The National Survey of Disaster Experiences and Preparedness (NSDEP) examined whether households in the United States have engaged in proactive preparedness and avoidance activities since September 11, 2001, and whether the activities reported were done because of terrorism, natural disasters, other reasons, or any combination of reasons. Reported activities were examined by geographic area of exposure to or threat of 9/11, gender, race/ethnic identification, and income. The sample was drawn using random-digit-dialing (RDD) supplemented with surname lists. Data were collected between April 13, 2007, and February 13, 2008. Few households did preparedness and avoidance activities exclusively because of concerns about terrorism. Rather decisions were motivated by a combination of reasons. Residents of New York City and Washington, DC, men, and high-income respondents reported more preparedness activities, whereas low-income respondents, African Americans, and Hispanics reported more avoidance activities.
