The 1901 census revealed that there were only 4,419 speakers of the Manx language remaining on the Isle of Man, all of whom were bilingual. This data highlighted the rapid decline of the language throughout the 19th century, as it was increasingly displaced by English. By 1921, twenty years after this census, Manx had ceased to function as a normal means of communication.12
