Alcohol and Crime

Foreword

The extensive and far-reaching

impacts of alcohol abuse on crime and

public safety are only now achieving

widespread public policy attention.

This report was prepared to provide

statistical information as background

for the Assistant Attorney General’s

1998 National Symposium on Alcohol

Abuse and Crime, which will address

many of these policy issues and

discuss approaches that may help

alleviate these problems.

Based on this compilation and new

analysis of data on alcohol and crime,

we know that nearly 4 in 10 violent

victimizations involve use of alcohol,

about 4 in 10 fatal motor vehicle

accidents are alcohol-involved; and

about 4 in 10 offenders, regardless of

whether they are on probation, in local

jail, or in State prison, self-report that

they were using alcohol at the time of

the offense.

There are, however, a number of

positive indicators that alcohol-related

crime is generally decreasing and that

most of those in need of treatment are

receiving it. Violence between current

and former spouses, boyfriends, and

girlfriends is especially likely to

involve alcohol abuse, and all forms of

violence against intimates, including

homicide, have been declining in

recent years. In addition, rates of

arrest for DUI have declined by 24%

since 1990. During the last 10 years,

the number of highway fatalities attrib-

utable to alcohol-related accidents has

dropped by about 7,000 annually, a

29% decrease.

This report uses a wide variety of

sources, including statistical series

maintained by the Bureau of Justice

Statistics (BJS), the Federal Bureau of

Investigation, the National Highway

Traffic Safety Administration, and the

Bureau of Transportation Statistics.

We are grateful for the cooperation of

these agencies and also want to thank

the many respondents to our surveys

throughout the country.

We anticipate that more on the issue

of alcohol and crime will be available

in the near future as new data collec-

tions by BJS, including the 1997

Survey of Inmates of State and

Federal Correctional Facilities, are

analyzed. BJS has incorporated new

questions into its surveys which will

enable a more in-depth understanding

of the alcohol use and abuse

backgrounds of offenders and the

nature of the treatment they receive

while incarcerated.

Highlights

This report provides the most compre-

hensive analysis of statistical data on

alcohol and crime published to date by

BJS.

Sources of information include the

BJS National Crime Victimization

Survey (NCVS), BJS self-report

surveys of correctional populations,

and the periodic BJS censuses of

Federal, State, and local corrections

facilities. In addition, arrest data from

the FBI’s Uniform Crime Reporting

Program and the most recent data

available from the FBI’s National

Incident-Based Reporting Program are

used to supplement national survey

data.

Finally, the report includes new analy-

ses from the National Highway Traffic

Safety Administration’s Fatal Accident

Reporting System (FARS), a database

providing detail on more than 2.1

million fatal motor vehicle accidents

that occurred over the last two

decades. The study provides the first-

ever estimates of the level of intoxica-

tion among drinking offenders at the

time of the commission of the offense

for which they had been convicted.

The role of alcohol in crime

victimization

About 3 million violent crimes occur

each year in which victims perceive

the offender to have been drinking at

the time of the offense. Among those

victims who provided information

about the offender’s use of alcohol,

about 35% of the victimizations

involved

an offender who had been drinking.

About two-thirds of the alcohol-

involved crimes were characterized as

simple assaults.

Two-thirds of victims who suffered

violence by an intimate (a current or

former spouse, boyfriend, or girlfriend)

reported that alcohol had been a

factor. Among spouse victims, 3 out

of 4 incidents were reported to have

involved an offender who had been

drinking. By contrast, an estimated

31% of stranger victimizations where

the victim could determine the

absence or presence of alcohol were

perceived to be alcohol-related.

For about 1 in 5 violent victimiza-

tions involving perceived alcohol use

by the offender, victims also reported

they believed the offender to have

been using drugs as well.

Data for 1995 from the National

Incident-Based Reporting System

(NIBRS) of the FBI indicate that about

half the incidents described by the

investigating officer as alcohol-related

were between offenders and victims

who were intimates.

NIBRS data show that about 7 out

of 10 alcohol-involved incidents of

violence occurred in a residence; the

hour beginning at 11 p.m. was the

most frequent time of occurrence; and

about 2 in 10 incidents involved the

use of a weapon other than hands,

fists, or feet.

