CA2009SLA_2006CD.txt is the text file containing the information concording 2006 Census Collection Districts to 2009 SLAs based on the area correspondence principal.
Note. These files are sometimes known as a CD 2006 to SLA 2009 correspondence, but the ABS express these in the format of 2009SLA from 2006CD because this is the order the data appears in the file.
Correspondence files are comma-delimited text files.
Field Names will vary from file to file but are consistent in nature. The field name is constructed from the area type and date. For example the code field from the 2009 SLA file will have the name "SLA_2009_Code", and the name field from the 2009 SLA file will have the name "SLA_2009_Name". It is important to note the placement/ positioning convention as it is similar to the file naming convention.
Percentage - figure expressed as a percentage ranges from 0 to 100
Ratio - figures expresses as part of 1 - actual figures can be up to 10 decimal places and are expressed in mathematical terms - 4.77810788750317e-04 which is 0.000477810788750317
An example of an SLA 2005 to SLA 2006 area based correspondence file would be:
105051100,Botany Bay (C),105051100,Botany Bay (C),0.9795,97.95
105051100,Botany Bay (C),105055200,Marrickville (A),1.4989195026137e-04,0.01
105051100”Botany Bay (C),105106550,Randwick (C),4.77810788750317e-04,0.04
The estimated value for Botany (2006) from 2005 SLA data would be
105051100 (Botany Bay) = 105055200 (Botany Bay) data multiplied by 0. 9795
105051100 (Botany Bay) = 105055200 (Marrickville) data multiplied by 0.0001
105051200 (Botany Bay) = 105106550 (Randwick) data multiplied by 0.0004
