Is it rare for someone from Dublin, Ireland to speak Irish fluently?

I believe it will be rare since only 10% of the Irish population are still able to use Irish fluently.

Rare in Dublin. Although, I think the school system is now incorporating Gaelic into the education system. Very few people in Ireland use Gaelic daily, I think it is less than 100,000, but around 1 million can speak it fluently. I looked it up a while back for another Q. I had a coworker who spoke Gaelic, it was the language she priimarily used with her family. she was Irish, but had been living in the states a few years when I met her.

It would be hard to find people in Dublin who can speak Irish with a high degree of fluency nowadays. Irish is a compulsory subject all the way through school so everyone might know a little, but once they leave school I don’t think people might speak Irish much.

Irish? Are you talking about Gaelic?

You might enjoy this article from The Guardian, in which the writer travels around Ireland speaking only Irish Gaelic.

There are pockets in Ireland – such as Galway and Connermara – where Gaelic is spoken a lot but it would not be commonplace in Dublin.
