ADDRESS CODING
Address information is essential for matching people between PES and Census data. Matching a person between the data sources is facilitated by the location of the dwelling where they were enumerated in PES, where they were included on a Census form and where they may have been included on a Census form.
Prior to processing PES data, each enumeration address will have a Collector Workload (CLW) and a Statistical Area Level 1 (SA1) associated with it, drawn directly from the re-coded sample. Each 'search address', that is, an address where a person may have been included on a Census form for which the PES can search, will be coded with a CLW and SA1, using the AddressCoder@ABS application.
In 2011, the coding of addresses has become even more important to the processing of the PES than in previous cycles. The introduction of Automated Data Linking (ADL) has made it necessary to have a Census enumeration area that can be used as a filtering variable for a number of the ADL runs, which requires a single SA1 to be identified. In addition to this coding, attention must also be given to ensuring the accuracy of other address elements (e.g., street names, suburbs and postcodes).
The CLW is important for subsequent match and search processing as it is the default starting point for dwelling and person searching.
