A new Business Insider-SurveyMonkey Audience poll has found that Americans know shockingly little about the budget, federal deficits, and major top-line economic indicators.

We asked about 500 respondents to write in an estimate of several different statistics, including the U.S. deficit.

Does America realize that?

If someone answered the question in the rage of hundreds of billions or trillions, they're probably in the right ballpark, or at least county.
