Sápmi is the name of the cultural region traditionally inhabited by the Sami people, the Lapps or Laplanders, as they are traditionally known in English. Sápmi is located in Northern Europe and includes the northern parts of Fennoscandia. The region stretches over four countries: Norway, Sweden, Finland, and Russia. Sápmi is the name in North Sami, while the Julev Sami name is Sábme and the South Sami name is Saemie. In Norwegian and Swedish the term Sameland is often used. It is frequently mistaken for being exclusively synonymous with the Swedish province of Lapland. (see Etymology).

With the fall of the Soviet Union and increasing internationalization, cross-border co-operation is becoming more important, and existing state borders less important both for the Sami indigenous population and non-Sami inhabitants—the latter constituting the majority population of the region. Russians and Norwegians are the most numerous groups, and the Sami make up only a small minority of about 5%. No political organization advocates secession, though several groups desire more territorial autonomy and/or more self-determination for the region's indigenous population.

Area is a quantity that expresses the extent of a two-dimensional surface or shape in the plane. Area can be understood as the amount of material with a given thickness that would be necessary to fashion a model of the shape, or the amount of paint necessary to cover the surface with a single coat. It is the two-dimensional analog of the length of a curve (a one-dimensional concept) or the volume of a solid (a three-dimensional concept).

The area of a shape can be measured by comparing the shape to squares of a fixed size. In the International System of Units (SI), the standard unit of area is the square metre (m²), which is the area of a square whose sides are one metre long. A shape with an area of three square metres would have the same area as three such squares. In mathematics, the unit square is defined to have area one, and the area of any other shape or surface is a dimensionless real number.

There are several well-known formulas for the areas of simple shapes such as triangles, rectangles, and circles. Using these formulas, the area of any polygon can be found by dividing the polygon into triangles. For shapes with curved boundary, calculus is usually required to compute the area. Indeed, the problem of determining the area of plane figures was a major motivation for the historical development of calculus.

The Sami people, also spelled Sámi or Saami, are the indigenous people inhabiting the Arctic area of Sápmi, which today encompasses parts of far northern Sweden, Norway, Finland, the Kola Peninsula of Russia, and the border area between south and middle Sweden and Norway. The Sámi are the only indigenous people of Scandinavia recognized under the international conventions of Indigenous peoples, and hence the northernmost indigenous people of Europe.Sami ancestral lands span an area of approximately 388,350 km² (150,000 sq. mi.), which is approximately the size of Sweden, in the Nordic countries. Their traditional languages are the Sami languages and are classified as a branch of the Uralic language family. The Sami languages are endangered.

Traditionally, the Sami have pursued a variety of livelihoods, including coastal fishing, fur trapping and sheep herding. Their best-known means of livelihood is semi-nomadic reindeer herding, with which about 10% of the Sami are connected and 2,800 actively involved on a full-time basis. For traditional, environmental, cultural and political reasons, reindeer herding is legally reserved only for Sami people in certain regions of the Nordic countries.
