History
European settlement in Sydney began in 1788, and in 1800 Sydney had around 3,000 non-indigenous inhabitants. It took time for the city's population to grow-in 1851 its population was only 39,000, compared with 77,000 in Melbourne. The subsequent gold rushes in Victoria caused the population of Melbourne to increase rapidly, while the lesser gold rushes in New South Wales had a less profound effect on the population of Sydney. Sydney overtook Melbourne as Australia's most populous city in the early twentieth century, and reached the million inhabitants milestone around 1925. The opening of the Sydney Harbour Bridge helped pave the way for further urban development north of Sydney Harbour. Post-war immigration and a baby boom helped the population reach two million by 1962. Sydney remained Australia's most populous city throughout the 20th century, and is projected to retain this position for much of the 21st century. At the June 2016 Australian census, Sydney's population reached 5 million people.
Density
Sydney is particularly noted for its low population density, due to its history. Surrounded by land that was considered unowned by the city's founders, early Sydney enjoyed relatively low land values. Coupled with successive governments' willingness to release new land on the city's outskirts for further development, this history has given Sydney a low-density self-image.
Multiculturalism

At the 2016 census, the most commonly nominated ancestries were: At the 2016 census, there were 2,071,872 people living in Sydney that were born overseas, accounting for 42.9% of the population Sydney, above Vancouver, Los Angeles, New York City, Chicago, Paris and Berlin.

Sydney has been a hub of a number of migrant communities, such as the Lebanese, Fijian, Korean and Nepalese. Well over half of Australia's 25,000-strong Nepalese community, for example, is concentrated in Sydney. Seven out of every ten Lebanese migrants in Australia live in Sydney. The Ghanaian community has been noted as being quite visible in Sydney, with the number of Ghanaian churches being unusually large considering the relatively small number of Ghanaians in Australia.
