Mr. Pádraig Dalton:

Yes, we have that as well and Ms Cullen can get into the detail. With the other questions, in a sense it is about comparing data from the census with administrative data sources. As the Deputy highlighted, it is always difficult to compare data from different sources, whether it is an administrative data source, a survey or a census. The census was not designed to produce statistics on new builds or connections. One of the figures focused on by people is that of 33,000, which is the increase in the number of occupied dwellings built between 2011 and 2016. That, of course, excludes vacant dwellings that would have been built between 2011 and 2016. The other issue to note is there were 114,000 households where we did not get any information from the householder as to when the property was built. For that reason, we do not try to collect, or purport to collect, information on new builds, connections or completions. It is not the focus of the census as we do not have the information to allow us to do it. The figures of the Central Statistics Office and the Department measure two different things.
