A 2001 Standard (ST) ward is one of 2 special wards created for 2001 Census Output. These are both created by aggregating output areas and are only best-fit for electoral wards.
Where 2001 Census Area Statistic (CAS) wards fall below the ST thresholds (400 households and 1,000 persons) they are merged with neighbouring CAS wards to exceed the threshold. It is also necessary to make a few adjustments to ST wards so as to remove and ‘slivers’ below ST threshold created by differencing ST wards and ST sectors. The processes result in 1,176 ST wards.
