This research overview presents data on juvenile arrests and arrest rates for serious violent and property crimes in Alaska known to police from 2002 to 2010. Figures presented, from the FBI's Uniform Crime Reporting (UCR) program, are for the eight serious offenses defined as Part I offenses: murder/non-negligent manslaughter, forcible rape, robbery, aggravated assault, burglary, larceny-theft, motor vehicle theft, and arson. Alaska figures for 2010 are compared with those for five other western U.S. states — Idaho, Montana, Oregon, Washington, and Wyoming.
