The majority of the population are ethnic Swedes, or people who can trace most of their ethnicity to Sweden going back at least 12 generations. The Sweden Finns are a large ethnic minority comprising approximately 50,000 along the Swedish-Finnish border, and 450,000 first and second-generation immigrated ethnic Finns, mainly living in the Mälaren Valley region. Meänkieli Finnish has official status in parts of northern Sweden near the Finnish border. In addition, Sweden's indigenous population groups include the Sami people, who have a history of practicing hunting and gathering and gradually adopting a largely semi-nomadic reindeer herding lifestyle. They have been present in Fenno-Scandinavia from at earliest 5000 years to at latest around 2650 years. Today, the Sami language holds the status of official minority language in the Norrbotten, Västerbotten and Jämtland counties.
