Australia has many older people but not enough young people to care for them. What can we do?

Key points

• Australia's population is ageing, and children make up a smaller share of it. People aged 65 and over now make up 18 per cent of Australians.
• Birth rates have fallen to 1.48 babies per woman, well below the replacement level of 2.1. Fewer workers means fewer taxpayers, while more older people need care.
• Experts say there are no quick fixes, and that the country needs serious structural reform to share the burden fairly.
