Projections of the economy, nationally and regionally, were made having regard to:
■ projections of the global economy, including the principal countries/regions that Australia trades with, e.g. China, Japan, United States, India, Korea and Europe. Growth in real global GDP is projected to slow from 4.1 to 4.4 per cent per year over the period to 2019, to 3.7 per cent by 2031.
■ domestic demographic and economic data (outlined above); and
■ the distribution of population and industries across the 73 regions.
In the base case scenario, GDP is projected to grow by 84 per cent from $1,406 billion in 2011 to $2,583 billion in 2031.
