This single infographic is filled with interesting information on Islam in Europe, from the % of respondents who think that Islam is not compatible with the West, the Muslim population, and public estimates of Muslim population. France has the highest Muslim population in Western Europe at 8%, but a 2014 poll found that the average French respondent thought the figure was 31%. These figures don't provide too much insight about how to address the challenges of multiculturalism, but understanding this demographic information may be the first step.
