Survey Methods:
Results are based on telephone interviews with 1,027 national adults, aged 18 and older, conducted Jan. 30-Feb. 1, 2009. For results based on the total sample of national adults, one can say with 95% confidence that the maximum margin of sampling error is ±3 percentage points.
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).
