Here is an interesting set of data for some of the world's leading cities in terms of their contributions to country GDP and their share of total population. Sizes of the bubbles reflect the ratio of contribution to GDP to share of population. Greater Dublin is taken as per CSO: Dublin plus Mid-East region.
To me, this really does put into perspective the necessity for continued investment in the Greater Dublin region and the futility of our serial National Spatial Development Strategies.
We hear so much about the massive urbanization in the emerging economies, especially in the East. This process, in fact, is very much a reality. But what we do not hear about is urbanization of our own economic activity. The fact that Dublin stands out amongst the most urbanized zones, relative to the rest of the country, in the world is telling me that Ireland should focus more attention on developing the Greater Dublin region to reflect the reality of demand of the firms' and workers' for its location.
Updated: see the same chart with Dublin only:
Note: per CSO "The Mid East region (Kildare, Meath and Wicklow) and the Dublin region are affected by a substantial proportion of their workforce living in one region and commuting to work in another." That's as much of a 'definition' as we get to reflect the most likely fact that vast majority of commuters are to Dublin...
And here are the inputs that went into the above charts:
And the source for Dublin figures: National Accounts, regional incomes:
Notice that Dublin City's overall relative weight in the economy (ratio of share of GVA to share of population) rises relative to Greater Dublin, as expected, in line with the evident 'bedroom communities' nature of Mid-East region. Just look at the CSO figure for Mid-East share of GVA.
