THIS REPORT BY THE SERVICE D'ETUDES PENALES ET CRIMINOLOGIGUES(S.E.P.C.) GIVES SOME OF THE RESULTS OF A LARGER STUDY BASED ON THE HYPOTHESIS THAT THERE IS A CORRESPONDENCE BETWEEN SOCIO-ECONOMIC CONDITIONS AND PATTERNS OF CRIMINALITY. THE COMPARISONS AND CORRELATIONS ARE PRESENTED IN THE FORM OF MAPS, TABLES, AND GRAPHS. THE GEOGRAPHICAL UNITS USED IN THE ANALYSIS ARE THE DEPARTEMENTS (FRENCH JURISDICTIONS). THE STUDY FOUND THAT THE CATEGORIES OF OFFENSE COULD BE DIVIDED INTO TWO BASIC FUNCTIONAL GROUPS. THE FIRST GROUP INCLUDED TRAFFIC OFFENSES, VOLUNTARY OR INVOLUNTARY OFFENSES AGAINST PERSONS, AND VIOLENT OR PETTY OFFENSES AGAINST PROPERTY. THIS GROUP OF OFFENSES, WHICH THE STUDY CALLED 'TRADITIONAL', OCCURRED AT APPROXIMATELY THE SAME RATE IN ALL GEOGRAPHICAL AREAS. THE SECOND GROUP INCLUDED FRAUDS, MORAL OFFENSES, AND OFFENSES AGAINST THE STATE. THIS GROUP, OF OFFENSES, WHICH THE STUDY CALLED 'SPECIFIC', OCCURRED AT SIGNIFICANTLY DIFFERENT RATES IN DIFFERENT AREAS. FURTHERMORE, THIS DIFFERENCE BETWEEN THE TWO GROUPS INCREASED BETWEEN 1962 AND 1968. THE STUDY ALSO FOUND THAT THE RATE OF SPECIFIC OFFENSES CORRELATED WITH MORE HIGHLY DEVELOPED SOCIO-ECONOMIC CONDITIONS. --IN FRENCH
