The Sámi homeland of Finland (Saamelaisten kotiseutualue in Finnish, Sámiid ruovttuguovllu in Northern Sámi, Samernas hembygdsområde in Swedish, sometimes officially translated as Sámi Domicile Area) is the northernmost part of the Lappi (Lapland) administrative region in Finland, home of approximately half of Finland's Sámi population.
The area is defined in and protected by the Finnish constitution (17 § and 121 §) to be autonomous on issues relating to the Sámi culture and language.
An important activity organized in Finland's Sámi homeland is the election of the Sámi Parliament of Finland (Saamelaiskäräjät) every four years.
The Finnish Population Registry Center does not register ethnicity.
They do register language, based on what the parents tell at birth and later changes.
