The demographics of Quebec constitutes a complex and sensitive issue, especially as it relates to the National Question of Canada. Quebec is the only province in Canada to feature a francophone (French-speaking) majority, and where anglophones (English-speakers) constitute an officially recognized minority group. According to the 2011 census, French is the First Official language spoken of more than 85.5% of the population while this number rises to 88% for children under 15 years old. According to the 2011 census, 95% of Quebec is francophone, with less than 5% of the population not able to speak French.
Quebec is also home to "one of the world's most valuable founder populations", the Quebec Founder Population.Founder populations are very valuable to medical genetic research as they are pockets of low genetic variability which provide a useful research context for discovering gene-disease linkages. The Quebec Founder Population arose through the influx of people into Quebec from France in the 17th century to mid-18th century; though this influx was large, a high proportion of the immigrants either died or returned to France, leaving a founder population of approximately 2,600 people. About seven million Canadians (along with several million French Americans in the United States) are descendants of these original 2,600 colonists.
