This is the percentages of sami in the parishes as reported by the ministers. What they reported is “Lapps” and maybe this term has been interpreted differently by different ministers. Maybe there is not a one to one correspondance of the term. White areas denotes missing information. The areas in Värmland, Dalarna, Västmanland and Gästrikland with sami population are wellknown and studied eg by Ingvar Svanberg and discussed at https://southsaamihistory.
