There is half as much crime in the US right now as there was about 25 years ago. Both violent and property crime have declined pretty steadily since the early 1990s.
But Americans are more concerned about crime now than they have been since 2001.
That's because Americans keep thinking that crime rates are going up. At any given time, between half and three-quarters of them will say that there's more crime in America than there was last year.
