Census of Population and Housing 1986: Postcode Summary File
The Postcode Summary File summarises selected characteristics of persons, families and dwellings for each census postcode area as collected from the Census of Population and Housing, 30 June 1986; and allows the aggregation of any combination of census postcode areas.
The File contains, for each census postcode area, a series of counts of census characteristics of persons, families and dwellings grouped to form 46 statistical tables. Counts are on the basis of-place of enumeration, i.e. for each postcode area the counts are of persons who were enumerated in the area on census night.
For census purposes a postcode is assigned to each collection district (CD). Many CDs cross postcode boundaries. In such circumstances, the entire CD was allocated to the postcode in which the greater part of the CD population was estimated to lie. This procedure results in a degree of approximation in census counts relating to postcode areas.
Five postcode are across State borders. In these cases, a portion of the postcode has been allocated to each of the relevant States. Users wishing to work with whole postcodes must aggregate the components of the split postcodes (i.e. 2540, 2620, 3644, 3691 and 5751).
Postcode "0000" has been allocated to the Migratory category.
Note on Random Error
Small non-zero cells on this file have been randomly adjusted in an unbiased manner to avoid the release of identifiable data. This introduced error, in addition to possible respondent and processing errors, means that no significance can be attached to cells of three or less.
Random adjustment of small area data has also the following effects:
- more accurate statistics for census postcode areas will be obtained
directly from the PCSF than from aggregations of the Collection District
Summary File (CCDSF), which contains a larger number of adjusted cells; and
- totals between tables may not always be consistent.
The Postcode Summary File consists of 2432 logical records, one for each Australia Post postcode. Each logical record contains one record of geographic indicative information and 26 records containing counts or totals grouped to form 46 tables.
For each postcode area on the PCSF there are 27 records each 372 characters long.
The 27 records for each postcode area are identified by a character record type field, containing the values 00-26. Record type 00 contains the geographic indicative information-for the postcode area, in a format described below. Record types 01-26 contain the summary data for the postcode area. A later section describes the format of the summary data in more detail.
For some basic information about the way Census 86 was planned, designed, executed and processed, information on the person and dwelling characteristics included in statistical output and some guidance to other census products, see "Census 86 - How Australia Takes a Census".
The type 00 record is called the geographic indicative record. The structure of this record is as follows:
- Record type
- Space filler (consists of 15 spaces)
- Space filler (consists of 28 spaces)
- File name `CPCSF'
- Space filler (consists of 300 spaces)
The PCSF contains data from 46 summary tables, which present characteristics of persons, families and dwellings for every census postcode area in Australia. The tabulation basis is place of enumeration.
The 27 records for each postcode area are identified by a two character record type field containing the values 00-26. Record type 00 contains geographic indicative information for the postcode area in a format described above. Record types 01-26 contain the summary data for the postcode area.
Full details of the tables and cells are given in "Condensed Format Postcode Summary Tables Description File (download .rtf version)". The data cell values commence at 1, incrementing by 1 for each cell until 1535 is reached.
Cell numbers 486-7, 491-3, 536, 539-40, 57111- 574-5, 767, 783, 1327, 1435-42 and 1469-74 are not applicable and are set to zero. Cell numbers 675,678, 681,684, 693, 696, 699 and 702 are null cells due to change in design of the data base and are also set to zero.
These 1535 data cells are stored in record types 01-26. Each record consists of the 12 character header (containing the postcode, and record type indicator, followed by 60 cells each 6 characters long (12 + 60 x 6 = 372, the record length).
|Record type 01 contains cells 1 - 60|
|Record type 02 contains cells 61 - 120|
|Record type 03 contains cells 121 - 180|
|Record type 26 contains cells 1501 - 1535 (ie the first 35 cells)|
The remaining 25 cells are filled with the character `9'.
The structure of the data records is as follows:
