楼主的文章应该是引用的下面这篇文章的数据，不过我有点奇怪，技术移民的工资其实真没有这么低。
Immigration study ranks low-income rates in Canada by source country
Recent Chinese, South Korean and Taiwanese immigrants are among the mostly likely to have low incomes, but few use social assistance, Citizenship and Immigration Canada finds.
Immigrants from China, South Korea and Taiwan have among the lowest incomes in Canada, but few of them use social assistance, according to an internal government study.
Based on the 2011 National Household Survey data, Citizenship and Immigration Canada examined the incomes of immigrants from 52 countries, accounting for 86 per cent of the overall immigrant population, to measure which were more likely to have lower incomes.
People from the Netherlands, the United Kingdom, South Africa, Ireland, Italy, Germany, Australia, the Philippines, Croatia, Portugal, Serbia and India did as well or better than native-born Canadians, the study said.
At the other end of the spectrum, almost one-fifth of those from China, Haiti, Pakistan, Ethiopia, Turkey, Colombia, Iran, Morocco, Afghanistan, Bangladesh, Algeria, South Korea, Iraq and Taiwan lived below the low income cut-off ($18,759 for a single person in Toronto).
The study explained the struggles these poorer immigrants face: They’re more recent newcomers; are less likely to speak English or French fluently; are younger, urban and working age; possibly less educated; and come from countries that produce more refugees.
“Those with better language skills and already with jobs here can assure economic success,” said immigration policy analyst Richard Kurland, who obtained the data through a freedom of information request. “It is all about their skills, not their skin.”
It’s not publicly known who asked for the study, or for what purpose, but Kurland said Ottawa has increasingly relied on tax data to tinker with and enforce its immigration laws; for example, people who wish to maintain permanent resident status or apply for citizenship must submit income tax returns as proof of their physical presence in Canada.
“The government uses tax data to make immigration policies that bring in more people, and more taxes,” said Kurland.
“The trends are (that) we are seeing a decrease in the number of refugees — a group prone to social assistance use — and we now have an extended financial obligation for Canadians who sponsor their parents and grandparents to Canada.”
The study found that immigrants from Taiwan, South Korea and China used government assistance at rates of just 2 per cent, 5 per cent and 5 per cent respectively — below the 10 per cent average. Almost half of the Taiwanese immigrants and 29 per cent of South Korean immigrants were admitted to Canada through the business immigration class.
University of Toronto immigration studies professor Jeffrey Reitz explained the low usage as due to the “lack of knowledge and culture” among new immigrants about Canada’s social safety net.
“It can be due to the culture in their own country, where depending on government handouts is disreputable,” said Reitz. “But over time, they assimilate and use welfare in Canada.”
Kurland, the immigration policy analyst, believes it may have more to do with the particular circumstances of these immigrants, which often have some members of the family living in Canada and others in their home countries.
However, critics doubt the reliability of the data from the national survey — which, unlike the old mandatory long-form census, can skew the results if respondents don’t bother to answer the optional questionnaire.
Debbie Douglas, executive director of the Ontario Council for Agencies Serving Immigrants, said other challenges such as minority ethnicity, race and religion also affect immigrants’ job prospects.
“There is a need for programs and services that will support economic integration of immigrants and refugees, as well as movement on the employer side so that more immigrants are hired at their skill level,” said Douglas.