Alcohol and Crime

DUI/DWI: Arrests and fatal

accidents

In 1996, local law enforcement

agencies nationwide made an

estimated 1,467,300 arrests for driving

under the influence (DUI). Arrests for

DUI peaked in 1983 when there were

1.9 million arrests. Compared to

1983, the per capita rate of arrest for

DUI in 1996 was 34% lower.

Declines in DUI arrest rates have

occurred for every age group. Of

particular note is the decrease in DUI

arrest rates for those under the age of

21 compared to their rates of DUI

arrest in the early 1980's when States

had not adopted a uniform drinking

age. In 1980 persons between 16

and 20 years old accounted for 10%

of licensed drivers but 15% of DUI

arrestees. In 1996, this age group

accounted for 7% of drivers and 8%

of DUI arrestees.

In 1996 there were 17,126 alcohol-

related traffic fatalitiesaccounting for

40.9% of all traffic fatalities during the

year. This is a 29% reduction from

the more than 24,000 fatalities

recorded 10 years earlier when alcohol

was involved in 52% of the fatalities.

An estimated 32% of fatal accidents

involved an intoxicated driver or

pedestrian (the majority are drivers,

however) with a blood alcohol concen-

tration, or BAC, of at least 0.10 grams

of alcohol per deciliter of blood, the

most commonly used definition of

intoxication.

Over the last decade rates of intoxi-

cation in fatal accidents have declined

across every age group. In 1986,

there was about 1 driver involved in a

fatal accident in which he/she was

intoxicated for every 10,500 drivers; in

1996, the rate translates into about 1

intoxicated driver in a fatal accident

for every 17,200 licensed drivers.

Among drinking drivers whose BAC

at the time of the accident was known,

84% had a BAC of at least 0.08 g/dl

and 78% had a BAC of 0.10 g/dl or

higher.

The average BAC among drinking

drivers in fatal accidents was 0.16

g/dl. There was a strong relationship

between average BAC among drinking

drivers in fatal accidents and prior

driving record consistently, those

with prior suspensions, invalid

licenses, and prior driving while intoxi-

cated (DWI) convictions reflected the

highest BAC’s at the time of the crash.

Among drivers in fatal accidents who

had at least two prior DWI convictions,

the average BAC was 0.21 g/dl, the

highest of any group.

Use of alcohol by convicted

offenders

Among the 5.3 million convicted

offenders under the jurisdiction of

corrections agencies in 1996, nearly 2

million, or about 36%, were estimated

to have been drinking at the time of

the offense. The vast majority, about

1.5 million, of these alcohol-involved

offenders were sentenced to supervi-

sion in the community: 1.3 million on

probation and more than 200,000 on

parole.

There was some variation in the

percentage of offenders who had been

using alcohol at the time of the

Alcohol and Crime

Revised 04/28/98 th

40% of both jail inmates and proba-

tioners, 32% of State prisoners, and

29% of parolees.

Alcohol use at the time of the

offense was commonly found among

those convicted of public-order

crimes, a type of offense most highly

represented among those on probation

and in jail. Among violent offenders,

41% of probationers, 41% of those in

local jails, 38% of those in State

prisons, and 20% of those in Federal

prisons were estimated to have been

drinking when they committed the

crime.

Based upon self-reports of what

offenders were drinking and for how

long, it is estimated that the average

BAC level at the time of the crime

was:

Proba- Jail State

All offenders .16 .19 .27

Violent .18 .20 .28

Property .24 .22 .30

Drugs .14 .15 .19

Public-order* .14 .19 .23

*Includes offenses like driving while intoxicated,

weapons offenses, and commercial vice.

An estimated 62% of probationers

drinking at the time of the offense and

among daily drinkers 65% of

convicted jail inmates and less than

50% of State prisoners reported ever

participating in an alcohol treatment

program.

Alcohol and health issues

An analysis of alcohol dependence

among trauma center patients found

that the prevalence of alcoholism was

substantially higher among vehicular

crash victims and other trauma

patients than among the equivalent

general population group. More than

half of trauma patients with a positive

BAC at the time of the trauma were

diagnosed as alcoholics, and nearly

1 in 7 patients who were not drinking

at the time of the trauma were

diagnosed as alcohol-dependent.

