Most Countries Overestimate Their Muslim Population
Perils Of Perception
The largest percentage point difference was recorded in France where respondents guessed that their country has 31 Muslims for every 100 people. In reality, however, the correct number is 7.5. In Germany where Angela Merkel recently called for a burqa ban, people overestimated the Muslim population to the tune of 16 percentage points. People in the U.S. guessed that there are 17 Muslims per 100 people whereas the actual number is just 1.
