HSL has Kirkkonummi, Kerava, Tuusula, Sipoo from the Helsinki metropolitan area and Siuntio from outside the area, and Kirkkonummi for the waste management of HSY.

Other definitions

Sometimes the term Greater Helsinki has been used in the same sense as the Capital region, but not in the official language. The term Capital region is already established in both official and unofficial use.
The term Helsinki metropolitan area may be broader than the capital region in common parlance, but it also has a precise meaning in the official language. For example, when the term Helsinki metropolitan area is used in statistics, it includes 14 municipalities, namely Helsinki, Espoo, Kauniainen, Vantaa, Kirkkonummi, Vihti, Nurmijärvi, Tuusula, Kerava, Järvenpää, Hyvinkää, Mäntsälä, Pornainen and Sipoo.
The Helsinki sub-region, which is related to the national regional division that was abolished at the beginning of 2014, must be distinguished from the Helsinki metropolitan area. The Helsinki sub-region included some of the same municipalities as the Helsinki Metropolitan Area, with the addition of Lohja, Karkkila and Siuntio.