Sources of data on alcohol

and crime

National Crime Victimization Survey

The National Crime Victimization Survey

(NCVS) is one of two statistical series

maintained by the Department of Justice

to learn about the extent to which crime is

occurring. The NCVS, which gathers

data on criminal victimization from a

national sample of household respon-

dents, provides annual estimates of

crimes experienced by the public without

regard to whether a law enforcement

agency was called about the crime. Initi-

ated

in 1972, the NCVS was designed to

complement what is known about crimes

reported to local law enforcement

agencies under the FBI's annual compila-

tion known as the Uniform Crime Report-

ing Program (UCR).

The NCVS gathers information about

crime and its consequences from a

nationally representative sample of U.S.

residents age 12 or older about any

crimes they may have experienced. For

personal contact crimes the survey deter-

mines who the perpetrator was.

In the latter half of the 1980's, the Bureau

of Justice Statistics (BJS), together with

the Committee on Law and Justice of the

American Statistical Association, sought

to improve the NCVS components to

enhance the measurement of crimes

including rape, sexual assault, and

intimate and family violence. The new

questions and revised procedures were

phased in from January 1992 through

June 1993 in half the sampled house-

holds. Since July 1993 the redesigned

methods have been used for the entire

national sample. The NCVS asks victims

of violence directly about their percep-

tions of alcohol and drug use by the

offender.

Uniform Crime Reporting Program

The Uniform Crime Reporting Program

(UCR) of the FBI provides another oppor-

tunity to examine the issue of alcohol-

involved arrests. The summary-based

component of the UCR, launched 70

years ago, gathers aggregate data on

eight categories of crime from law

enforcement agencies nationwide. While

the summary UCR does provide detailed

information on those arrested for driving

while under the influence, it does not

provide any information necessary to

identify violent crimes or arrests involving

alcohol. Such data are available,

however, from the incident-based compo-

nent of the UCR, the National Incident-

Based Reporting Program (NIBRS).

National Incident-Based Reporting

Program

NIBRS represents the next generation of

crime data from law enforcement

agencies. Rather than being restricted to

a group of 8 Index crimes that the

summary-based program uses, NIBRS

obtains information on 57 types of crimes.

The information collected on each violent

crime incident includes victim-offender

demographics, victim-offender relation-

ship, time and place of occurrence,

weapon use, and victim injuries. An

important contribution of NIBRS is that

investigating officers are asked to record

their perception of whether alcohol was a

factor in the incident. As of the end of

1997, jurisdictions certified by the FBI as

viii

Alcohol and Crime

capable of reporting incident-based

data in the required format account for

just over 7% of the U.S. population

(about 19 million Americans) and just

over 6% of all Index crimes (murders,

rapes, robberies, aggravated assaults,

burglaries, larcenies, and motor

vehicle thefts).

In those States with certified NIBRS

systems, about 50% of the population

is now covered by NIBRS reporting to

the FBI. BJS is currently funding

preliminary studies of NIBRS data and

their utility for improving our knowl-

edge of violence with special regard

for such concerns as intimate

violence, family violence, and domes-

tic violence and the role alcohol may

play in these kinds of police-reported

incidents.

Surveys of probationers, jail and

prison inmates

BJS also conducts national surveys of

persons under probation supervision

and those confined in local jails and

State and Federal prisons. These

nationally representative surveys are

the principal source of information on

those serving time following a convic-

tion: their backgrounds, their prior

criminal histories, and the circum-

stances surrounding the offense for

which they had been incarcerated.

Both jail and prison surveys obtain

from violent offenders details about

the offender's relationship to the

victim and how the crime was carried

out. All three surveys incorporate

detailed questions regarding alcohol

use and abuse both before the crime

and at the time the crime was commit-

ted. In addition, a number of

questions are devoted to treatment

and the types of treatments received.

Censuses of prisons and jails

BJS carries out facility-level data

collection among each of the 1,500

State and Federal prisons and the

3,300 local jails. These statistical

series gather detailed information on

the operations of each facility, includ-

ing capacity, staffing, programs, court

orders, and special functions or

services provided to inmates. Facili-

ties are queried about their treatment

programs and the extent of inmate

participation.

