2001 Controlled Access Microdata Sample Test file
The Test file is available under the same access conditions as the 2001 Licensed Individual SAR and the SAM. You must be registered with the Census Registration Service.
Variables have been perturbed to ensure that no sample members can be identified. Perturbation has retained the correct distribution of each variable but the relationships between variables will not give expected results. The test file can therefore be used to develop and test syntax for analyses before going to use the CAMS at ONS. It cannot be used to test exploratory analyses with any reliability, nor will you be able to test statistical procedures which are dependent on distributions. It is not suitable for research purposes and has been provided only as a dummy dataset for preparing syntax in advance of using the CAMS file.
