According to Statistics Canada, up to 244,000 English-speaking people have emigrated from Quebec to other provinces since the 1970s; those in Quebec whose sole native language was English dropped from 789,000 in 1971 to 575,555 in 2006, when they accounted for 7.6% of the population. Altogether, in 2006, 744,430 (10%) used mostly English as their home language, and 918,955 (12.2%) comprised the Official Language Minority, having English as their First Official language spoken. When many anglophones relocated outside of Quebec after the introduction of the Charter in the 1970s, several English-language schools in Montreal closed their doors. These school closures may also have been brought about by restrictions on who can attend English schools, which has been another ongoing drain on the English school system. Of the Anglophones between 25 and 44 years old who left the province between 1981 and 1986, 15000 individuals, which was half of this group, had university degrees. The provinces unemployment rate rose from 8.7 percent in 1976 to 10.4 percent in 1977, remaining above 10 percent for 19 of the last 23 years of the 20th century. The language barrier has also been regarded as a "soft cap" for population growth; for instance from 2013 to 2014 while Montreal gained around 43,000 immigrants from other parts of the world it lost 10,000 residents to other provinces.. In 2006, how many percent of residents did not use English as their home language?
