallicity index (M-H), which could suggest that strong Am stars are more evolved objects than moderate Am stars. In an open cluster, more stars should become Am objects with increasing age of the cluster.
