But what is Dublin? As Dr Hughes sees it, the capital necessarily includes not only the historic city and county, but also Meath, Kildare and Wicklow. Together, they constitute what has become known as the Greater Dublin Area even though nobody in, say, Oldcastle, Co Meath, would see it that way. So it is not the case, as one newspaper report this week portrayed it, that Dublin - as a city - or even as a metropolitan area might have a population of nearly two million at the end of the next decade. What is true is that the eastern region, which already has a disproportionately large share of the Republic's population, will become more dominant.
