In many countries all over the world, statistics show continuous rise in crime rates and general inability to control this trend. A preliminary comparison study, based on a questionnaire to which 35 Western and Third World countries responded, showed an increase in all types of offenses except in crimes of political motivation and illegal possession of firearms during 1965-1975. Significant increases appeared in juvenile, property, violent, drug, and white collar crime. The general trend indicated a greater increase for most offenses in both the highly developed and less developed countries than in those of intermediate development. It was recommended that the United Nations and the international community help further the exchange of experts and information through conferences and seminars, and establish centers for criminological research and correctional training. Statistical data and footnotes are included.
