distinctions between eastern and western Oslo. Child migration Øidne also wrote on child migration in the Agder region, among others in the 1955 work Vest-Agder heimkunnskap. The study of this field has traditionally been severely underdeveloped in Norway, but Øidne grew up in this region and was aware of the practice, which took place between 1750 and 1910. Because of poverty, children in Southern Norway were sent to work during the summer. The migration typically took place from valleys in Vest-Agder—Kvinesdal, Lyngdalen, Audnedalen, Mandalen, Marnardal, Åseral and Sirdal as well as Lindesnes—to more affluent areas in Aust-Agder, often near the coast—Høvåg, Landvik, Arendal and Grimstad as well as Birkenes and Iveland. Many emigrated to the United States when they reached adolescence. In the late phase of his life Øidne assisted the screenwriter and film director Grete Salomonsen Hynnekleiv, who spent many years working on a screenplay, Yohan: The Child Wanderer, https://www.imdb.com/title/tt1230478/?ref_=nm_knf_i1, which she also directed. The film was released in 2010 en featured Kris Kristoffersen as the story-teller.
