Abstract: Techniques for automatically creating geographic region groups are provided. Attribute data about a plurality of regions is stored. Based on the attribute data, each region is classified as belonging to a tier of multiple tiers. A first set of region groups is generated, where each region group includes at least two regions assigned to different tiers. For each region group, group attribute data for that region group is generated. A comparison of first group attribute data of a first region group is performed with group attribute data of each other region group. Based on results of the comparison, first arrangement data that associates a second region group with the first region group is stored.
