Australia in 2045

In 2045, Australia is projected to have a population of 31,431,122 people. Ten years before, in 2035, the projected population is 29,296,168 — 7.3% lower. With a projected median age of 42.7 years, Australia would have a youth dependency ratio of 25.5 and an old-age dependency ratio of 37.3 per 100 people of working age. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
