ABSTRACT
Level II regions vary in area between 94,100 sq. kms for Castilla-Léon in Spain and 404 sq. kms for the Bremen region of West Germany. In terms of both population size and population density there is similar variation. Belgium averages about 323 persons per sq. km. and Brussels 6080 per sq. km., whilst Ireland with 51 per sq. km. is the same as that of Auvergne. These differences need to be recognized when making comparisons between regions.
