Only about half of the violent crimes and a third of the property crimes that occur in the United States each year are reported to police. And most of the crimes that are reported don’t result in the arrest, charging and prosecution of a suspect, according to government statistics.

The 30 largest U.S. cities saw a double-digit increase in their murder rate in 2016.

The estimated number of violent crimes in the nation decreased 0.2 percent in 2014 when compared with 2013 data, according to FBI figures.

The FBI says the number of violent crimes reported to law enforcement last year dropped by 4.4 percent from 2012.

The FBI is reporting that hate crime incidents were slightly down last year.

The number of violent crimes, however, increased 0.7 percent in 2012, with an estimated 1,214,462 violent crimes. 

The first six months of 2012 showed a 1.9 percent increase in violent crime, and a 1.5 percent increase in property crime. 

The nation's estimated rate of both violent and property crime shot up last year after several years of decline.
