What are Common Planning Assumptions?

Agreed information assets for use by NSW Government and others, to prepare proposals, business plans and strategies that rely on projections

The Common Planning Assumptions are agreed information assets (data sets, models and analytical tools) for use by NSW Government, and others, to prepare proposals, business plans and strategies that rely on projections.

Various NSW Government agencies are custodians of information assets and responsible for their development and maintenance. Common Planning Assumptions ensures that information is shared and used across Government. This reduces duplication of effort and provides a consistent basis for policy development and service delivery planning. Common Planning Assumptions are not targets or scenarios.

The data sets include population growth, economic growth, housing supply, metropolitan transport demand, and freight demand. There are also guidelines for employment projections, and future temperature and climate events.

The Common Planning Assumptions are used in the development of new policies, strategies or business cases.  They were used to prepare key Government plans in 2017, including:

  • Future Transport 2056
  • State Infrastructure Strategy 2018 - 2038
  • Greater Sydney Region Plan and District Plans.

The planning horizon for these data sets and projections is typically between 20 years (business cases for investment above $10 million) and 40 years (proposals for major investments and strategies).
