How is it that in the U.S.,surveys of 1,000 are accepted as representative of the entire country?

Question

I’ve noticed most U.S. polls query around 1,000 people and sometimes even less. Somehow that qualifies for headlines like “Americans say…” or “Most Americans…” How is it acceptable that 0.0002% of the population is accepted as representative?

Answer 1

A single person is dynamic and hard to predict. People in large groups on the other hand are pretty damn predictable. You don’t need to ask many to get a good idea of trends.
