Islanders speak both English and a creole language known as Norfuk, a blend of 18th-century 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 2004 an act of the Norfolk Island Assembly made it a co-official language of the island. The act is long-titled: "An Act to recognise the Norfolk Island Language (Norf'k) as an official language of Norfolk Island." The "language known as 'Norf'k'" is described as the language "that is spoken by descendants of the first free settlers of Norfolk Island who were descendants of the settlers of Pitcairn Island". The act recognises and protects use of the language but does not require it; in official use, it must be accompanied by an accurate translation into English. 32% of the total population reported speaking a language other than English in the 2011 census, and just under three-quarters of the ordinarily resident population could speak Norfuk.
