Concern about terrorism varies significantly around the world, with the highest levels found in the Middle East, South Asia, and Western Europe—all regions that have suffered significant terrorist attacks. Despite 9/11, Americans are only average in their level of concern. Asked how big a problem terrorism is in their country, in sixteen out of forty-seven nations a majority or plurality said it was a very big problem; in fifteen nations a majority or plurality said it was at least a moderately big problem; and in thirteen nations a majority or plurality said it was a small problem or not a problem at all. An average of 41 percent of respondents across all countries polled said that terrorism is a very big problem in their country, while 23 percent said it was a moderately big problem, 19 percent said it is a small problem, and 14 percent said it is not a problem at all.
