The American public, on average, believes NASA's budget has a much larger share of the federal budget than it actually does. A 1997 poll reported that Americans had an average estimate of 20% for NASA's share of the federal budget, far higher than the actual 0.5% to under 1% that has been maintained throughout the late '90s and first decade of the 2000s. It is estimated that most Americans spent less than $9 on NASA through personal income tax in 2009.
