How many respondents do I need?

This depends on your tolerance for the margin of error and your population size.

Typically, a poll conducted in a local geographical region will be 400-500 respondents, and typically, a poll conducted in a state-wide or national geographical region will be 1,000 to 1,500 respondents. Normally, this will provide for a margin of error of +- 5% or less.
