Islanders speak both English and a creole language known as Norfuk, a blend of 1700s English and Tahitian. The Norfuk language is decreasing in popularity as more tourists travel to the island and more young people leave for work and study reasons; however, there are efforts to keep it alive via dictionaries and the renaming of some tourist attractions to their Norfuk equivalents. In April 2005, it was declared a co-official language of the island.Emigration is growing as many Islanders take advantage of the close ties between Norfolk and Australia and New Zealand. The sole school on the island provides education to Australian Year 12; therefore, any student seeking to complete tertiary study must travel overseas. Additionally, the small economy of the island causes many skilled workers to emigrate as well.
