Reliable socio-economic marine data is essential if policy makers are to use an evidence based approach to foster development of our ocean related industries. It is also vital if Ireland is to utilise its substantial marine resources in a manner that, as envisioned under the EU Blue Growth Strategy and Ireland’s Integrated Marine Plan, ensures a healthy marine environment and the continued delivery of marine ecosystem services to Irish society. With that in mind, this report provides a detailed analysis of Ireland’s ocean economy over time and presents a complete and comparable profile across thirteen marine related industries, which allows us to observe progress on the targets set out in the Government’s Integrated Marine Plan for Ireland - Harnessing Our Ocean Wealth (2012). The report includes a set of economic projections that forecast Ireland’s ocean economy up to 2018. It also provides a profile of Ireland’s coastal economy using Census of Population Small Area Statistics.
