About the Survey

Results for this survey are based on telephone interviews conducted under the direction of Princeton Survey Research Associates International among a nationwide sample of 1,503 adults, 18 years of age or older, from March 19-22, 2008. The following table shows the error attributable to sampling that would be expected at the 95% level of confidence for different groups in the survey:

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.

Some material in this report was taken from the Pew Research Center’s weekly News Interest Index survey (N=1,015) conducted March 20-24, 2008. An abbreviated topline for this survey appears at the end of this report.
