Results for the survey are based on telephone interviews conducted under the direction of Princeton Survey Research Associates among a nationwide, representative sample of 1,012 adults, 18 years of age or older, in France, 1,021 adults in Germany, 1,000 adults in Italy, 1,009 in Britain and 1,362 adults in the U.S. The fieldwork was conducted by Taylor Nelson Sofres in France between April 3-4, 2002, Emnid in Germany between April 3-6, 2002, Pragma in Italy between April 5-10, 2002, NOP in Britain between April 2-9, 2002, and Princeton Data Source in the U.S. between April 3-8, 2002. For results based on the total sample in each of the five countries, one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus 3.5 percentage points for each of the European countries, plus or minus 3 percentage points for the United States. In addition to sampling error, one should bear in mind that question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of opinion polls.
