Violent crime may be on a historic decline in New York City this year, but a recent study claims that it's on the rise across the U.S. According to the National Crime Victimization Survey, it has increased for the second year in a row, jumping by 15 percent between 2011 and 2012. 

However, it should be noted that this data often reflects crimes not reported to police. When only considering crimes reported, the study did not reflect much of a difference between the two years. Also, keep in mind that homicides are not included in the survey because the data was taken from victims. Furthermore, the report revealed that crime rates across the board have been dropping since 1993, aside from a noticeable increase in 2006.
