  • Methodology

    The National Tragedy Study was conducted by the National Opinion

    Research Center, University of Chicago. The first round of data collection began

    on September 13th, 2001 and ended on September 27th. It was a telephone

    interview of adults (18+) living in households with telephones in the United

    States. The total sample size of 2,156 comprised a national sample of 1,013

    households and additional samples in New York City (406 additional

    households), Washington DC (206 additional households), and Chicagoland

    areas (531 additional households). The overall response rate was 52 percent,

    with a 56 percent for the national portion of the survey, 50 percent for New York

    City, 41 percent for Washington DC, and 51 percent for Chicagoland areas. The

    second round of data collection began on December 18th, 2001 and ended on

    February 20th. The total sample size of 1,101 comprised a national sample of 805

    households and a New York City sample of 296 households. The overall

    response rate was 78 percent, with a 79 percent response rate for the national

    portion of the survey and 73 percent for New York City.

    Table 1 shows the obtained sample sizes and the AAPOR-defined

    response rates for the national and New York City samples for both round 1 and

    round 2. For Round 2, the rates are the percentage of Round 1 respondents that

    responded in Round 2. For Round 2, 9 respondents were too incapacitated to be

    interviewed and 146 were not able to be located during the field period.

    Separate weights were constructed to adjust for nonresponse based on

    age, sex, race and education. Wgt2b should be used with the national sample.

    Wgt2_nyc should be used with the New York sample. WASHWGT and

    CHMAWGT should be used with the Washington DC sample and Chicago

    sample, respectively. The weights are scaled to sum to an effective sample size

    based on inefficiency due to nonresponse adjustment. The overall design effect

    for the national sample was 1.55. The overall design effect for the New York

    sample was 1.80. Weights were not adjusted to account for nonresponse in

    round 2.

    SAMP is a variable that distinguishes the National (SAMP=1) sample from

    the New York City sample (SAMP=2). PANFLG is a binary variable that can be

    used to select the panel sample, that is, only those cases with data from both

    rounds.
