Americans’ security concerns rose again this year.

Americans’ security concerns rose again this year with fears over terrorism and identity theft topping the list. In the U.S. Unisys Security Index, anxiety over security was at its highest level since the survey began in 2007. National security is the main worry with two-thirds of Americans seriously concerned over war and terrorism. However, the safety of infrastructure is also an issue. Approximately 59 percent of those surveyed were seriously concerned about the bridges, power plants, and pipelines.
