Violent crime fell 5.5 percent and crimes against property dropped by 2.8 percent in the United States in 2010, compared to the figures for the previous year, the FBI announced Monday.

The Federal Bureau of Investigation calculated its statistics on the basis of information provided by 13,007 police departments nationwide.

In 2010, murder and non-negligent manslaughter fell by 4.4 percent, forcible rape by 4.2 percent, armed robbery by 9.5 percent and aggravated assault by 3.6 percent.

The FBI figures show a decline in the four categories of violent crime across all groups of cities, and cities with populations between 250,000 and half a million saw the greatest reduction in violent crime: 6.9 percent.

Violent crimes perpetrated in non-metropolitan counties fell by 6.4 percent and those committed in metropolitan counties declined by 6 percent.

Murder and non-negligent manslaughter dropped by 25.2 percent in cities with fewer than 10,000 residents, but in cities with populations between 250,000 and 500,000 these crimes increased by 3 percent.

All classifications of cities and counties last year registered a decline in forcible rape except those with populations between 500,000 and 1 million, where crimes of that kind increased 1.9 percent.

Among crimes against property, in 2010 there was a reduction in all categories: burglary, larceny-theft and vehicle theft.

The greatest reduction occurred in automotive vehicle theft with a 7.2 percent decline, followed by larceny-theft with a 2.8 percent drop and burglary, which experienced a 1.1 percent fall.
