Sydney
Under the reign of Queen Victoria federation of the six colonies occurred on 1 January 1901. Sydney, with a population of 481,000, then became the state capital of New South Wales. The Great Depression of the 1930s had a severe effect on Sydney's economy, as it did with most cities throughout the industrial world. For much of the 1930s up to one in three breadwinners was unemployed. Construction of the Sydney Harbour Bridge served to alleviate some of the effects of the economic downturn by employing 1,400 men between 1924 and 1932. The population continued to boom despite the Depression, having reached 1 million in 1925.
Demographics 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.
