POPULATION – A FUTURE CHALLENGE FOR AUSTRALIA

Current and Future Australian Population Trends and their Implications

Growth Rates

Since the beginning of the 20th century, Australia’s population has increased five-fold, this will increase to between 24-28 million in 50 year’s time, with the pace falling in about ten years time (Figure1). The highest growth occurred after WWII and the lowest in the 1930s coinciding with the Great Depression (Table1).

Natural increase has attributed to two-thirds of Australia’s population; fertility and morality rates have undergone significant changes due to increasing proportions of couples restricting their family size to one, two or no kids at all and falls in mortality rates of children and of mothers in childbirth. The third factor contributing to population growth, overseas migration has fluctuated substantially playing a significant role in absolute numbers and the number of their children.

Age Structure

Throughout the last century the population has aged steadily, apart from a reversal in the 1947-1971’s post-war baby boom. Projections indicate that Australia’s population will continue to age, an inevitable result of low fertility levels and increasing life expectancy. This means that more Australians will be retiring from the labour force than joining in the future.

Spatial Distribution

Australian’s population have mainly lived near the coast due to the harsh conditions of Australia’s climate.

In the 1980s, the number of people living close to the CBD had declined dramatically because of inner-city urban decay forcing people to head for a life in suburb areas. After the government initiated policies to renew the decaying cities, people returned. This trend is continuing today, with 64% of the population residing in the capital cities.

Multicultural Country

The population changed dramatically after the introduction of the White Australian Policy. The beginnings of ethnic diversity occurred after WWII, Australia has become one of the most ethnically diverse countries in the world. The proportion of all Asian migrants has increased from 9% to 44% between 1981 and 2008.

Ecological Sustainability

There are many people who argue that Australia cannot support a larger population because of Australia’s poor conditions. Many problems have arisen over population growth such as waste disposal, air pollution, over-development on coastal areas, environment degradation, and salinity. Intense development on Australia’s coastal areas, both ...
