Title: Chapter Two: Measuring Crime
1Chapter Two Measuring Crime Criminal Behavior
2Chapter Summary
- Chapter Two introduces the students to the
techniques used to collect data on crime in the
United States. The chapter covers the pros and
cons of official statistics, victimization survey
data, and self-reported data. - The second half of the chapter discusses the
financial cost of crime, and how that cost is
estimated. In the concluding section, the chapter
highlights some of the major theories used to
explain crime trends in the United States through
time.

trends.
5Categorizing and Measuring Crime and Criminal
Behavior
- When attempting to understand, predict, and
control any social problem, including the crime
problem, the first step is to determine its
extent. - Three categories of major crime data sources in
the United States - Official statistics
- Victimization survey data
- Self-reported data
6 The Uniform Crime Reports Counting Crime
Officially
- The primary source of official crime statistics
in the United States is the annual Uniform Crime
Reports (UCR) compiled by the Federal Bureau of
Investigation (FBI). - The UCR reports crimes known to the nations
police and sheriffs departments and the number
of arrests made by these agencies federal crimes
are not included - Participation in the UCR reporting program is
voluntary, and thus all agencies do not
participate.
7The Uniform Crime Reports Counting Crime
Officially
- The UCR separates crimes into two categories
Part I offenses (or Index crimes) and Part II
offenses. - Murder The willful (non-negligent) killing of
one human being by another. - Forcible rape The carnal knowledge of a female
forcibly and against her will.
8The Uniform Crime Reports Counting Crime
Officially
- Robbery The taking or attempted taking of
anything of value from the care, custody, or
control of a person or persons by force or threat
of force or violence and/or putting the victim in
fear. - Aggravated assault An unlawful attack by one
person upon another for the purpose of inflicting
severe or aggravated bodily injury.
9The Uniform Crime Reports Counting Crime
Officially
- Burglary The unlawful entry of a structure to
commit a felony or theft. - Larceny-Theft The unlawful taking, leading, or
riding away from the possession or constructive
possession of another. - Motor vehicle theft The theft or attempted theft
of a motor vehicle.
10The Uniform Crime Reports Counting Crime
Officially
- Arson Any willful or malicious burning or
attempting to burn, with or without intent to
defraud, a dwelling house, public building, motor
vehicle or aircraft, personal property of
another, etc.
11The Uniform Crime Reports Counting Crime
Officially
- Determining Crime Rates
- The rate of a given crime is the actual number of
reported crimes standardized by some unit of the
population - To obtain a crime rate we divide the number of
reported crimes in a state by its population, and
multiply the quotient by 100,000.
12The Uniform Crime Reports Counting Crime
Officially
- The FBIs famous crime clock provides estimates
of the relative frequency with which each Part I
Index crime (arson is omitted) is committed. - Part II offenses are treated as less serious
offenses and are recorded based on arrests made
rather than causes reported to the police. - Part II may not be true criminal offenses, or
if they are, may not be particularly serious.
13The Uniform Crime Reports Counting Crime
Officially
- Cleared Offenses-If a person is arrested and
charged for a Part I offense, the UCR records the
crime as cleared by arrest.. - A crime is also recorded as cleared by
exceptional means, or the police have identified
a suspect and have enough evidence to support
arrest, but he or she could not be taken into
custody immediately, or at all.

- Every 32.6 minutes One Murder
- Every 5.6 minutes One Forcible Rape
- Every 1.3 minutes One Robbery
- Every 36.9 seconds One Aggravated Assault
- Every 3.1 seconds One Property Crime
- Every 14.7 seconds One Burglary
- Every 4.5 seconds One Larceny-theft
- Every 25.5 seconds One Motor Vehicle Theft

Government Printing Office. Note The crime
clock should be viewed with care. The most
aggregate representation of UCR data, it conveys
the annual reported crime experience by showing a
relative frequency of occurrence of Part I
offenses. It should not be taken to imply a
regularity in the commission of crime. The crime
clock represents the annual ratio of crime to
fixed time intervals.
15Problems with the UCR
- The UCR data significantly under-represents the
actual number of criminal events in the United
States each year. - Drug offenses and federal crimes are not
included. - The voluntary nature of the UCR program means
that the crimes committed in the jurisdictions of
non-participating law enforcement agencies are
not included in the data. - Crime data may be falsified by police departments
for political reasons.
16The Uniform Crime Reports Counting Crime
Officially
- The UCR under-reports crimes that are know to the
police because of the FBIs hierarchy rule, which
requires police to report only the highest
offense committed in a multiple-single incident
to the FBI and to ignore others. - The most frequent criticism has been that these
data are too easily affected by discretionary
police policies to be considered reliable.

