17 years after 9/11, terror attack is top concern for Americans, says Hill.TV poll

Americans say terrorism is their top concern 17 years after the Sept. 11 attacks, according to a new American Barometer survey. 

The poll, conducted by Hill.TV and the HarrisX polling company, found that 26 percent of respondents listed terrorism when asked what they thought was the biggest threat to the U.S.

Fifteen percent of Americans said they thought cyber attacks posed the greatest threat to the country, while 12 percent listed a financial crisis as a top concern.

Nineteen percent listed "something else" when asked about the country's biggest threat. 

The survey comes on the 17th anniversary of the attacks on Sept. 11, 2001, in New York City, Washington and Pennsylvania. 

The attacks left nearly 3,000 people dead, and over 6,000 injured. 

Several smaller-scale terror attacks have taken place in the U.S. since 9/11, including the Boston Marathon bombings in 2013, the San Bernardino shooting in 2015 and the Orlando Pulse Nightclub shooting in 2016. 

"Terrorism attacks are something Americans have seen whether they were alive for 9/11 or not, and is something that I think is more top of mind, then say a nuclear attack," Ipsos research director Mallory Newall told Hill.TV's Joe Concha on "What America's Thinking."

The American Barometer poll was conducted Sept. 8-9 among 1,000 registered voters and has a margin of error of 3.1 percentage points.
