What This Means for Taxpayers
Ireland has a population of approximately 5.38 million people. Dividing the total tracked overrun of €12.9B across the population equates to over €2,400 per person — money approved by the Dáil beyond original project budgets.
These are not estimates — every figure is sourced from official government records. The Comptroller and Auditor General's annual report, departmental Revised Estimates, and Dáil written answers form the basis of all data.