Survey Data

Justice Statistics.
21NIBRS The New and Improved UCR
- The National Incident-Based Reporting System
(NIBRS) began in 1982, and is designed for the
collection of more detailed and more
comprehensive crime statistics - NIBRS collects data on 46 Group A offenses and
11 Group B offenses - There is no hierarchy rule under the NIBRS system
22NIBRS The New and Improved UCR
- The NIBRS provides information about the
circumstances of the offense and about victim and
offender characteristics. - Although reliable, the NIBRS still generates
concern over the dark figure of crime, which
refers to all of the crimes committed that never
come to official attention.
23Problems with the NCVS
- Crimes such as drug dealing and all victimless
crimes are not revealed, as well as the serious
crime of murder. - Crimes committed against commercial
establishments are not included. - Victimization data do not have to meet any
stringent legal or evidentiary standards in order
to be reported as an offense.
24Problems with the NCVS
- Memory lapses, answering the way the respondent
believes the interviewer wants to hear,
forgetting an incident, embellishing an incident
may occur. - Over-reporting may occur.
25Areas of Agreement between the UCR and NCVS
- Both the UCR and NCVS agree on the demographics
of crime. - Males, the young, the poor, and African Americans
are more likely to be perpetrators and victims of
crime than are females, older persons, wealthier
persons, and persons of other racial or ethnic
categories. - Both agree on recent crime trends.
26Self-Reported Crime Surveys
- Self-reported surveys of criminal offending are a
way criminologists are able to collect data for
themselves without having to rely on governmental
sources. - These surveys involve asking people to disclose
their delinquent and criminal involvement on
anonymous questionnaires or face-to-face
interviews.
27Self-Reported Crime Surveys
- The greatest strength of self-report research is
that researchers can correlate a variety of
characteristics of respondents with their
admitted offenses that go beyond the demographics
of age, race, and gender. - Self-report crime measures provide largely
accurate information about some forms of
anti-social offending, and reveal that almost
everyone has committed some sot of illegal act
sometime in their life.
28Problems with Self-Reported Crime Surveys
- The great majority of self-reported studies
survey convenience samples of high school and
college students. - Self-report studies typically uncover only fairly
trivial antisocial acts such as fighting,
stealing items worth less than 5, smoking, and
truancy.
29Problems with Self-Reported Crime Surveys
- Even though most people are forthright in
revealing their peccadilloes, most people do not
have a serious criminal history, and those who do
have a distinct tendency to under-report their
crimes. - Reporting honesty varies across race/ethnicity
and gender
30The Dark Figure of Crime Revisited
- For official statistics, the dark figures are
highly concentrated at the non-serious end of the
crime seriousness spectrum. - Dark figures for victimization data are primarily
concentrated in the non-serious end of the
spectrum, although to a lesser degree than in the
case of official data. - Most of the dark figures in the case of
self-reports are concentrated in the upper end of
the seriousness continuum.

32What Can We Conclude about the Three Main
Measures of Crime in America?
- UCR data is probably the best single source of
data for studying serious crimes, especially
murder rates and circumstances. - For studying less serious types of crimes, either
victimization or self-report survey data are the
best - If the interest is in drug offenses, self-reports
are the preferable data source.
33The Financial Cost of Crime
- Most estimates of the annual financial cost of
crime focus on the costs of running the criminal
justice system, which includes the salaries and
benefits of the personnel, and the maintenance
costs buildings and equipment. These costs are
known as the direct costs of crime.
34The Financial Cost of Crime
- The indirect costs of crime include manner of
surveillance and security devices, protective
devices, and insurance costs, medical services,
and the productivity and taxes lost of
incarcerated individuals.
35Interpreting Crime Trends
- There is no single cause of crime or criminality,
there is no single cause that explains crime
trends - Possible reasons for crime rate fluctuations
since the 1960s - Poverty Changes in the poverty rate can be
accompanied by wither an increase or decrease in
the crime rate, depending on what years we begin
and end with and what other process are operating
at the same time.
36Interpreting Crime Trends
- Affluence The affluent society
- offers many targets for criminals to
- aim at, as well as more goods available
- to steal.
37Interpreting Crime Trends
- Moral Breakdown Societal Well-Being
-
- Many think that a breakdown in the
- general moral order that occurred in the
- tumultuous 1960s may be the
- explanation for the rise in crime
- through the early 1990s.
38Interpreting Crime Trends
- The Family Problems of the family, such as
divorce, can be expected to impact other areas of
society.
39Interpreting Crime Trends
- Deindustrialization The workplace transition has
impacted minorities and whites of low
socioeconomic backgrounds most severely resulting
in a lot of frustration and the hardening of
poverty.
40Interpreting Crime Trends
- The Prison Boom Advocates of get tough
policies credit the increased numbers of
offenders being imprisoned for the decrease in
crime. - The Baby-Boomer Bubble When the first cohort
of baby-boomers became teenagers in the early
1960s, there would be a rather dramatic increase
in crime.
41Interpreting Crime Trends
- Drug Market Stability Just as prohibition of the
manufacture and sale of alcohol in the 1920s and
1930s spawned large increases in violent crime as
violent gangs vied for control of the alcohol
market, the illicit drug market spawned huge
increases in the violent crime in the 1980s.
