Ireland’s population data was gathered from the country’s Central Statistics Bureau website. The website only published data for a limited number of years and thus projections had to be applied to fill in the missing years. Our population projections are based on two projection models: The Monte Carlo simulation model and the Autoregression Integrated Moving Average (ARIMA) models. Additionally, using historical trends, and assuming the current activity prevails, we were able to establish a reasonable expectation for predicting future population values.

We then applied multiple configurations of each of the two models to find out which model (and which configuration within that model) was most accurate for each of Ireland’s counties.

Ireland’s employment estimates and projections are based on the country’s 2016 census obtained through the Central Statistics Bureau. Ireland records their occupation to the UK SOC 2010 classification, with minor variants.

When creating the occupation supply projections, we took the expected population growth rate from the models mentioned above and applied that same growth rate across the LMI in each county. Once we had the projections, we mapped the UK SOC 2010 classification to Global Occupations.
