The NSW Central Cancer Registry records the residential address of all persons with cancer at the time of diagnosis. On the basis of this address, a National Locality Index code (NLI) is applied that determines the Local Government Area of residence at the time of diagnosis of all cases and subsequently, the Area Health Service of Residence.

The NSWCCR is an historical database of all cases of cancer diagnosed in NSW from 1972 to 2004.
Currently the entire database is coded to 1991 Local Government boundaries. To update to 2001 boundaries, all addresses on the CCR would need to be remapped to 2001 boundaries so that numerator and population denominator information is compatible.
