The latest Intergenerational Report shows Australia less old than it was going to be, but poorer. And eventually needing to pay more tax.
The Australian government has just released the latest iteration of its Intergenerational Report, the since the first was published in 2002.
Each provides a snapshot of the sort of Australia in which future generations will find themselves in 40 years鈥 time, should current government policies continue.
Previous reports have dealt mainly with the impact of an older age profile on government budgets and our way of life. This one also made space for the impact of climate change.
The good news for future budgets in this report is that, although Australia鈥檚 population will still age rapidly, it is expected to age more slowly than previously thought.
The chart below shows the projections in each of the six reports for the proportion of the population aged 65 and over.
In 2002, the first intergenerational report predicted that by 2023 the share of the population aged 65 and over would have climbed from 12.5% to nearly 19%, and then would rise to 24.5% by 2042.
Yet, in the intervening years, Australia saw an unanticipated migration boom, which slowed that rate of ageing so that today only 17.3% of the population is aged 65 and over, and the projection for 2063 is 23.4%, less than the 24.5% originally expected for 2042.
These updated projections suggest that by 2063 Australia鈥檚 population will be younger than that of Italy now, or Japan a decade ago.
And ageing will slow further if net migration climbs higher than the 235,000 per year assumed in the latest report. A more reasonable migration assumption might be that it will in fact increase alongside increases in the total population.
The projections for labour force participation (the proportion of the adult population who are either working or making themselves available for work) have become more optimistic with each intergenerational report.
While participation is still expected to drop, the latest projection is for more of a glide than a dive, leaving participation higher in 2063 than it was in 2002.
As the report puts it, participation is projected to decline from a record high of 66.6% in 2023 to 63.8% by 2063.
The gentle slope of the decline reflects offsetting forces. More of us will be older and less able to work, but within most age groups, more of us will be in work.
More optimistic demographic projections and sensible policy choices have resulted in less extreme increases in age-related spending.
Spending on pensions is projected to fall rather than climb as a share of the economy, falling from 2.3% to 2% of GDP. This is by design.
While in other countries pensions are more generous and increase with earnings, in Australia the age pension is more modest and reduces with means.
By pairing the age pension with superannuation, which increases people鈥檚 means in retirement, pension spending falls.
By the 2060s, pension spending in Australia will be less than half the rate of the next lowest-spending OECD country (though admittedly that comparison ignores tax expenditures on super).
Government spending on health as a proportion of GDP is still projected to increase, from 4.6% now to 6.2% in 2063, but is expected to remain well short of the first intergenerational report鈥檚 projection of more than 8% by 2042.
Only 40% of this projected increase in health spending is due to ageing, which ought not to be the least bit surprising.
As people and societies grow richer and satisfy more of their basic needs, they naturally want to spend more of what they have on extending their lives and improving their health, demanding more and better healthcare from government.
Spending on aged care is set to grow more than many other types of spending, albeit from a low base.
The Intergenerational Report has it doubling from 1.1% of GDP in to 2.5% in 2063.
The projection may well be an underestimate. Governments are yet to fully respond to demands for greater quality of care set out in the report of the .
When it comes to resources for meeting the needs we need to meet, the Nobel prizewinning economist Paul Krugman famously noted in 1994 that productivity wasn鈥檛 everything, but in the long run it was 鈥溾.
Productivity growth, and assumptions about future productivity growth, have continued to decline with almost every intergenerational report.
The assumption for long-term productivity growth in this report is 1.2%, down from 1.75% in the 2002 intergenerational report.
The difference this makes is enormous. The 2002 intergenerational report had living standards (GDP per person) climbing 90% in 40 years. This latest intergenerational report has them climbing only 57% in the next 40 years.
While slower ageing means this report predicts the government鈥檚 future budget deficits will be lower than those projected in all previous reports bar one, the budget is expected to be in a deepening deficit for much of the next 40 years.
Naturally, this can be fixed with more tax, but the projected lower rate of productivity growth means there will be relatively less to tax than was expected in the first intergenerational report in 2002.
Launching the report at the National Press Club, Treasurer Jim Chalmers talked about the need for action now on multiple fronts, saying there would 鈥渘ever be a quiet time to think about the future鈥.
But on raising more tax he was silent, suggesting it was a question for the future.
