Small Area Population Estimates

The most recently published population estimates relate to mid-2006 and are available for Northern Ireland as a whole, and by Local Government District (LGD) and Parliamentary Constituency (PC). For smaller geographical units such as electoral wards and Census Output Areas (COAs), the estimation process becomes more complex, particularly in relation to migration.

The 2001 Census population figures are becoming more out of date as time goes on. Population estimates for COAs in mid-2003 were generated as part of the Northern Ireland Multiple Deprivation Measure 2005 to be used as denominators of deprivation indicators. It used the Ratio Method to construct population estimates by applying ratio changes in population indicators between 2001 and 2003 to the 2001 Census. These estimates were constraint to the LGD and PC mid-year population estimates. 

NISRA is currently undertaking a review of the methodology and data sources with regards to small area population estimates. New small area population estimates will be published here later this year.
