Survey Methods
Gallup surveys 1,000 national adults, aged 18 and older, every day and also conducts additional surveys. In most cases, the maximum margin of sampling error is ±2 to ±4 percentage points. For detailed survey methods on any results reported here, please visit the original story.
Interviews are conducted with respondents on land-line telephones (for respondents with a land-line telephone) and cellular phones (for respondents who are cell-phone only).
In addition to sampling error, question wording and practical difficulties in conducting surveys can introduce error or bias into the findings of public opinion polls.
