During the 18th and 19th centuries, 300,000 free emigrants and 45,000 convicts left Ireland to settle in Australia. Today, Australians of Irish descent are one of the largest self-reported ethnic groups in Australia, after English and Australian. In the 2006 Census, 1,803,741 residents identified themselves as having Irish ancestry either alone or in combination with another ancestry. However this figure does not include Australians with an Irish background who chose to nominate themselves as 'Australian' or other ancestries. The Australian embassy in Dublin states that up to thirty percent of the population claim some degree of Irish ancestry.
