Surveys for the Pew Global Attitudes Project were conducted February 19-March 3, 2004 in nine nations under the direction of Princeton Survey Research Associates International. Telephone interviews were conducted among a nationwide, representative sample of 1,000 adults, 18 years of age or older, in the United States, 500 in Great Britain, 504 in France, and 500 in Germany. Face-to-face interviews were conducted among a nation-wide representative sample of 1,000 adults in Jordan, 1,002 in Russia, and 1,017 in Turkey. The sample in Morocco (N=1,000, ages 18-59) was exclusively urban, and the Pakistani sample (N=1,242) was predominantly urban. Face-to-face interviews were conducted in both nations.
For surveys where the sample size is 1000 or more (U.S., Russia, Jordan, Turkey, Morocco, Pakistan) one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus 3.5%.
For surveys where the sample size is approximately 500 (Great Britain, France, Germany) one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus 5%.
