Story highlights The FBI's latest batch of data show a 3.9% year-over-year increase in violent crime

The FBI noted that's still down over five-year and 10-year periods

(CNN) Last year saw an increase in violent crime -- including murder -- compared to 2014, according to new data released by the Federal Bureau of Investigation on Monday.

The annual findings showed an estimated 1,197,704 violent crimes, up 3.9% from 2014, while the murder rate spiked by 10.8% over the same span. Those crimes include "murder and nonnegligent manslaughter, rape, robbery, and aggravated assault," the FBI's website said.

But the report indicated that violent crime is still below 2006 and 2011 levels for 10-year and five-year comparisons.

The numbers are somewhat expected, reflecting both anecdotal and statistical evidence of an increase in violence since last October. That trend has been visible in several large cities, including Chicago, Baltimore and Washington. Other major cities such as New York and Los Angeles have not experienced the same.

Attorney General Loretta Lynch said the data show "we still have so much work to do," but stressed the overall numbers are down compared to several years ago.
