Areas covered include crime rates in developing and developed countries, socioeconomic indicators of crime, and criminal justice personnel. These data indicate that property crimes are the typical crimes of developed countries, while higher levels of crime and violence are found in developing countries. Also examined are survey response rates and patterns, police agency responsibilities and training, prosecutors' duties, judicial appointments, prison staff, and volunteers in corrections.
