e-mail: classifications.helpdesk@ons.gov.uk
3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)Fully implemented 01/01/2003
3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future.A major revision of the UK Standard Industrial Classification (SIC) will be published in 2007 in parallel with the major revision of NACE/ISIC. To inform the revision a process of consultation with data producers and users is in progress. The revision provides the opportunity to consider the structure and underlying methodology of the SIC. There is the option of a radical revision, if this meets the needs of users of statistics and is feasible to implement. Potentially, the impact will be major, both within and outside government.
