Dublin continued to have the highest disposable income per person at €27,688 - 18 % higher than the state average.
CSO figures show that Limerick had the second highest while Donegal recorded the lowest income per person, at just over €18,300.
More than a third of all employed persons in the country worked in Dublin and 12% worked in Cork.
The figures also show that Cork and Dublin benefit largely from the presence of key economic sectors, for example, the Information & Communication sector in Dublin and the Industry sector in Cork.
