For the past three years Chapman University, located in Orange, California, has surveyed Americans about their top fears. The most recent survey, conducted in April 2016, asked a random sample of 1,511 adults* their level of about 80 different fears categorized within 11 domains: crime, economic, environment, government, illness and death, immigration/demographic changes, human-made disasters, natural disasters, personal fears, relationships, and technology. Below are the top 10 fears for which the highest percentage of people surveyed reported being “Afraid” or “Very Afraid.”
