60 percent certain, based on the evidence available
"The vitality of Reo Ra’ivavae is undeterminable with the currently available data. The most recent census reports 524 out of 703 people over fifteen years of age in Ra’ivavae speak the language at home (Institut de la Statistique de la Polynésie française 2017), however it is unclear whether this represents people speaking a local variety of Tahitian or traditional Reo Ra’ivavae."
MORE ON VITALITY
"The Ra’ivavae population is undergoing language shift to Tahitian and there exists some degree of multilingualism on the island with French as well. While the exact degree of endangerment is unclear, the language is under threat and urgently requires significant study as there is as of yet very little documentation or description of the language... No formal language-use survey has been conducted yet, but based on the authors’ firsthand observations, the majority of children are no longer learning Reo Ra’ivavae at home... there is clear language shift ongoing in all districts."

LANGUAGE CONTEXT COMMENTS
"Reo Ra’ivavae is the autochthonous language of Ra’ivavae, however French is official on the island and is used in governmental and educational domains... Education is conducted mostly in French, with a few hours per week dedicated to Reo Ra’ivavae. Tahitian, as the lingua franca of French-occupied Polynesia, is also spoken, particularly between immigrants from other islands. For the Ra’ivavae diaspora on Tahiti, almost all are multilingual in both Tahitian and French."
