See Other Territories. The Australian Standard Classification of Occupations (ASCO) defines a job as a set of tasks performed by one individual. An occupation is a set of jobs which requires the performance of a common set of tasks. See also Australian Standard Classification of Occupations (ASCO), Hours Worked (HRSP), Individual Income (INCP), Industry of Employment (INDP), Industry Sector (GNGP), Journey to Work (JTW), Labour Force Status/Status in Employment (LFSP), Method of Travel to Work (MTWP), Occupation (OCCP). Journey to Work data provide information on where a person works rather than where a person lives. The address of each employed person's usual workplace is used to code the work destination area. These destination areas are designed by the State Transport Authorities who require data on urban transport patterns to plan public transport systems. JTW data have been produced from Australian censuses since 1971. The JTW Study Areas and Destination Zones have been redefined for each Census to take into account changes and growth in the States and Territories. Consequently, JTW data are not comparable across Censuses. For the 2001 Census, there are important changes related to the geographic coverage and applicable population for JTW data that allow a more comprehensive view of work-related transport patterns across Australia. In previous censuses, JTW study areas were restricted to major urban areas in each State or Territory. For the 2001 Census, JTW coding has been expanded to encompass all of Australia (excluding External Territories). Each State and Territory are further defined as either Detailed or Extended study areas. The Detailed study areas cover the same major urban centres as defined for the 1996 Census, and comprise Destination Zones which aggregate to SLAs. The Extended study areas cover all remaining SLAs within the State/Territory. In 1996, JTW data were available only for those people who lived and worked in the same study area. Any person who was enumerated in a study area but gave a workplace address that was outside this study area was coded as 'Worked Outside Study Area'. For example, if a person commuted from Wollongong to work in Sydney, JTW data for that person could not be obtained. For the 2001 Census, the workplace address given by employed people is coded to an SLA and a Destination Zone if they work in a Detailed study area, or an SLA only if they work in an Extended study area. Destination zones do not concord with CDs but they do aggregate to SLAs. Working Population Profile tables provide characteristics of the working population for each SLA. JTW data can also be customised to provide flow tables containing both origin zone (by place of enumeration or place of usual residence) and destination zone. The origin and destination data can be cross classified with Method of Travel to Work (MTWP) to illustrate urban transport patterns. However, users should be aware of the difference in the time period covered by these variables. People employed in the week prior to the Census but no longer employed on census day still appear in JTW data. JTW information is derived from two variables: Journey to Work: Study Area (JTWSAP) and Journey to Work: Destination Zone (JTWDZNP). JTWSAP comprises State, Study Area Indicator (Detailed or Extended), and SLA. JTWDZNP comprises Destination Zone. Work Destination Zone codes are not unique throughout Australia and MUST be used in conjunction with JTW Study Area codes to produce meaningful JTW data.
