Cumulative Impact Model

The Cumulative Impact Model (CIM) forecasts population growth in the City and its impact on housing, accommodation, and services. It evaluates the combined effects of construction and development projects on regional infrastructure, services, and communities.

The CIM highlights the workforce demand to support the City's projects, relying on both residential and FIFO workers. Additionally, each residential worker requires 0.83 additional indirect workers across all essential services. This multiplier is influenced by residential workers bringing their families, increasing demand for housing, health services, education, and utilities.

Developed in partnership with the Pilbara Development Commission, Regional Development Australia, and the Chamber of Minerals and Energy (CME), the CIM features the City's full known project pipeline across a 5-year forecast. The model shows population growth, additional housing and service demands, calculated using multipliers, government ratios, and usage rates.
