Geography

Welcome to the NISRA Geography web pages where you can access and download a range of maps and digital products that support the use of geography in developing statistics.

The Central Postcode Directory (CPD) relates both current and terminated postcodes in Northern Ireland to a range of statutory, administrative, electoral and other area geographies. It comes with a comprehensive guidance document to assist users.

Look-up tables have been designed to assist in the creation of statistics for Local Government Districts (LGD2014), District Electoral Areas (DEA2014), Settlements and the default urban-rural definition on an approximate basis using Small Areas or Super Output Areas as building blocks. Guidance documents for this process are also available. 

A range of digital products available for download are for use within both Geographic Information Systems (GIS) and also the main statistical software systems.

All products relate to the Irish Grid or Grid Square references.
