Small Areas are a relatively recent geographic concept compiled by the National Institute of Regional and Spatial Analysis (NIRSA) on behalf of the Ordnance Survey Ireland (OSi) and in consultation with the CSO. They were designed as the lowest level of geography for the compilation of statistics in line with data protection guidelines and typically contain between 50 and 200 dwellings. A further constraint imposed when creating these new areas, was that they nested within Electoral Division boundaries. Finally, they are generally comprised either of complete townlands or neighbourhoods.

Small area vacancy data

Census 2016 identified 183,312 dwellings as being vacant. This dataset investigates these dwellings looking at:

  • The type of dwelling.
  • The status of these dwellings in Census 2011 (where available).
  • The reason why these dwellings were vacant (where available) in Census 2016.


82,437 of the 183,312 vacant dwellings were occupied during Census 2011. This dataset also investigates these dwellings, looking at the data recorded in that census with regards to:

  • Age of the head of the household.
  • Number of usual residents.
  • Household composition.
  • Period built.
  • Nature of occupancy.
  • Number of rooms.
  • Number of persons per room.


The data is presented for the 2017 version of the Small Areas (18,641 areas).  Statistical disclosure control has been applied to some areas, resulting in total figures being present for these areas but no further information provided in the breakdown.
