Norway is divided into 11 counties, known as fylker. Each county has its own local government and administrative responsibilities. The counties include Oslo, Viken, Innlandet, Vestfold og Telemark, Agder, Rogaland, Vestland, Møre og Romsdal, Trøndelag, Nordland, and Troms og Finnmark. Counties in Norway vary in size, population, and geography. For example, Oslo is both a county and the capital city, while Finnmark is the largest county by area. Each county plays a vital role in the cultural and economic landscape of Norway, contributing to the country's diversity.
