However, recent surveys show changes favorable towards Jeju in prevailing language attitudes. In a National Institute of the Korean Language survey in 2005, only 9.4% of Jeju Islanders were very proud of the regional variety. When the same survey was reheld in 2015, 36.8% were very proud of the language, and Jeju Islanders had become the most likely among South Korean dialect groups to have "very positive" opinions of the regional variety. In a 2017 study of 240 Jeju Islanders, 82.8% of those sampled considered Jeju to be "nice to listen to," and 74.9% hoped that their children would learn the language. But significant generational cleavages in language attitudes were also found. For instance, only 13.8% of Jeju Islanders between twenty and forty liked Jeju much more than Standard Korean, which 49.1% of those above eighty did.
