Scope of Study

The National Survey of Disaster Experiences and Preparedness(NSDEP), 2007-2008 examined public preparedness, mitigation,

Summary:

avoidance actions, intended actions and perceptions of major hazardswith an emphasis on the hazards created by terrorism. Telephoneinterviews were conducted with 3300 United States residents between

April 13, 2007 and February 13, 2008. Information was collected ontopics such as terrorism, the government, knowledge about terrorism,and disaster/emergency planning and preparedness. Demographic andbackground variables included marital status, household composition,age, gender, education, country of birth, ethnicity, employment status,

and income.

survey dataData Type:

There are verbatim responses to question one in the survey. These havenot been deposited as they are embargoed until 2015. After 2015 they

will be deposited with this study.

Data Collection Notes:

This collection contains string responses which have been edited byICPSR in order to protect respondent anonymity and prevent disclosurerisk. These edited string responses have been provided in the zip filepkg34891-0001.zip.

Methodology

The purpose was to provide science-based information regardingperceptions of, preparations for, responses to, and recovery from terroristattacks, in the domestic U.S. context.

Purpose of the Study:

n/aStudy Design:

The sample was comprised of two strata: a high-visibility stratum and a

low-visibility stratum. High visibility areas were conceptualized as

Sample:

high-profile areas with highly visible targets, and thus can be consideredat high risk for terrorism. The high visibility stratum included the Districtof Columbia (DC, Arlington, Fairfax, Prince William, Loudoun,Montgomery, and Prince George's counties), Los Angeles County, andNew York City (Bronx, Brooklyn, Manhattan, Queens, and Staten Island).The low visibility stratum included the rest of the continental UnitedStates. Sampling within strata was proportional to size with the exceptionof the District of Columbia, which was over-sampled to protect againstunder-representation to achieve a sufficient number of complete

interviews for analysis. No specific geographic quotas were establishedfor the low-visibility stratum, and interviews were completed in roughproportion to the population for regions, states, and counties.Random-digit-dialing (RDD) was used in sampling. Telephone numberswere pre-screened for business numbers, pre-screened disconnectednumbers, and cell phones. Please refer to the Original P.I. Documentation

in the ICPSR Codebook for additional information on sampling.

The data are not weighted. However, the weight variables SAMPHHWTand RAKEDHHWT are present and may be applied to the data. Applying

Weight:

SAMPHHWT makes the sample unbiased, but only with respect to theresponding population. RAKEDHHWT sums to the sample size and canbe used in place of the original sampling weight, SAMPHHWT. Pleaserefer to the Original P.I. Documentation in the ICPSR Codebook foradditional information on weighting.

computer-assisted telephone interview (CATI)Mode of Data Collection:

The data consists of 415 variables that are centered around respondentsrecollection of terrorist events and natural disasters.

Description of Variables:

35 percent, calculated as the ratio of unweighted completion cases toestimated eligible cases. Please refer to the Original P.I. Documentationin the ICPSR Codebook for additional information on response rates.

Response Rates:

Standardized missing values.Extent of Processing:

Created online analysis version with question text.

Checked for undocumented or out-of-range codes.
