Ostrobothnia is one of the two Finnish regions with a Swedish-speaking majority (the other being the constitutionally monolingual province of Åland); Swedish-speakers make up 51.2%.[1] The region contains both bilingual municipalities and ones that are exclusively Finnish-speaking.

Geographically, Ostrobothnia has little topographical relief, because it is mostly former seafloor brought to surface by post-glacial rebound and the accumulation of alluvial sediment. Ostrobothnia has both vast expanses of cultivated fields (lakeus) as in Southern Ostrobothnia, and the archipelago of Kvarken (Finnish: Merenkurkku). Glacial transport has deposited large quantities of glacial erratics (rocks) in the area.[2] Like elsewhere in Pohjanmaa, rivers are a prominent part of the landscape. The major rivers that discharge into the Gulf of Bothnia in Ostrobothnia are Kyrönjoki, Lapuanjoki and Ähtävänjoki.

The regional tree is the black alder (Alnus glutinosa), the regional mammal is the common elk (Alces alces alces), the regional stone is Vaasa granite and the regional song is "The march of Vaasa" (Swedish: Vasamarschen, Finnish: Vaasan marssi).

In local circles or communities, Ostrobothnia is often referred to as "Pampas". The word derives from the similarities in the flat landscape with the Pampas area in South America.



The region of Ostrobothnia is made up of 15 municipalities, of which six have city status (marked in bold), and the links are only in the majority language names.
