As the Deputy will be aware, there is a wide variety of people involved in different aspects of the aviation industry in Ireland, both directly and indirectly, and my Department would not have data on the numbers involved. The collection of national statistics is a matter for the Central Statistics Office, which is the official agency for that purpose. However, as regards the three State airports, I am informed by the airport authorities for Dublin, Shannon and Cork that their estimate of the numbers employed, both by themselves and by other employers, including airlines operating from the airports, is in the region of 15,500, 1,500 and 3,200 respectively.
