CRIME DATA OF FOUR REGIONS IN WHICH LARGE INDUSTRIAL PLANTS WERE BUILT IN FORMERLY RURAL AREAS WAS ANALYZED FOR THE PERIOD FROM 1958 TO 1974. FOUR STAGES OF INDUSTRIAL DEVELOPMENT WERE CONSIDERED: (1) PREPARATION, (2) CONSTRUCTION OF THE PLANT, (3) START OF PRODUCTION, AND (4) STABILIZATION. A SHARP TEMPORARY INCREASE IN CRIME (34 TO 92 PERCENT) WAS FOUND IN THREE AREAS. NO INCREASE IN CRIME WAS NOTED DURING THE FIRST STAGE, BUT DURING THE SECOND STAGE, BY A POPULATION MIGRATION, CRIME RATES ROSE. AFFECTED WERE MAINLY PROPERTY CRIMES AND RUFFIAN BEHAVIOR WHILE UNDER THE INFLUENCE OF ALCOHOL. HOWEVER, 80 PERCENT OF THE OFFENDERS WERE LOCAL INHABITANTS OF THE REGION, SO THAT CRIME WAS NOT CAUSED BY THE DEMOGRAPHIC CHANGES. THE LEVEL OF CRIME DECREASED DURING SUBSEQUENT STAGES. A RISE IN JUVENILE CRIME WAS NOTED 10 T0 15 YEARS AFTER THE BEGINNING OF INDUSTRIALIZATION. THIS IS ATTRIBUTED TO OUTMODED CHILDREARING TECHNIQUES OF PARENTS WHO CAME TO THE CITY FROM RURAL AREAS.
