In 2008, the INSEE (National Institute of Statistics and Economic Studies) estimated that the total number of foreign-born immigrants was around 5 million (8% of the population), while their French-born descendants numbered 6.5 million, or 11% of the population. Thus, nearly a fifth of the country's population were either first or second-generation immigrants, of which more than 5 million were of European origin and 4 million of Maghrebi ancestry. In 2008, France granted citizenship to 137,000 persons, mostly from Morocco, Algeria and Turkey.
