Survey: Terrorism fears drive more in U.S. to avoid crowds

Immediately after 9/11, 30% of Americans expressed reluctance to attend crowded events. That level of concern persisted throughout the first year after those attacks but dipped in polls conducted five years and 10 years later — to 23% and 27%, respectively. But with the recent events in England fresh in people’s minds, concern about attending crowded events is at a new high. Memories of other terrorist attacks on U.S. soil, including the 2013 Boston Marathon bombing and the 2016 shooting at the crowded Pulse nightclub in Orlando, Florida, also may be increasing Americans’ fears.

Since 9/11, Gallup periodically has asked Americans about their willingness to venture into four public situations in light of concerns that they may have about terrorism. In addition to attending events where there are thousands of people, the situations are traveling overseas, flying on airplanes and going into skyscrapers.
