Data viz: King County city crime rates, 1985-2011

by Nathan Brown August 16th, 2012

The highest per capita crime rates among King County cities in 2011 were in Tukwila, SeaTac, Seattle, Auburn, Burien, Federal Way, and Kent. The lowest were in Duvall, Sammamish, Yarrow Point, Clyde Hill, Medina, Snoqualmie, and Black Diamond. That and much more is shown in the following original data visualization for Public Data Ferret, which displays total crime rate data for King County cities during the years 1985 through 2011. It was developed using a tool made by the software firm, Tableau, based in Seattle’s Fremont neighborhood.

Population is represented by the size of the bubble for each city. As depicted in the color legend below the map, localities with total crime rates below the average for all cities in King County in the given year are shaded in green; the darker the shade, the lower the rate. Similarly, localities with rates higher than the average for all cities in King County in the given year are shaded in red; the darker the shade, the higher the rate. Hover the cursor over any bubble to view additional information about that locality, including violent crime rate and property crime rate. Crime rates are expressed as incidences per thousand residents. The maps display data as reported by each city’s police department within King County by the Washington Association of Sheriffs and Police Chiefs. “Empty” or absent cells reflect missing source data.
