Gaelic was still spoken widely on Arran at the beginning of the 20th century. The 1901 Census reported 25–49 per cent Gaelic speakers on the eastern side of the island and 50–74 per cent on the western side of the island. By 1921 the proportion for the whole island had dropped to less than 25 per cent.
Nils Holmer quotes the
Féillire (a Gaelic
almanac) reporting 4,532 inhabitants on the island in 1931 with 605 Gaelic speakers, showing that Gaelic had declined to about 13 per cent of the population. It continued to decline until the last native speakers of Arran Gaelic died in the 1990s. Current Gaelic speakers on Arran originate from other areas in Scotland. In 2011, 2.0 per cent of Arran residents aged three and over could speak Gaelic. ==Documentation==
