At the beginning of the 1970s, the Commission set up the “Nomenclature of Statistical Territorial Units” (NUTS) as a single, coherent system for dividing up the European Union's territory in order to produce regional statistics for the Community. Since in Italy the LAU level 1 has not yet been defined, a committee established by National Statistical Institute (ISTAT) is studying a possible delimitation. This work is set in this background, reporting only one of several diverse hypothesis developed within the committee. A set of common principles for LAU1 have been defined, deriving them from the NUTS Regulation. Consequently, likewise to NUTS, territorial units specific to certain fields of activity have been excluded, while this branch of still running experiments aims to define units of a full general nature. The expected result is the identification of a number of “settlements systems”, where the underlying law is some kind of general relationship existing between communes. So, it has been adopted a very general model of aggregation, applied to municipalities. The model considers two kinds of constraints for the aggregation: i) a hierarchical ranking of settlements, and ii) the relations between settlements, in the geographical space domain. With these constraints, an aggregative algorithm is defined, whose meaning will result by the specific variables that are used: i) to establish the settlements hierarchy, and ii) to evaluate the spatial distribution of settlements.
