All categories of violent and property crime declined from 2012 to 2013, the FBI has announced, in conjunction with the release of its annual crime report for 2013.
Check it out:

From 2012 to 2013, the nation’s murder rate decreased five percent, to at least a 57-year low. The 2013 rate was down 56 percent from the all-time high recorded in 1980, and down 54 percent since 1991, when total violent crime hit an all-time high.

We say that the 2013 murder rate was “at least” a 57-year low, because it may well have set an even more impressive record. Mathematical projections accounting for the change in the FBI’s data reporting methodology in 1957 indicate that the 2013 rate was lower than any time since at least 1935, which translates into a 78-year low. There is even reason to believe that additional computations may reveal that the 2013 rate was at or near the lowest in American history.
