Safety >> Crime >> Index Crime >> Trends by Region

From 2007 to 2011, crime rates declined in all but unincorporated areas and North Region cities, which had relatively low rates in 2007.

Crime diminishes the health of our communities through fear, erosion of community cohesion, diversion of public resources, property damage, injury, incarceration, and death. Regional city rates were compiled from city police department data. The crime rate for unincorporated areas is included in the King County rate. 

The FBI Index Crime Rate, expressed as number of crimes per 100,000 persons, tracks serious crime in the U.S.  The Index includes four major violent crimes (homicide, rape, robbery, and aggravated assault) and four major property crimes (burglary, larceny/theft, motor vehicle theft, and arson).

  • The index crime rate in King County decreased significantly from a high of 9,270 per 100,000 in 1987 to 4,419 per 100,000 in 2011. For comparison, the 2011 index crime rate in Washington State was 3,831 per 100,000 (data not shown).
  • Index crime rates declined significantly between 1997 and 2011 in all city-defined regions, Seattle, and unincorporated King County. 
  • Between 2007 and 2011, index crime rates dropped in all but unincorporated areas and North Region cities, which had relatively low rates in 2007.
