Statement

A 2001 Census Area Statistic (CAS) sector was one of 2 special postcode sectors created for 2001 Census Output.

A postcode sector comprises all the unit postcodes that have the same identifier except for the last two characters. Special postcode sectors are created for census output to ensure sectors conform to a minimum threshold (20 households and 50 persons, the same minimum threshold as Census Output Areas) and do not cross Council Area boundaries.

First postcode sectors that cross council area boundaries are split and each part is treated as a postcode sector in its own right. Then using the master postcode of the OA, OAs are assigned to postcode sectors. Some sectors will have disappeared if they have not been assigned a master postcode but the resulting 1,010 aggregations were denoted CAS sectors and meet the minimum threshold for CAS. CAS sector cover Scotland and extend to the Mean High Water Mark (MHW)
