Detailed Characteristic (DC) Postcode Sector

A DC sector is one of 2 special postcode sectors created for 2011 Census Output.

In order to release more in-depth census information, DC sectors have been created with a minimum threshold of 400 households and 1,000 persons. Any Local Characteristic (LC) sector that failed to meet the thresholds was merged with its smallest adjacent neighbours(s) within the same council area until the DC sector requirements were satisfied.

More information on Detailed Characteristic Sectors can be found in the 2011 Census Geography Background Information note within the 2011 Census Supporting Information section of the NRS website.
