Most Mexicans See Better Life in U.S. - One-In-Three Would Migrate
Results for the survey are based on face-to-face interviews conducted May 26 to June 2, 2009. The survey in Mexico is part of the larger 2009 Pew Global Attitudes survey conducted in 24 nations and the Palestinian territories from May 18 to June 16, 2009, under the direction of Princeton Survey Research Associates International. (For more results from the 25-nation 2009 poll, see “Confidence in Obama Lifts U.S. Image Around the World,” released July 23, 2009.)
The table provides details about the survey’s methodology, including the margin of sampling error based on all interviews conducted in Mexico. For the results based on the full sample, one can say with 95% confidence that the error attributable to sampling and other random effects is plus or minus the margin of error. 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.
