As of 2023, Norway is divided into 11 administrative regions called 'fylker'. A reform implemented in 2020 reduced the number of regions from 19 to 11, a reform which was vividly debated and partly revised, meaning that there will be 15 regions from January 1, 2024.
In 2023, the region Viken was the most populated in Norway. The region, which contains large areas surrounding the capital Oslo, had a population of nearly 1.3 million people in 2023. Oslo had the second highest number of inhabitants with around 709,000, followed by Vestland. Meanwhile, the northern region of Nordland has the lowest number of inhabitants, counting 241,000 people. At the beginning of 2023, a total of 5.5 million people lived in Norway.
