Eastern Norway consist of the counties Innlandet, Oslo, Vestfold og Telemark, and Viken. Together, these counties make up 30% of the land area and, with about 2.7 million inhabitants, approximately half the population of Norway. Eastern Norway is the national center of gravity in terms of both population and commerce. During the last decades, the population growth has been slightly higher than the rest of the country. The growth has been particularly high in the Oslo metropolitan area, the dominating center of the region.
Furthermore, Eastern Norway is also the Norwegian hub for road, rail, air and sea transport. Most of the urban settlements are located within the triangle between Lillehammer, Skien and Halden. Due to the setup of the railway system of Eastern Norway, the area is sometimes referred to as the «InterCity Triangle».
From an international point of view, Eastern Norway is a small region, located on the outskirts of Europe. Although the region enjoys high levels of development, it has significant drawbacks when faced with the strong competition of global markets. Infrastructure development is key for the competitiveness of a region, and the infrastructure of Eastern Norway is not satisfactory, neither from a national nor a European perspective.
