Census of Population and Housing, 1976: Aboriginal Collection District Summary Files
The Aboriginal Collection District Summary Files present summary characteristics of Aborigines and Torres Strait Islanders and the dwellings in which they live, for every Collection District (CD) where there are at least 10 Aboriginal or Torres Strait Islander people and 4 or more dwellings where an Aborigine or Torres Strait Islander was present on Census night. (When data is not available for an area because it does not meet this confidentiality criteria it is aggregated to the next highest non-confidential level).
The records for each CD include geographic area codes for State, Statistical Division, Statistical Subdivision/District, LGA, LGA Section, Destination and Origin Zones, State Area, Section of State, Commonwealth Electoral Division (1977 boundaries), State Electoral Division, Postcode, Locality, Census Division, Census Subdivision, 1976 CD, 1971 LGA and LGA Part, 1971 CD, and a 1971-1976 CD comparability indicator. The table information is made up of 47 tables giving data for both persons and dwellings. The tables include counts for males and females by marital status, usual major activity, usual residence, ages, religion, educational institution attending, age left school, highest qualification, income, duration of marriage, total issue, occupation, occupation status, hours worked, number of jobs, mode of travel to work, family type, child minding facilities used, pensions or benefits received; and dwelling counts by type of dwelling, material of walls, number of rooms and bedrooms, facilities, number of vehicles, power or fuel used, nature of occupancy, weekly rent, sources of mortgages, mortgage payments, structure of building and reason unoccupied.
The Summary Files contain 3 files of aboriginal CD summary data. File A holds data for NSW and Vic., File B holds data for Qld and SA, File C holds data for WA, Tas., NT and ACT.
Each of the 4498 logical records contains one record of geographic indicative information and 9 records containing counts or totals grouped to form 47 tables.
File A contains 1873 records. File B contains 1483 records. File C contains 1142 records.
Each of the 3 Aboriginal CD Summary Files contains 10 records for each CD. The first record contains 26 cells of geographic indicative information. The next 9 records contain 1250 cells of counts of summary information for persons and dwellings. There is a total of 4498 logical records. File A contains data for NSW and Vic.

The table information is made up of 47 tables containing a total of 1250 cells giving data for both persons and dwellings.

The following notes were issued by the ABS concerning tables from the Aboriginal Collection District Summary Files.
The part of Table 5 which shows the 1971 usual residence of the population has been found to have errors in most categories. Although, on a small area basis, the error may not be significant, it is suggested that users contact the ABS if they require detailed information about the types of errors involved.
Table 13 which shows the number of people attending educational institutions by the type of institution has been found to be in error. The number of persons attending schools and other institutions has been understated by persons who said they attended a school or other institution but did not state the name of the institution (ie. type of institution was not stated). It is suggested that users contact the ABS if they require detailed information about the type of errors involved.
