The congresses have taken place every 5 years starting in 1955. A seventh congress will take place in 1985. These meetings reflect expanding international cooperation and do not impose particular viewpoints on the handling of crime problems. Over the years their focus has shifted from treatment of offenders to the prevention of crime, the development of criminal justice standards, and the formulation of guiding principles. They have also reflected the view that crime is a socioeconomic and political phenomenon encompassing much more than traditional common crime. The abuse of power and the resulting increase in new forms of crime are now the most serious aspects of the growing crime problem. Increased professional staff for the United Nations congresses and increased use of the regional institutes would be desirable. The congresses should be renamed Congresses for the Prevention of Crime and Criminal Justice to reflect their contemporary goals.
