Ms Deirdre Cullen:

With regard to extrapolating, we collected data for approximately 57,000 of the 183,000 dwellings and the question was whether one could extrapolate that out. We deliberately did not do that. The notes were taken by the enumerators to assist them with their work. They wrote themselves notes to say, for example, that they should call back on Thursday at 2 p.m. or they took the householder's phone number, as members will attest. Householders engaged with their enumerator. Sometimes, if the enumerator could not get an answer he or she spoke to the neighbour and jotted it down in the book but we do not know what the blank panels mean and so we deliberately did not extrapolate out from that. I would be wary of doing that.

With regard to holiday homes, as Mr. Dalton said, one should be careful of percentage increases. The determination of a holiday home would clearly be easier to do in Courtown, Westport or Achill Island, it is harder to do in Dublin city centre. Country people can have holiday homes in Dublin in the same way Dublin people can have holiday homes down the country and so one relies on information from neighbours. That said, we have seen an increase and there is no doubt part of that is due to Airbnb. It is there and we are aware of it.

In regard to Deputy Coppinger's comment about hoarding, the data we are bringing out tomorrow will enable local authorities to zone in on where the vacancy is and whether dwellings are detached, semi-detached, terraced, apartments or whatever else. That will be down to street level - as good as. A small area will have 100 dwellings and people will be able to zoom in very quickly. The digital boundaries for those small areas are going up tomorrow as well. People who can manipulate the data will be able to zone in and get the data. That is as far as we can go. In terms of Deputy Coppinger's comment on hoarding, we cannot surmise.

We did put up data about Blacklion as part of the report and that was just a flavour of the type of data we can produce. People then went out and walked the streets of Blacklion and they could see the new houses up there that nobody was living in so I presume local housing officers will continue that work.
