Mr. John McCarthy:

I'm sure actually if you went out, even now, to try and get a data series in this area, it would be problematic because for house building, you simply go to a time series produced by the Department of the Environment. If you want to look at overall building and construction, you go to the CSO's databank. There is no one, single data point or data series that you can just go to. Instead you kind of have to amalgamate it yourself from a different ... from different sources and then you have to kind of quality adjust the figures as well, you know, what's the vacancy rate? You might get vacancy rates for the urban areas in terms of, you know, industrial units; what's the equivalent in rural areas?
