The information is based on Form A - Household Schedule.

This feature layer was created using Census 2016 data produced by the Central Statistics Office (CSO) and NUTS 3 boundary data (generalised to 100m) produced by Ordnance Survey Ireland (OSi). The layer represents Census 2016 theme 2.3, the population usually resident in Ireland by usual residence 1 year before Census Day. Attributes include population breakdown by usual residence (e.g. same address, outside Ireland). Census 2016 theme 2 represents Migration, Ethnicity and Religion. The Census is carried out every five years by the CSO to determine an account of every person in Ireland. The results provide information on a range of themes, such as, population, housing and education. The data were sourced from the CSO. NUTS 3 boundaries generalised to 100m. The Nomenclature of Territorial Units for Statistics (NUTS) were drawn up by Eurostat in order to define territorial units for the production of regional statistics across the European Union. The NUTS classification has been used in EU legislation since 1988, but it was only in 2003 that the EU Member States, the European Parliament and the Commission established the NUTS regions within a legal framework (Regulation (EC) No 1059/2003). The Irish NUTS 3 regions comprise the eight Regional Authorities established under the Local Government Act, 1991 (Regional Authorities) (Establishment) Order, 1993 which came into operation on January 1st 1994. The NUTS 2 regions, which were proposed by Government and agreed to by Eurostat in 1999, are groupings of the Regional Authorities.
