2011 Census - The relationship between statistical and administrative geographic units and area measurements guidance note

Date published: 28 February 2013



The statistical geographic units for 2011 Census outputs have been designed in such a way that they are based on, and fully nested within, the current administrative units (the wards and Local Government Districts introduced in 1992). Thus Small Areas (statistical unit) nest within Super Output Areas (statistical unit) which in turn nest within electoral wards (administrative unit).
