Except for an exceptional period between 2012 and 2015, Ireland has had net inflow of migrants for years. Even if you focus purely on Irish people emigrating, the numbers are tiny - about 30k a year from a population of nearly 5 million - mostly from outside Dublin. So there's no trace of many people migrating for economic reasons in the statistics. I will admit that I've more or less given up arguing with my friends who live in Dublin about housing - some sort of mass hysteria has taken hold and normally well-informed people are convinced that Dublin "has the worst property crisis in the world" when all statistics comparing Dublin with other European cities show that buying or renting property there is about average or better in terms of affordability for a European capital.
