Health, wealth and housing: here’s what forecasters think Australia will look like in 2066

What is Australia’s intergenerational report, and what does it try to predict?

Australia’s intergenerational report is a long-term forecast of the country’s likely population and economic conditions. The article describes it as a predicted snapshot of life in 2066. It matters because today’s decisions about work, services and public spending can shape future generations.

The report considers major forces acting together. These include population growth, lower fertility, an ageing population, artificial intelligence, climate change and geopolitical tensions. For example, it projects Australia reaching 40 million people while fewer people have children. That combination can change the balance between workers and retirees.

The report is not a guaranteed picture of the future. Projections depend on assumptions about fertility, migration, life expectancy, technology and economic conditions. Still, they help governments identify pressures early. The article’s central message is that Australia may become larger, older and more technologically changed by the 2060s.

How large is Australia’s population expected to be in 2066?

Australia is expected to have a population of about 40 million people in 2066. This is the central population estimate highlighted in the article. The number shows that Australia can continue growing even as family sizes become smaller.

Population size is not determined by births alone. It also reflects the number of people already living in the country, how long people live and migration. A large existing population can keep adding people through births for many years. New arrivals can also increase the total. These forces can outweigh a lower average number of children per family.

The projection also describes a major shift in population structure. Australia will not simply be bigger; it will be older, with fewer babies being born. That matters for schools, workplaces, healthcare and government budgets. The 40 million figure is therefore part of a wider warning about how population growth may occur.

What does it mean that Australians will be older and having fewer babies?

An older population means older people will make up a larger share of Australia’s total population. Having fewer babies means the average family size is shrinking and fewer children are entering the population. These trends are related but different. One concerns age structure; the other concerns birth rates.

For example, if families have fewer children for many years, smaller groups eventually reach working age. At the same time, people living longer means more people remain in older age groups. The result can be a different balance between workers, children and retirees. The article captures this change by saying Australia will be older and have fewer people having even fewer babies.

This does not mean every Australian will be old or that births will stop. It means the population’s proportions will change. Over time, the shift can affect employment, healthcare demand, retirement arrangements and public spending. It also helps explain why the report focuses on intergenerational pressures.

Why can a population grow even when each family has fewer children?

Population growth depends on more than the number of children each family has. It reflects births, deaths and migration, as well as the population’s existing age structure. A country can therefore add people even when the average family has fewer children.

For example, a large group of young adults can have children, creating many births even if each family has only one or two. People living longer also keep the total population larger. Migration can add people directly, including workers and families. These mechanisms can produce growth while fertility is falling. This effect is sometimes called population momentum.

Australia’s article gives this pattern a clear example. It projects 40 million people in 2066 while also describing fewer babies. The total can rise, but the population may still age. Eventually, if low fertility continues and migration or longevity do not offset it, growth may slow or stop. The report highlights why total size and population structure must be considered together.

What happens to work, healthcare and government spending when the share of older people increases?

When older people make up a larger share of the population, demand often rises for healthcare, aged care and income support. At the same time, fewer working-age people may be available to provide services and generate tax revenue. This creates pressure on the relationship between public income and public spending.

For example, older people are more likely, on average, to need medical treatment, medicines or long-term care. If the number of retirees grows faster than the number of workers, governments may need to spend more while receiving taxes from a smaller relative workforce. They could respond through productivity, migration, later retirement, policy changes or higher revenue, though the article does not specify particular measures.

The report says Australia’s older population will be working harder. That points to a future where longer working lives may help meet labour needs and support budgets. The precise costs are not given, but the direction is clear: ageing can reshape healthcare, employment and government priorities.

How might Australia’s workforce change as it faces an older population and the expansion of artificial intelligence?

An older population can reduce the share of people entering the workforce, especially when fewer babies are born today. The article says Australians in the 2060s will be older and working harder. At the same time, artificial intelligence will rapidly change tasks, occupations and workplace expectations.

AI may help employers produce more with fewer workers. It could automate routine tasks, support decision-making and improve productivity. However, it may also replace some tasks and create demand for different skills. Older workers may need accessible training, flexible jobs and workplace adjustments so they can remain productive for longer. These are general implications; the article does not identify specific occupations.

The future workforce may therefore be smaller relative to the population but more technology-enabled. Australia’s challenge will be combining human experience with new tools. Policies and employers may need to support lifelong learning, safe AI adoption and longer careers. The report places this workforce change alongside ageing, climate risks and geopolitical tensions.

What are population projections, and why can they change when fertility, migration, life expectancy, climate conditions or economic trends change?

Population projections estimate how many people may live in a country and what age groups they may belong to. They use assumptions about fertility, mortality and migration, often extending those trends into the future. They matter because governments use them to plan schools, hospitals, housing, transport, jobs and budgets.

For example, if fertility falls faster than expected, fewer children may enter future classrooms and workforces. If life expectancy rises, more people may reach older ages. Higher migration can increase population size, while economic weakness may change migration and family decisions. Climate conditions can influence where people live, migration patterns, health and mortality. Each change can alter the projected result.

Australia’s 2066 figure of 40 million is therefore a forecast, not a certainty. The article also identifies climate change, AI and geopolitical tensions as future pressures. New evidence or unexpected events could change the assumptions. Projections are most useful as planning tools that show possible needs and risks.
