A map of Norway north of the Arctic Circle. The three northernmost counties in Norway (Finnmark, Troms, and Nordland) are indicated in the map as well as the 10 selected municipalities included in the SAMINOR 2 Clinical Survey, 2012–2014. Footnotes: The 10 selected municipalities are presented using different colors according to their geographic location and listed in the upper left corner: 1) Yellow – Karasjok and Kautokeino municipalities represent the inland part of Finnmark County; 2) Blue – Tana, Nesseby, and Porsanger municipalities represent the coastline of Finnmark County; 3) Green – Kåfjord, Storfjord, and Lyngen municipalities represent the coastline of the northern part of Troms County; 4) Red – Skånland and Evenes municipalities represent the coastline of the southern part of Troms County and Nordland County. Sápmi, the traditional Sami settlement area (Norway, Sweden, Finland, Russia’s Kola Peninsula), is presented in orange color. The map of the study area is used with permission from the Centre for Sami Health Research (CSHR) at UiT The Arctic University of Norway. It was designed by Marita Melhus at CSHR, based on a raw map of Norway from the Norwegian Mapping Authority, and a map of Europe and Sápmi which has been released to the public domain at Wikipedia. The first time a version of this map was used was in the paper by Kvaloy et al.
