This week, the FBI estimated that the number of violent crimes decreased 5.5 percent from 2009 to 2010, including a 4.4 percent decrease in the number of murders. Because the U.S. population increased during the period, the figures imply that the total violent crime per capita rate and the murder rate decreased more than six percent and five percent, respectively. Based upon the preliminary data, it appears that violent crime fell to a 37-year low and murder fell to a 47-year low. The FBI will report final figures for 2010 later this year.
