Project Methodology U.S. survey methodology The survey was designed by an independent team of experts on public opinion and foreign policy from the United States. Harris Interactive conducted 2,862 telephone interviews in the United States among men and women,18 years of age and older, using a random digit dialing technique with a national probability sample. In addition, personal in-home interviews with a national probability sample of 400 men and women 18 years of age and older were conducted using an abridged version of the telephone questionnaire. All interviewing of the general public was conducted between June 1 and June 30, 2002. Data for the telephone and in-person interviews were weighted separately according to known demographic characteristics of the population and merged to form a combined sample (n=3,262). The margin of error, at the .05 probability level, varies between 1.7 and 4 percentage points, depending upon whether the entire sample or a random subsample was asked a given question. Data prior to 2002, except for 1974, were collected by the Gallup Organization; Harris collected the 1974 data. The CCFR surveys have been conducted every four years since 1974. Ongoing analysis of the 2002 data has revealed some systematic differences between telephone and in-person responses, including a higher level of “not sure” responses in person. The combined data set mitigates these differences. In addition, in interpreting changes from the 1998 CCFR survey, conducted entirely in person, we have adopted the conservative strategy of underscoring only those changes that are apparent in both the telephone and the in-person 2002 data. Transatlantic survey methodology The survey was designed by an independent team of experts on public opinion and foreign policy from the United States and Europe. In the six European countries (Great Britain, France, Germany, Poland, Italy, and the Netherlands), MORI (Market & Opinion Research International) conducted 6,001 telephone interviews among men and women, 18 years of age and older using a random digit dialing technique. In each of the six European countries, 1,000 interviews were conducted (1,001 for France) with a nationally representative sample. The survey was conducted by telephone in all countries except Poland, where the telephone penetration is lower, and a face-to-face approach was used. All interviews were conducted between June 1 and July 6, 2002. For results based on the total sample in each of the six countries, one can say with 95% confidence that the error attributable to sampling and other random effects is +/- 3 percentage points. For results based on the total European sample, the margin or error varies between +/- 0.8 and +/- 1.4 percentage points. The figures given for Europe as a whole are weighted on the basis of adult population in each of the six countries surveyed.
