ASGC-RELATED PRODUCTS AND SERVICES
National Localities Index (NLI)
The National Localities Index, Australia (cat. no. 1252.0.55.001) is a coding tool designed to assist users assign the ASGC Main Structure codes to street address information. Once coded to the ASGC Main Structure direct comparisons to other ABS statistical information may be made. The NLI is updated regularly and maintained in accordance with each edition of the ASGC.
The NLI consists of two parts - a Localities Index and a Streets Sub-Index. The Localities Index contains a list of all Localities in Australia. In broad terms, a Locality is a place where people live or work - or say they live or work. Localities are assigned their full ASGC Main Structure code (i.e. S/T, SD, SSD and SLA codes). The majority of Localities lie wholly within one SLA but where they are split between two or more SLAs, street information is recorded in the Streets Sub-Index.
The NLI index files are available as ASCII, comma deliminated text files with fixed field lengths, suitable for downloading into personal and mainframe computers. These can be downloaded from the ABS web site free of charge.
