French polling agency IFOP published the results of a survey on Europeans and Islam. The survey 'How Europeans see Islam' was conducted April 9-18, 2011 through online questionnaires in Germany, the Netherlands, France and the UK, with relatively low samples of 600-800 people in every country.
In those four countries, a plurality think that the presence of a Muslim community in their country represents a threat for their country's identity (47% in the UK, 44% in the Netherlands, 40% in Germany, 42% in France). In France and more so in the UK, a higher proportion of youth under 35 tended to regard the presence of Muslims as a factor of cultural enrichment. In Germany the Netherlands the youth were more critical of Islam then those over 35.
But IFOP says the results hide a more nuanced reality: more than 50% said they either thought the Muslim community was an enriching factor (19% in the UK and Netherlands, 24% in Germany, 22% in France) or that it was neither option (34% in the UK, 37% in the Netherlands, 36% in Germany and France).
