Metropolitan statistical area
In the Republic of Alduria, a metropolitan statistical area is a geographical region with a relatively high population density at its core and close economic ties throughout the area. They are not legally incorporated into one whole city or town, nor are they actual administrative divisions either. A typical metropolitan area is centered on a single large city that wields substantial influence over its surrounding conurbation.
A metropolitan statistical area is defined in Alduria by the Department of the Interior, and used by its Bureau of National Statistics and other national, state, and local government agencies for statistical purposes.
