CD Confidentiality Indicator
This is a code which indicates whether or not the CD is
i A confidential CD, in which case all information contained in the 10 summary tables will be contained in the CD indicated by the Receiving CD field. A confidential CD thus has population and dwelling information set to zero.
ii A receiving CD, in which case the CD will contain, combined with its own information, all information which would have appeared in Table 2 to 49 of a confidential CD.
The possible code values and their meanings are:
O Not applicable 1 Confidential CD 2 Receiving CDThe eight character field for a confidential CD consists of the confidentiality indicator (code 1) followed by the State (1 character), and the Census Division, Census Sub-division and CD (each two characters) of the receiving CD.
Where the receiving CD and the confidential CD have different geographic indicatives (the Study Area Code, Postcode etc), both CDs retain their original indicative information, but the data for the confidential CD now added into a receiving CD with, for example, a different Postcode, will be reported against the Postcode of the receiving CD.
