The National Survey of Disaster Experiences and Preparedness (NSDEP), 2007-2008 examined public preparedness, mitigation, avoidance actions, intended actions and perceptions of major hazards with an emphasis on the hazards created by terrorism. Telephone interviews were conducted with 3300 United States residents between April 13, 2007 and February 13, 2008. Information was collected on topics such as terrorism, the government, knowledge about terrorism, and disaster/emergency planning and preparedness. Demographic and background variables included marital status, household composition, age, gender, education, country of birth, ethnicity, employment status, and income.

Data Collection Notes:
There are verbatim responses to question one in the survey. These have not been deposited as they are embargoed until 2015. After 2015 they will be deposited with this study.
This collection contains string responses which have been edited by ICPSR in order to protect respondent anonymity and prevent disclosure risk. These edited string responses have been provided in the zip file pkg34891-0001.zip.

Study Purpose: The purpose was to provide science-based information regarding perceptions of, preparations for, responses to, and recovery from terrorist attacks, in the domestic U.S. context.
Sample: The sample was comprised of two strata: a high-visibility stratum and a low-visibility stratum. High visibility areas were conceptualized as high-profile areas with highly visible targets, and thus can be considered at high risk for terrorism. The high visibility stratum included the District of Columbia (DC, Arlington, Fairfax, Prince William, Loudoun, Montgomery, and Prince George's counties), Los Angeles County, and New York City (Bronx, Brooklyn, Manhattan, Queens, and Staten Island). The low visibility stratum included the rest of the continental United States. Sampling within strata was proportional to size with the exception of the District of Columbia, which was over-sampled to protect against under-representation to achieve a sufficient number of complete interviews for analysis. No specific geographic quotas were established for the low-visibility stratum, and interviews were completed in rough proportion to the population for regions, states, and counties. Random-digit-dialing (RDD) was used in sampling. Telephone numbers were pre-screened for business numbers, pre-screened disconnected numbers, and cell phones. Please refer to the Original P.I. Documentation in the ICPSR Codebook for additional information on sampling.
Weight: The data are not weighted. However, the weight variables SAMPHHWT and RAKEDHHWT are present and may be applied to the data. Applying SAMPHHWT makes the sample unbiased, but only with respect to the responding population. RAKEDHHWT sums to the sample size and can be used in place of the original sampling weight, SAMPHHWT. Please refer to the Original P.I. Documentation in the ICPSR Codebook for additional information on weighting.
Mode of Data Collection: computer-assisted telephone interview (CATI)
Description of Variables: The data consists of 415 variables that are centered around respondents' recollection of terrorist events and natural disasters.
Response Rates: 35 percent, calculated as the ratio of unweighted completion cases to estimated eligible cases. Please refer to the Original P.I. Documentation in the ICPSR Codebook for additional information on response rates.
