Countries in Australia

According to current estimates, Australia’s population will gradually rise for the remainder of the century. Australia’s population is estimated to be at 25.5 million people in 2020, with a predicted increase to 42.68 million people by 2099.

The population of Australia is growing at a pace of 1.18 percent, adding roughly 296,000 people to the people in 2019. This is due to net migration, which has averaged about 150,000 per year in recent years, and natural growth. The fertility rate in Australia is 1.83 births per woman, which is lower than the replacement rate of 2.1 births per woman.

In terms of population growth, Australia is ranked fifth among OECD nations. Like the other OECD nations with high growth rates, Australia has a significant labor demand that cannot be fulfilled domestically, necessitating mass migration.

According to the most recent United Nations figures, Australia’s current population is 26,043,960. The United Nations estimates a population of 26,068,792 on July 1, 2022.

Australia, the world’s sixth-biggest country, with a population density of just 3 persons per square kilometer, or 7 people per square mile. As a result, it is one of the world’s least densely inhabited nations. Mongolia, Western Sahara, and Suriname are the only countries with fewer inhabitants per square kilometer than Australia. Even less densely populated areas of Australia exist. In the Northern Territory, there are just 0.2 persons per square kilometer. As you can see from the density map higher down the page, most of Australia’s population is centered on or around the more favorable coastline regions.

The most recent Australian population census was in 2016 when the population of Australia was certified to be 23,401,892. The Australian Bureau of Statistics also offers the Australian Population Clock, which estimates the current population count based on population indices.

Australia Demographics

According to the 2011 Australian population census, 25.4 percent of the population claimed Australian ancestry out of 21,507,717. The percentage of people who claimed to be of English origin was 25.9% of the total population. Other percentages were 7.5 percent Irish, 6.4 percent Scottish, and 3.3 percent Italian.

Since World War I, Australia’s population has doubled, owing largely to immigration. Nearly 6 million immigrants arrived in Australia between the end of WWII and 2000, accounting for 2 out of every 7 Australians. Over 30% of Australians were born outside of Australia in the 2011 census, and over 46% had at least one parent born outside of Australia. The United Kingdom, New Zealand, China, India, and Vietnam are Australia’s most popular immigration sources.

Aborigines and Torres Strait Islanders accounted for about 548,000 people in 2011, or 2.5 percent of the overall population, up from 116,000 in 1976. This rise is partly because many persons with partial indigenous ancestry were previously undercounted.

Like those of other industrialized nations, Australia’s demographics are transitioning toward an older population. Australia’s median age is 37 years.

History of Australia’s Population

In 1770, Captain James Cook made a map of the land’s eastern coast and tried to claim it for Britain. The region was utilized as a prison colony for more than two decades, and when gold was discovered in New South Wales in 1851, the population swelled. By 1901, Australia had grown to six states, each with its constitution. After this period, the population rate soared to well over 2%, and the nation continued to expand at this pace until the 1970s when it began to settle down to the more manageable rate of growth of today.
