The figure of the total population of each country is drawn from the global estimates listed in the CIA World Factbook , unless otherwise stated. Statistics describing the country’s linguistic, religious and ethnic demographics are based on its most recent national census. However, if these statistics are out-dated, unavailable, unreliable, or the country’s statistical department does not formally gather information on the categories listed, the Cultural Atlas substitutes the most recent global estimates cited in the CIA World Factbook .

The number of Australian residents that share ancestry with each country is based on the 2016 Australian Housing and Population census. This recorded people’s ancestry by the birthplace of their parents, not distant heritage.

The figure describing the country’s migrant population size in Australia is based on the number of Australian residents that were born in that country. Hence, this represents the population of first-generation migrants only, not the entire number of people living in Australia who identify with the culture in question.

All other statistical information on this country’s migrant population in Australia (the second section) reflects the 2011 Australian Census data. This was retrieved from the Department of Social Services’ Community Information Summaries . These 2011 figures will be updated with the forthcoming release of 2016 census data relating to migrant communities.
