The survey asked respondents about 88 fears across a broad range of categories including fears about the government, crime, the environment, the future, technology, health, disasters and many other personal anxieties.
The second annual Chapman University Survey on 'American Fears', that included more than 1,500 adult participants from across US, found that the top 10 things Americans fear the most are - corruption of government officials, cyber-terrorism, corporate tracking of personal information, terrorist attacks, government tracking of personal information, bio-warfare, identity theft, economic collapse, running out of money in the future and credit card fraud.
"The 2015 survey data shows us the top fears are heavily based in economic and 'big brother' type issues," said Christopher Bader, who led the team.
"People often fear what they cannot control and technology and the future of our economy are two aspects of life that Americans find very unpredictable at the moment," Bader said.
