subarea
Division within region
A subarea is a smaller division within a larger area.
The term appears in planning, administration, and technical contexts where regions need systematic subdivision: The city divided the district into subareas for zoning purposes.
Any defined space can have subareas—geographic regions, organizational structures, or abstract domains of study.
