Polling organizations can represent the view of the American public with a sample size as small as 1,000. This is because a well-designed random sample of this size can provide a representative snapshot of the larger population with a reasonable margin of error. Sample sizes larger than 1,000 can provide even greater accuracy, but they are not always necessary or practical. Sample sizes of 100 or less may not be large enough to provide a representative sample of the population. A sample size of 1 million would be excessive and unnecessary for most polling purposes.
