CSO Ireland: Historical Earnings
The Central Statistics Office publication, Historical Earnings 1938-2015, has compiled available average earnings data and presented them in as coherent a series as possible.
Earnings statistics have been produced in Ireland since the early nineteen hundreds, published in the Irish Trade Journal and Statistical Bulletin. Broad Industrial average earnings were first published in 1938. These statistics focused on Industrial employees in the Industry sector, where the majority of non-agricultural employment was based. Since then additional data has been published, including more occupational and sectoral categories.
