Here's a cool chart I made using this software. It compares Ireland in 2009 and Ireland in 1962. Click on the image to enlarge it. You see the sectors that are 'big' in the economy in 1962, and those that are 'big' in 2009. The multinational presence is obvious, as is the continued presence of agriculture and services.
Very cool... Is this value added, employment or exports? I wonder can we find services data for 1962 also - growth of tradable services in Ireland one of the major developments of the last 15 years.
had a similar idea--compare 1980 to 1990 for example using that software--but they seem to be using some adjusted version of the CSO database. An email to the MIT guy might be in order.
