Survey Methods

The survey in Mexico is part of the larger Spring 2011 Pew Global Attitudes survey conducted in 22 countries and the Palestinian territories under the direction of Princeton Survey Research Associates International.

Results for the survey in Mexico are based on 800 face-to-face interviews of adults conducted March 22 to April 7. The survey uses a multi-stage cluster sample stratified by Mexico’s geographical regions and urban/rural population. All interviews were conducted in Spanish.

The margin of sampling error is ±4.5 percentage points. 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.
