2010 CORRESPONDENCES PRODUCT BRIEF
* in some cases the Area type is two characters, eg "CD", adjust character count appropriately For Example CA2010SLA_2006CD.txt is the text file containing the information concording 2006 Census Collection Districts to 2010 SLAs based on the area correspondence principal. Note. These files are sometimes known as a CD 2006 to SLA 2010 correspondence, but the ABS express these in the format of 2010SLA from 2006CD because this is the order the data appears in the file. File Format 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 2010 SLA file will have the name "SLA_2010_Code", and the name field from the 2010 SLA file will have the name "SLA_2010_Name". It is important to note the placement/ positioning convention as it is similar to the file naming convention. Percentage - figures expressed as a percentage ranges from 0 to 100. Ratio - figures expressed 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 An example of an SLA 2005 to SLA 2006 area based correspondence file would be. “SLA_2006_Code”,”SLA_2006_Name”,”SLA_2005_Code”,”SLA_2005_Name”,”Ratio”,”Percent” 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 plus 105051100 (Botany Bay) = 105055200 (Marrickville) data multiplied by 0.0001 plus 105051200 (Botany Bay) = 105106550 (Randwick) data multiplied by 0.0004 Copyright Commonwealth of Australia administered by the ABS For enquiries please contact the ABS Geography Section, see details below.
