ABSTRACT
This chapter deals with the two categories of SMA's that, apart from the "national metropolises," have the clearest claim to the status of major metropolitan centers—"diversified manufacturing centers with metropolitan functions" and "regional metropolises." For both groups we have already given summary evidence of strong metropolitan functions and clearly recognizable relationships to metropolitan hinterlands. SMA's in the first group, which average somewhat larger in population size, combine the metropolitan functions with important and varied manufacturing functions; in the second group, on the whole, trade relations are found to be more highly developed, on a relative basis.
