An Annual Index of Irish Industrial Production, 1800-1921

We construct an annual index of Irish industrial output for 1800-1921, the period during which the entire island was in a political Union with Great Britain. We also construct a new industrial price index. Irish industrial output grew by an average of 1.4 per cent per annum over the period as a whole, and by 1.8 per cent per annum between 1800 and the outbreak of World War I. Industrial growth was more rapid than previously thought before the Famine, and slower afterwards. While Ireland did not experience deindustrialization either before the Famine or afterwards, its industrial growth was disappointing when considered in a comparative perspective.
