Ireland uses two major administrative divisions: counties and cities, both classified as Eurostat LAU 1 areas.  Additionally, there are two types of statistical area: Regions and regional authorities (NUTS 2 and NUTS 3). 

Reporting is not entirely consistent with Eurostat standards.  Some datasets are reported as city-county aggregates that do not conform to any NUTS level (there are four such aggregates).  However, the Dublin Regional Authority is also a city-county aggregate (including Dublin City), but is classed as a proper NUTS 3 area.

The official Eurostat definitions of NUTS (Nomenclature of Territorial Units for Statistics) are online.

Please see the related article for the metropolitan areas defined by Moody's Analytics for the purposes of our Global Metros estimates and forecasts.

Table 1. Geographic types for Ireland and Data Buffet geo codes.  For example, all four aggregates of counties are identified with IIRL_(digit)(digit)(letter)(letter).  The geo wild card IIRL_^^^^ cannot differentiate between counties and aggregates of counties; please use a geo list instead.

Table 2. Ireland geographic hierarchy and geo codes.  The geography codes assigned by Moody's Analytics appear in red in the first column.  Eurostat levels and codes are in the three rightmost columns.
