In the end of the 1990s, Islam passed the Roman Catholic Church and Pentecostalism to become the largest minority religion in Norway, provided Islam is seen as one group. However, as of 2013, the Roman Catholic Church regained its position as the largest minority religion in Norway due to increasing immigration from European countries and less immigration from Muslim-majority countries. In 2009, the total number of registered Muslim congregations was 126. More than 40 prayer locations exist in the city of Oslo.
