For the first 6 months of 1984, the number of reported Index crimes declined by 4.1 percent compared to the comparable period in 1983. All counties showed an overall decrease. Property crimes decreased by 4.1 percent. All categories of property crime declined, led by an 11.6-percent decrease in motor vehicle theft. Burglaries were down 7 percent, and larceny-theft, the category with the most reported crimes, declined 2.2 percent. Violent crimes decreased 4.6 percent. Murders decreased by 46.7 percent, aggravated assaults by 6.8 percent, and robberies by 3.5 percent. While rapes increased by 6.5 percent, this was still below the 1982 level. A comparison of murder victim characteristics for 1978-83 indicates that in 1983, the number of male victims decreased, while female victims increased relative to the 5-year average. Similarly, increases in 1983 were found in the proportion of Caucasian victims, victims under 15 years of age, and victims 25 to 29 years old. Finally, an examination of the relationship between population density and crime rates for the Pacific area and the Northeast fails to show any consistent relationships.
