Survey Methodology

Zogby International conducted an omnibus telephone survey of [adults].

The sample is [1000 adult] interviews with approximately [44] questions asked. Samples are randomly drawn from telephone cd’s of national listed sample. Zogby International surveys employ sampling strategies in which selection probabilities are proportional to population size within area codes and exchanges. Up to six calls are made to reach a sampled phone number. Cooperation rates are calculated using one of AAPOR’s approved methodologies[i] and are comparable to other professional public-opinion surveys conducted using similar sampling strategies.[ii] Weighting by [region, party, age, race, religion, gender] is used to adjust for non-response. The margin of error is +/- 3.2 percentage points. Margins of error are higher in sub-groups.
