Journey to Work data is based on the 2006 Census Question: 'For the main job held last week, what was the person's workplace address?'
Self-containment measures the proportion of employed residents who are employed within the boundaries of the Local Government Area or region. It indicates the propensity of residents to seek employment outside the Local Government Area or region in which they live.
Self containment is likely to be higher for regional areas and, lower in metropolitan areas and is influenced by:
This dataset describes the work location (LGA) of employed residents of the area. It differs from the main journey to work dataset in that it shows simply the number and proportion of residents working in each industry who work within the area. Journey to Work data is created by cross tabulating a person’s main workplace address (Place of Work Data) with their place of usual residence to create a matrix of home to work. The data is presented at the LGA level. This information is generally not available at the small area (suburb/locality) level due to geographic limitations when being coded or processed.
Self containment is defined as the percentage of resident employed persons who work within the LGA or region. The data presented here shows a time series, allowing the user to see whether the level of self containment has increased or decreased over time. The change over time is presented as a change in percentage rather than absolute number, so that self-containment can be assessed independently from changes in the overall workforce in that industry.
Please note that Journey to Work coding has generally improved over time, so that the coding of location of employment in earlier Census years may not have the same quality as the more recent years. People who did not state their work location, or provided information which couldn’t be accurately coded, are excluded from the “employed in the city” column, and therefore the self-containment percentage. In this way, self containment levels could be affected by improved levels of geographic coding, and should be treated with caution.
