Statistics were researched in 2007 by the South Korean Ministry of Foreign Affairs and Trade. The statistics showed that among Koreans living in Canada, 86,084 are Canadian citizens, 72,077 are permanent residents, 20,738 people have student visas, and 19,271 other people are temporary residents. The Canada 2001 Census said that there are 101,715 Canadians of Korean descent, but Korean community leaders and the media think that there are more than this. A big group could be temporary students studying English. According to the Canada 1996 Census, 53.6% of Korean immigrants to Canada graduated from University, compared to 23% of other Canadians. However, because Canadian employers prefer degrees from Canada, Korean immigrants often do jobs that are not what they studied in Korea; 40% worked in family-owned businesses, and their average income is only 67% of other Canadian's income.
