Metropolitan Divisions are created when a metropolitan statistical area containing a single core with a population of at least 2.5 million is subdivided to form smaller groupings of counties or equivalent entities.  Not all metropolitan statistical areas with urbanized areas of this size will contain metropolitan divisions.  A metropolitan division consists of one or more main counties that represent an employment center or centers, plus adjacent counties associated with the main county or counties through commuting ties.  Because metropolitan divisions represent subdivisions of larger metropolitan statistical areas, it is not appropriate to rank or compare metropolitan divisions with metropolitan and micropolitan statistical areas.
