Chapter 2 – The Nature and Extent of Crime
Crime Patterns and Trends n n n Want to know How much crime is there? Is it increasing or decreasing? Who commits crime? Answers are used to formulate theories and develop policies to control crime
Methods of Measuring Crime Uniform Crime Reports Victim Surveys Self-Report Surveys
Uniform Crime Reports n n Best known source of aggregate criminal statistics 98% of the police departments in the US voluntarily participate in UCR Yearly FBI publication Started 1930
Uniform Crime Reports n n 2 types of data collected: 1) Offenses reported to the police Collect information on index crimes reported to the police Known as Index or Part I crimes
Uniform Crime Reports Violent Crime n Index Crimes n Criminal Homicide n Forcible Rape n Robbery n Aggravated assault n Burglary n Larceny/theft n Motor vehicle theft n Arson Non-violent Crime
Uniform Crime Reports n n n 2) Number and characteristics (age, gender, and race/ethnicity) of those arrested for all other crimes Known as non-index or Part II crimes On average, 20% of all reported index crimes are cleared by arrest, lower for many non-index crimes.
Uniform Crime Reports n n Problems with the UCR 1) On average approximately 50% of all index crimes are reported to the police n n 26% 50% 45% 57% of of thefts burglaries rapes robberies
Uniform Crime Reports n n 2) On average, 20% of all reported index crimes are cleared by arrest 3) State law definitions may be different than UCR definitions 4) Systematic errors in reporting 5) Deliberate alteration
Uniform Crime Reports • 6) Only the most serious crime is an “episode” • 7) Weak on “white collar” crime
The Future of the Uniform Crime Reports n n n National Incident-Based Reporting System (NIBRS) Maintained by the F. B. I. Twenty-two crime categories More information on each crime in each category Data compiled based on incidents, not arrests.
Victimization surveys n n n National Crime Victimization Survey-NCVS US Census Started in 1972 60, 000 households 120, 000 people over 12 years old Interviewed 2 times a year for 3 years
NCVS n n Ask about theft, burglary, robbery, assault, rape, and auto theft Used to estimate the national frequency of index crimes
Data provided by NCVS n n Victimizations Victims, offenders, crime event Reported loss & injury Whether crimes were reported
NCVS Number of Offenses 20, 106, 000 Total = 35, 145, 000 7, 359, 000 4, 635, 000 1, 433, 000 Theft* Assault Burglary Motor vehicle theft 944, 000 Robbery 311, 000 Rape/ Sexual assault *Includes 357, 000 “personal crimes” of purse snatching & pocket picking. Source: National Crime Victimization Survey. Criminal Victimization, 1997. Adapted from U. S. Department of Justice, Bureau of Justice Statistics (Washington, DC: U. S. Government Printing Office, December 1998), p. 3.
Advantages & Limitations of NCVS ADVANTAGES DISADVANTAGES 1) Best victimization data 1) Victim misinterpretation 2) Memories fade 3) Lying to interviewer 4) Telescoping – problems with recall 5) Expensive 2) “larger picture of crime”
Self-Report Surveys 4 4 4 Participants reveal information about their violations of the law Helps to get at “Dark Figure of Crime” Supplement and expand official data Can find out about the personality, attitudes, and behavior of criminals Accuracy for chronic offenders and drug abusers may be limited
Self Report Studies n n n Interviews mainly with juveniles Most youth engaged in delinquency (crime is universal Higher crime patterns than UCR and NCVS
Self-Report Surveys n n Strength of self-reports surveys is get more detailed information Weaknesses include n n Inaccuracy – are they telling the truth? Focus on trivial acts frequently
Current Crime Trends Current data from the Uniform Crime Reports and the National Crime Victim Surveys reveal a steady decrease in crime. Selfreported data reveals no discernable change in the rate.
Current Crime Trends n n Caution in interpreting UCR and other data Time frame is important Overall rate hides increases and decreases within crime categories Want disaggregated data n By offense, state/region, etc.
Explaining Crime Trends Some of the important critical factors that have been used to explain the puzzle of crime rate trends. n n n Age The economy Guns n n n Gangs Drugs Justice Policy
Correlates of Crime • Social class • Race • Gender • Age
Correlates of Crime – Social Class n Higher crime rates in lower class areas n n Rely on official statistics Concern over whether function of police practices or actual behavior patterns Crime is not just street crime Self-report studies indicate class-crime relationship doesn’t exist n Focus on trivial offenses
Correlates of Crime – Social Class n n n Why important? 1) If class-crime relationship then poverty and neighborhood deterioration related to crime 2) If not then factors experienced by all classes (poor family environment, peer pressure, school failure, free will) related to crime
Correlates of Crime – Age n n Some argue that age structure of society is the single most powerful influence on the crime rate 13 -17 year olds make up 6% of the population but 30% of index crime arrests
Correlates of Crime – Age n n Property crime arrests peak at age 16 Violent crime arrests peak at age 18
Correlates of Crime – Age n n Why does aging out occur? Cognitive changes in late teens n n n No longer need for immediate gratification Fear of punishment Adulthood brings powerful ties to conventional society
Correlates of Crime – Gender n Male crime rate higher than female Males commit more serious crimes n Recent view of female criminality n n n Socialization of females (supervised closely) Changing social and economic role of women
Correlates of Crime – Gender n n Crime more a function of economic inequality instead of female rights End of “chivalry hypothesis”
Correlates of Crime – Race/Ethnicity n n n Minorities involved in disproportionate % of crimes Blacks 12% of population, 44% of index violent crime arrests Reflection of police practices or true criminal participation?
Correlates of Crime – Race/Ethnicity n n n Causes of racial disparity in crime Differential treatment by police Subculture of violence Racism and discrimination affect personality and behavior Poverty/Urban problems Etc.
Knowledge drawn from UCR, NCVS, and Self Report Studies n Crime Trends n Characteristics of Crimes n Characteristics of offenders & victims n Correlates of Crime
The “Chronic 6%” After following a birth cohort of 9, 945 boys born in Philadelphia in 1945, Wolfgang and his associates found that 6% of the total sample were responsible for 51. 9% of all offenses.
The “Chronic 6%” n n Wolfgang findings 1) Small number of offenders commit a disproportionate amount of crime 2) Chronic offenders continue into adulthood 3) More violent as generations progress
