Homicides and Clearance Rates - 7 ACCORDING TO THE FEDERAL BUREAU OF INVESTIGATION'S (FBI) Annual Uniform Crime Reports (UCR) for 2005, the number of homicides in the United States increased by 4.8 percent compared to 2004-the largest single-year increase for homicides in 14 years. And, for June 2006 the trend continued, with preliminary UCR data showing that homicide increased by 0.3 percent, with a much larger increase of 6.7 percent in cities with populations of 1 million or more. While the number of homicides in the U.S. has fluctuated since the 1960s, the number of homicides being solved has decreased in that time.
