Wikipedia has a nice summary of the current status of the Irish language:
A comprehensive study published in 2007 on behalf of Údarás na Gaeltachta found that young people in the Gaeltacht, despite their largely favourable view of Irish, use the language less than their elders. Even in areas where the language is strongest, only 60% of young people use Irish as the main language of communication with family and neighbours, and English is preferred in other contexts. The study concluded that, on current trends, the survival of Irish as a community language in Gaeltacht areas is unlikely. A follow-up report by the same author published in 2015 concluded that Irish would die as a community language in the Gaeltacht within a decade.
However the government seems to be unhappy about it and attempts to prevent the Irish language from dying away:
The Irish government has adopted a twenty-year strategy designed to strengthen the language in all areas and greatly increase the number of habitual speakers. This includes the encouragement of Irish-speaking districts in areas where Irish has been replaced by English.
But why would the government support the Irish language if their own citizens seem to be unwilling to speak it? Are there any economical benefits for Ireland to be a bilingual country rather than completely switching to English?
