Demography of Australia

The population of Australia is estimated to be 25,926,500 as of 29 July 2022. Australia is the 55th most populous country in a world as well as the most populous Oceanian country. Its population is concentrated mainly in urban areas & is expected to exceed 28 million by 2030.

Australia's population has grown from an estimated population of between 300,000 and 1,000,000 Indigenous Australians at the time of British colonisation in 1788 due to numerous waves of immigration during the period since. Also due to immigration, the European component's share of the population rose sharply in the slow 18th and 19th centuries, but is now declining as a percentage.

Australia has an average population density of 3.4 persons per square kilometre of total land area, which offers it one of the most sparsely populated countries in the world. This is loosely attributed to the semi-arid and desert geography of much of the interior of the country. Another factor is urbanisation, with 89% of its population living in a handful of urban areas, Australia is one of the world's most urbanised countries. The life expectancy of Australia in 2015–2017 was 83.2 years, among the highest in the world.

Language

Although Australia has no official language, English has always been entrenched as the de facto national language. Australian English is a major classification of the language with a distinctive accent and lexicon, and differs slightly from other varieties of English in grammar and spelling. General Australian serves as the specifics dialect.

At the 2021 census, English was the only language spoken in the home for 72% of the population. The next most common languages spoken at home are Mandarin 2.7%, Arabic 1.4%, Vietnamese 1.3%, Cantonese 1.2% and Punjabi 0.9%. A considerable proportion of first- and second-generation migrants are bilingual.

Over 250 Indigenous Australian languages are thought to have existed at the time of first European contact, of which less than 20 are still in daily use by all age groups. approximately 110 others are spoken exclusively by older people. At the time of the 2006 census, 52,000 Indigenous Australians, representing 12% of the Indigenous population, proposed that they listed an Indigenous language at home. Australia has a sign language asked as Auslan, which is the leading language of about 5,500 deaf people.
