United States of America

From 1850 to 1930, the foreign born population of the United States increased from 2.2 million to 14.2 million. The highest percentage of foreign born people in the United States were found in this period, with the peak in 1890 at 14.7%. During this time, the lower costs of Atlantic Ocean travel in time and fare made it more advantageous for immigrants to move to the U.S. than in years prior. Following this time period immigration fell because in 1924 Congress implemented a quota system in which each country was only allowed to have 2% more immigrants per year based on their respective numbers in 1890. The Immigration Act of 1924 favored immigrants from Northern European countries that already had many immigrants in the U.S. by 1890.[48] Immigration continued to fall throughout the 1940s and 1950's, but it increased again afterwards. but was still low by historical standards.[49] After 2000, immigration to the United States numbered approximately 1,000,000 per year. In 2006, 1.27 million immigrants were granted legal residence. Mexico has been the leading source of new U.S. residents for over two decades; and since 1998, China, India and the Philippines have been in the top four sending countries every year.[50] The U.S. has often been called the "melting pot"(derived from Carl N. Degler, a historian, author of Out of Our Past), a name derived from United States' rich tradition of immigrants coming to the US looking for something better and having their cultures melded and incorporated into the fabric of the country. Emma Lazarus, in a poem entitled "The New Colossus," which is inscribed on the pedestal of the Statue of Liberty tells of the invitation extended to those wanting to make the US their home.

New Zealand

New Zealand has relatively open immigration policies. 23% of the population was born overseas, mainly in Asia, Oceania, and UK, one of the highest rates in the world. In 2004-2005, a target of 45,000 immigrants was set by the New Zealand immigration Service and represented 1.5% of the total population. According to the 2001 census projections, by 2050 57% of all New Zealand children will have Maori or Pacific ancestry, while 68% will be non-European

Australia

The overall level of immigration to Australia has grown substantially during the last decade. Net overseas migration increased from 30,000 in 1993[44] to 118,000 in 2003-04.[45] The largest components of immigration are the skilled migration and family re-union programs. In recent years the mandatory detention of unauthorised arrivals by boat has generated great levels of controversy. During the 2004-05, total 123,424 people immigrated to Australia. Of them, 17,736 were from Africa, 54,804 from Asia, 21,131 from Oceania, 18,220 from United Kingdom, 1,506 from South America, and 2,369 from Eastern Europe.[38] 131,000 people migrated to Australia in 2005-06[46] and migration target for 2006-07 was 144,000.

Japan

Japan accepted just 16 refugees in 1999, while the United States took in 85,010 for resettlement, according to the UNHCR. New Zealand, which is smaller than Japan, accepted 1,140 refugees in 1999. Just 305 persons were recognized as refugees by Japan from 1981, when Japan ratified the U.N. Convention Relating to the Status of Refugees, to 2002.[41][42] Japanese Minister Taro Aso has called Japan a "one race" nation.[43] This comment was heavily criticized by both Japanese and foreign media

Canada

Canada has the highest per capita net immigration rate in the world,[37] driven by economic policy and family reunification. In 2001, 250,640 people immigrated to Canada. Newcomers settle mostly in the major urban areas of Toronto, Vancouver and Montreal. By the 1990s and 2000s, a majority of Canada's immigrants came from Asia.[38] Canadian society is often depicted as being a very progressive, diverse, and multicultural. Accusing a person of racism in Canada is usually considered a serious slur.[39] All political parties are now cautious about criticising of the high level of immigration, because, as noted by the Globe and Mail, "in the early 1990s, the old Reform Party was branded 'racist' for suggesting that immigration levels be lowered from 250,000 to 150,000

Portugal

Portugal, long a country of emigration,[35] has now become a country of net immigration, and not just from the former colonies; by the end of 2003, legal immigrants represented about 4% of the population, and the largest communities were from Cape Verde, Brazil, Angola, Guinea-Bissau, UK, Spain and Ukraine

Spain

Spain is the most favoured European destination for Britons leaving the UK.[30] Since 2000, Spain has absorbed more than three million immigrants, growing its population by almost 10%. Immigrant population now tops over 4.5 million. According to residence permit data for 2005, about 500,000 were Moroccan, another 500,000 were Ecuadorian,[31] more than 200,000 were Romanian, and 260,000 were Colombian.[32][33] In 2005 alone, a regularisation programme increased the legal immigrant population by 700,000 people
