The FD (Fully Differentiated) File includes separate records for every urban ward (qu) as well as every county-level unit. The MC (Municipality-Compatible) File attempts to compensate for arbitrary differences in the administrative geography of municipalities by merging certain tightly drawn municipalities with their surrounding counties to achieve greater comparability. These mergers also ensure that, in the course of regional analysis, the immediate hinterland of a city ends up in the same zones and classes as the city itself. The RS (Regional Systems) datafile incorporates subdivisions of counties that our analysis has shown to be divided between regional systems. CITAS is not providing digital basemaps of these coverages at this time.
