context: The largest population centres of the Sinhalese diaspora are mainly situated in Europe, North America and Australia. The city of Melbourne contains just under half of the Sri Lankan Australians. The 2011 census recorded 86,412 Sri Lanka born in Australia. There are 73,849 Australians (0.4 of the population) who reported having Sinhalese ancestry in 2006. The Sinhalese language was also reported to be the 29th-fastest-growing language in Australia (ranking above Somali language but behind Hindi language and Belarusian language). Sinhalese Australians have an exceptionally low rate of return migration to Sri Lanka. In the Canada 2011 Census, 7,220 people identified themselves as of Sri Lankan Canadians, out of 139,415 Sri Lankans. There are a small amount of Sri Lankans in India, scattered around the country, but mainly living in and around the North India and South India regions. Sri Lankan New Zealanders comprised 3% of the Asian population of New Zealand in 2001. The numbers arriving continued to increase, and at the 2006 census there were over 7,000 Sri Lankans living in New Zealand. The Sri Lankan American number about 12,000 in the U.S. The New York City Metropolitan Area contains the largest Sri Lankan community in the United States, receiving the highest legal permanent resident Sri Lankan immigrant population, followed by Central New Jersey and the Los Angeles metropolitan area. Many Sri Lankans in Italy have migrated to Italy since the 1970s. Italy was attractive to the Sinhalese due to perceived easier employment opportunities and entry, compared to other European countries. It is estimated that there are 30,000-33,000 Sinhalese in Italy. The major Sinhalese communities in Italy are located in Lombardia (In the districts Loreto and Lazzaretto), Milan, Lazio, Rome, Naples, and Southern Italy (Particularly Palermo, Messina and Catania). Though British Sri Lankans people in particular and Sri Lankans in general have migrated to the UK over the centuries beginning from the colonial times, the number of Sinhalese people in the UK cannot be estimated accurately due to inadequacies of census in the UK. The UK government does not record statistics on the basis of language or ethnicity and all Sri Lankans are classified into one group as Asian British or Asian Other.
