Abstract
Almost every record of an individual’s contact with the NSW
health system contains some form of spatial information,
whether a street address or postcode. This information can
be used to assign a geocode to the record, which in turn can
be used to examine the spatial distributions of disease and
health service utilisation. This article describes a study that
compares two different methods of geocoding addresses from
routinely collected administrative health data to enable small
area analysis.
