The Controlled Access Microdata Sample (CAMS) is a file containing more detail than the 2001 Individual Licensed SAR. It can only be accessed in a safe setting within ONS, subject to an approval process.
For information on how to apply for access go to the ONS web site. Informal queries should be addressed to sars@ons.gsi.gov.uk.
Charges
A charge is applicable for use of the CAMS but use of the CAMS to academic researchers is now free (except for work contracted by government or private organisations). This decision is based on negotiations with the ESRC and is backdated to 1 December 2006.
