1971 LGA part code
This was a physical partition of an LGA used in 1971, such that each LGA Part contained about 10 CDs. An LGA Part can take values from 1 to 33 within an LGA.
The code value assigned to this field depends on the 1971 - 1976 CD comparability indicator.
a For CDs which are comparable between 1971 and 1976 (ie with comparability code of 0 or 1), the 1971 code is used;
b For 1971 CDs which have been split into parts for 1976, the 1971 code is used;
c For 1971 CDs which have been amalgamated for 1976, the 1971 code corresponding to the lowest field-code* value is used; where the 1971 CDs amalgamated include 1 or more confidential CDs the 1971 code corresponding to the lowest field-code* of the nonconfidential CDs is used;
d For CDs which are noncomparable and not in the above categories the code corresponding to the closest 1971 field code has been used.
* Note: field code was assigned for collection purposes in 1971 and is made up of a 6 digit numeric code comprising Census Division (2 digits), Census Subdivision (2 digits) and Collector's District (1971 CD Code) (2 digits).
