Nationwide polls generally require a larger base size due to the need for accuracy and the need for reliable subsorts across many geographical areas.
Typically, nationwide polls are subsorted into four geographic regions and are also examined by a large number of other demographic and psychographic factors.
As a result, we strongly suggest a base size of 1,000 for a nationwide poll and will not accept polling at a base size of any less than 500. Reports are typically 250-300 pages.
