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.
English diaspora
Australia's biggest city Sydney was founded by the British government as a penal colony. Visitors described the English character of Sydney for at least the first 50 years after 1788, noting the traditional English appearance of the churches overlooking the convict barracks. First-generation Sydney residents, other than the disappearing Aborigines, were predominantly English. 160,000 convicts came to Australia between 1788 and 1850. Between 1788 and 1840, 80,000 English convicts were transported to New South Wales, with the greatest numbers coming between 1825 and 1835. The New South Wales Census of 1846 accounted for 57,349 born in England.
