The number of crimes reported to police dropped again last year compared with 2010. Last year marked the fifth straight year of year-to-year improvement for the number of violent crimes reported to authorities. It was the ninth consecutive year of declines for property crimes, according to preliminary FBI data for 2011. The FBI says murder and non-negligent manslaughter, rape, robbery and aggravated assault all went down in 2011. Violent crime decreased in all four regions: 4.9 percent in the Midwest; 4.7 percent in the West; 4.5 percent in the South and 0.8 percent in the Northeast. There was, however, an increase in murder in the Midwest - 0.6 percent - and an 18.3 percent jump in murder in cities with populations of less than 10,000. In the property crime category, motor vehicle theft dropped 3.3 percent, and larceny-theft decreased 0.9 percent. However, burglary offenses increased 0.3 percent, rising 3.2 percent in the Northeast, 1.3 percent in the Midwest and 0.7 percent in the West. The preliminary data is based on information the FBI gathered from 14,009 law enforcement agencies around the United States.
