(4.3 percent) and 1910 (4.1 percent). At this time, immigration from the British Isles increased, supplemented by a rapid increase in immigration flows from continental Europe, especially Germany, Scandinavia, and the Soviet Union. In 2001, 250,640 people immigrated to Canada, relative to a total population of 30,007,094 people per the 2001 Census. Since 2001, immigration has ranged between 221,352 and 262,236 immigrants per annum. In 2017, the Liberal government announced Canada will welcome nearly one million immigrants over the next three years. The number of migrants would climb to 310,000 in 2018, up from 300,000 in 2017. That number was projected to rise to 330,000 in 2019, then 340,000 in 2020. Accordingly, between 2017 and 2018, net immigration accounted for 80% of Canada's population increase. The three main official reasons given for the level of immigration were: The social component – Canada facilitates family reunification. The humanitarian component – Relating to refugees. The economic component – Attracting immigrants who will contribute economically and fill labour market needs. Canada's level of immigration peaked in 1993 in the last year of the Progressive Conservative government and was maintained by the Liberal Party of Canada. Ambitious targets of an annual 1% per capita immigration rate were hampered by financial constraints. The Liberals committed to raising actual immigration levels further in 2005. As Canadian political parties have been cautious about criticizing high levels of immigration, immigration levels to Canada (approx. 0.7% per year) are considerably higher per capita than to the United States (approx. 0.3% per year). Furthermore, much of the immigration to the US is from Latin America and relatively less from Asia, though admitting about twice as many immigrants from Asian countries (e.g. China, India, the Philippines, and Pakistan) as Canada. As such, the Hispanic/Latin American population makes up the largest minority group in the United States, whereas such is true for the Asian population in Canada. Immigrant population growth is concentrated in or around large cities (particularly Vancouver, Toronto, and Montreal). These cities have experienced increased service demands that accompany strong population growth, causing concern about the capability of the infrastructure to handle influxes in such places. For example, as noted in a Toronto Star article from 14 July 2006, 43% of Canada's immigrants move to the Greater Toronto Area and that, "unless Canada cuts immigrant numbers, our major cities will not be able to maintain their social and physical infrastructures."
