TPA Workforce (by place of residence) projections by Travel Zone for the Sydney Greater Metropolitan Area (GMA).

TPA provides projections of workforce at the small area (Travel Zone or TZ) level for the Sydney Greater Metropolitan Area (GMA).

The GMA includes the Sydney Greater Capital City Statistical Area (GCCSA), the Southern Highlands and Shoalhaven SA4, Illawarra SA4, Newcastle and Lake Macquarie SA4, and Lower Hunter, Port Stephens, and Maitland SA3s, as defined by the Australian Bureau of Statistics (ABS).

The projections in this release, TZP2016 v1.51, are five-yearly, from 2016 to 2056. The visualisations are presented in 2011 Travel Zone geography.

TPA workforce projections relate to usual residents of the GMA aged 15 years and over who are employed. They are estimates of employed people based on where they reside. TPA also produces employment projections based on the workplace or job location. They refer to persons aged 15 years and over, working in the GMA regardless of their place of usual residence. The majority of the persons employed in the GMA also reside in the GMA.

Factors considered in the estimation of workforce projections include: population by age and gender; participation rates; unemployment rates; historical labour force data; past trends of employment in each industry and the forecasts of industry growth or decline in each region.

The above Travel Zone Projections for Workforce are available for download in both Excel and CSV formats from the Open Data Hub.

When modelling a potential future land use distribution, it should be understood there is no one single future or a single way to interpret the available data. TPA’s TZ projections seek to represent the most likely future trends for the GMA, based on current data, trends and an understanding of policy/structural changes as at November 2016. They use a “statistical, population-based time series” modelling approach. They provide “fit for purpose” projections that are designed to assist with transport planning, modelling, and the development of business cases for major transport infrastructure and other strategic purposes.

It should be noted that projections for the distant future are significantly more difficult to predict with certainty. Transport's TZ projections between 2021 and 2036 are supported by various forecasts and strategic plans from both government and non-government organisations. For projections beyond 2036, there is limited relevant input data available and the model has developed projections in line with identified trends.
