Population Growth and Distribution
Australia's population has been steadily increasing over the years, with a growth rate of 1.4% per annum. As of 2020, the estimated population of Australia is approximately 25.7 million people. The population is concentrated in the eastern and southeastern regions of the country, particularly in the states of New South Wales and Victoria. The population growth is driven by various factors, including natural increase (births minus deaths) and net overseas migration. The latter is a significant contributor to the country's population growth, with over 140,000 migrants arriving in Australia each year. The main drivers of migration are economic opportunities, family reunification, and humanitarian programs. To get a better understanding of Australia's population distribution, let's take a look at the following table:| State/Territory | Population (2020 est.) | Percentage of Total Population |
|---|---|---|
| New South Wales | 8,162,700 | 31.7% |
| Victoria | 6,693,400 | 26.1% |
| Queensland | 5,381,000 | 20.9% |
| South Australia | 1,784,800 | 6.9% |
| Western Australia | 2,745,800 | 10.7% |
| Tasmania | 541,300 | 2.1% |
| ACT | 431,100 | 1.7% |
| NT | 247,400 | 1.0% |
Age and Sex Distribution
The age and sex distribution of Australia's population is an important factor in understanding the country's demographics. As of 2020, the median age of the Australian population is approximately 38 years. The population is predominantly female, with a sex ratio of 96 males per 100 females. The age distribution of the population is as follows:- 0-14 years: 19.3%
- 15-24 years: 13.3%
- 25-34 years: 14.5%
- 35-44 years: 12.2%
- 45-54 years: 11.4%
- 55-64 years: 9.5%
- 65 years and over: 9.8%
Migration and Settlement Patterns
- Economic opportunities: 45%
- Family reunification: 25%
- Humanitarian programs: 15%
- Other reasons: 15%
Regional Variations
Australia's population is not evenly distributed across the country. The eastern and southeastern regions, particularly the states of New South Wales and Victoria, are the most populous. The western and northern regions, on the other hand, are relatively less populated. The regional variations in population density are as follows:| Region | Population Density (people per square kilometer) |
|---|---|
| New South Wales | 10.9 |
| Victoria | 7.4 |
| Queensland | 3.4 |
| South Australia | 2.1 |
| Western Australia | 1.9 |
| Tasmania | 1.4 |
| ACT | 1.2 |
