1971 Field Code
A 6 digit numeric code (2 digit Census Division, 2 digit Census Subdivision, 2 digit CD) allocated as follows to 1976 CD records:
1. For CD's which are comparable (i.e. which have comparability codes of 0 or 1--see following section describing Field 13 which gives details for 1971-1976 Comparability Indicator) between 1971 and 1976, the 1971 code is transferred directly
2. For 1971 CD's which have been split into parts for 1976, the 1971 code is transferred directly to both parts
3.For 1971 CD's which have been amalgamated for 1976, the 1971 field code with the lowest 6 digit field code value is transferred across. Where the 1971 CD's amalgamated include 1 or more confidential CD's the lowest 6 digit field code of the non-confidential CD's is transferred across.
4. For CD's which are non-comparable and not in the above categories, the closest approximate 1971 field code has been transferred across. In this case, the 1971 field code is only a guide to facilitate the location of the position of the 1976 CD on the 1971 Field maps
