The most recent official figure is 3.8 practising doctors per 1 000 population (≈38 per 10 000), slightly below the 40 per 10 000 claimed; the MEP rounded up.
The claim cites no reference year; the closest available data (2023/2024 reference period) gives 3.8 per 1 000.
If used to imply a strong health workforce, the claim omits that Ireland's physician density remains BELOW the EU average of 4.3 per 1 000, as noted in the same OECD source.
The two sources located (both OECD publications) are not fully independent of one another, as they draw on the same OECD/Eurostat health-statistics dataset.
