The former jurisdiction became an "Apostolic Vicariate of Denmark" on March 15, 1892. Thereafter, the island territory became for the Catholic Church an independent unit, first as the "Apostolic Prefecture of Iceland" on June 23, 1923 and then, not many years later, on June 6, 1929, as the "Apostolic Vicariate of Iceland". It was on October 18, 1968 that this entity matured into the "Diocese of Reykjavík". Even though the Catholic population remains small, both as a percentage of the overall population and in absolute numbers, it grew from about 450 in 1950 to 5,590 in 2004, during which time the total population grew from 140,000 to 290,000.
