In June 2022, it was estimated that around 7.3 percent of Australians were aged between 25 and 29, and the same applied to people aged between 30 and 34. All in all, about 55 percent of Australia’s population was aged 35 years or older as of June 2022. At the same time, the age distribution of the country also shows that the share of children under 14 years old was still higher than that of people over 65 years old. A breakdown of Australia’s population growth Australia is the sixth-largest country in the world, yet with a population of around 26 million inhabitants, it is only sparsely populated. Since the 1970s, the population growth of Australia has remained fairly constant. While there was a slight rise in the Australian death rate in 2022, the birth rate of the country decreased after a slight rise in the previous year. The fact that the birth rate is almost double the size of its death rate gives the country one of the highest natural population growth rates of any high-income country.
National distribution of the population Australia’s population is expected to surpass 28 million people by 2028. The majority of its inhabitants live in the major cities. The most populated states are New South Wales, Victoria, and Queensland. Together, they account for over 75 percent of the population in Australia.

The statistic shows the total population of Australia from 1980 to 2021, with projections up until 2029. In 2021, Australia had a total population of about 25.77 million people. Population of Australia Australia is among the ten largest countries in the world, in terms of area size, although its total population is low in relation to this. Much of Australia’s interior remains uninhabited, as the majority of Australians live in coastal metropolises and cities. Most of the population is of European descent (predominantly British), although there is a growing share of the population with Asian heritage; only a small percentage belongs to the indigenous Aboriginal population. Australia's year-on-year population growth is fairly high compared to most other economically and demographically advanced nations, due to comparatively high rates of natural increase and immigration. Living standards Standard of living is fairly high in Australia, which can be seen when looking at the Human Development Index, which ranks countries by their level of human development and living standards, such as their unemployment rate, literacy rate, or life expectancy at birth. Life expectancy of Australia’s population is quite high in international comparison, for example, Australia is also among the leading countries when it comes to this key factor.

Economically speaking, Australia is also among the leading nations, with a steadily rising employment rate, an increasing gross domestic product (GDP) with a steady growth rate, and a relatively stable share in the global GDP.

About this dataset

Context

The dataset tabulates the Au Train township population over the last 20 plus years. It lists the population for each year, along with the year on year change in population, as well as the change in percentage terms for each year. The dataset can be utilized to understand the population change of Au Train township across the last two decades. For example, using this dataset, we can identify if the population is declining or increasing. If there is a change, when the population peaked, or if it is still growing and has not reached its peak. We can also compare the trend with the overall trend of United States population over the same period of time.

Key observations

In 2023, the population of Au Train township was 1,022, a 0.10% decrease year-by-year from 2022. Previously, in 2022, Au Train township population was 1,023, a decline of 0.39% compared to a population of 1,027 in 2021. Over the last 20 plus years, between 2000 and 2023, population of Au Train township decreased by 138. In this period, the peak population was 1,160 in the year 2000. The numbers suggest that the population has already reached its peak and is showing a trend of decline. Source: U.S. Census Bureau Population Estimates Program (PEP).
