Both the Newark and Camden areas are among the 25 most peaceful metro areas in the country, according to a report produced by the Institute for Economics and Peace in Washington, D.C.

The Camden area placed 14th on a list ranking 61 metro areas in the county, while Newark-Union was assigned the No. 24 spot. The Edison-New Brunswick area was named the second most peaceful area in the country, trailing only Cambridge-Newton-Framingham in Massachusetts, the report said.

The Metropolitan Peace Index is based on four factors: the homicide rate, violent crime rate, incarceration rate, and police presence.

The Seattle area took the third spot. The least peaceful area is metropolitan Detroit, followed by New Orleans, Nashville, Tenn. and Miami.

Among the report's conclusions is that the United State is more peaceful now than at any time in the past 20 years.