Fatal Accident Reporting System

Since 1975, the National Highway

Traffic Safety Administration of the

U.S. Department of Transportation

has maintained the annual Fatal

Accident Reporting System (FARS)

which obtains accident-level data on

each motor vehicle crash involving a

fatality. FARS uses State agencies

under contract to complete a standard-

ized form on each fatal accident which

covers weather and road conditions,

vehicle type, number of passengers

and fatalities, the manner of the crash,

whether there was a drinking or drug-

using driver involved, and specific

measurement of blood alcohol

concentration or BAC (grams of

alcohol per deciliter of blood).

Alcohol and Crime

Measuring the extent to which

alcohol is involved in crime

Estimates from the National Crime

Victimization Survey indicate that

victims of about 3 million violent

crimes each year, or about a quarter

of all violent crimes, perceived the

offenders to have been drinking.

Among victims of violence who were

certain that they could tell whether or

not an offender had been drinking,

about 35% of the violent victimizations

were believed to have involved an

assailant who had been drinking.

Household surve

s reveal that alcohol

use is common amon

most U.S.

residents. An estimated 8 in 10

persons a

ed 12 or older has used

alcohol at some time in their lives and

half describe themselves as current

users. Prevalence of use, however, is

e-sensitive since all States have,

since 1983, revised the le

al a

About 1 in 18 persons age 18 or older

describe themselves as consuming

two or more drinks per day

but

national estimates of annual per capita

consumption of alcoholic beverages

have dropped about 10% since 1990.

Even with this decline, aggregate

consumption translates into about one

drink per day for every resident.

In 1995 the Substance Abuse and

Mental Health Services Administration

conducted a survey of all known facili-

ties providing alcoholism treatment in

the United States. The survey

revealed that there were nearly

800,000 clients receiving services who

were considered to have an alcohol

problem. Almost certainly the number

of clients participating in such

programs would represent a substan-

tial underestimate of the size of the

total population for whom alcohol

abuse is a significant problem.

A variety of ways exist to estimate the

extent to which alcohol may be a

factor in crime. A significant caveat is

that most alcohol consumption does

not result in crime: the vast majority of

those who consume alcohol do not

engage in criminal behavior.

However, since nonoffending behavior

is not typically measured, there is little

statistical information upon which to

base any estimate of the likelihood of

committing a criminal act when

In 1993 the National Research Council's

Panel on the Understanding and Control

of Violent Behavior (Albert J. Reiss and

Jeffrey A. Roth, editors,

Understanding

and Preventing Violence,

Washington,

D.C.: National Academy Press, 1993,

pages 184-5) concluded, after an

exhaustive review of the literature that

existing prevalence research was not

sufficient to show that alcohol use or

intoxication increases the general risk of

violence. However, the panel did

observe that many studies had

documented offender use of alcohol

preceding the offense and that offender

populations usually were found to

contain heavy or problem drinkers.

Victims’ perceptions of alcohol use

by offenders

On average each year from 1992 to

1995, there were an estimated 11.1

million violent victimizations of residents

age 12 or older (figure 1). Victims of

violence were asked to describe whether

they perceived the offender to have

been drinking or using drugs.

Victims indicate that for about 7.7

million violent victimizations, about 70%

of all violent victimizations, they are able

to distinguish whether or not alcohol or

drug use by the offender was a factor.

In about 30% of violent victimizations,

the victim does not know whether the

offender had been using drugs or

alcohol.

Figure 1

Based on victim perceptions, about

2.7 million violent crimes occur each

year in which victims are certain that

the offender had been drinking. For

about 1 in 5 of these violent victimiza-

tions involving alcohol use by the

offender, victims believed the offender

was also using drugs at the time of the

offense (figure 2).

For those violent victimiza-

tions in which the victims

indicated that they were able to

report whether alcohol or drugs

had been used by the offender,

about 56% reported no use of

either substance and 37%

believed the offender was using

alcohol or alcohol in combina-

tion with drugs (figure 3).

Among victims who were able

to distinguish alcohol or drug

use by the offender, the victim-

offender relationship was an

important factor in whether the

victim reported alcohol

involvement:

Victim perceptions of the offender’s

use of drugs or alcohol also varies by

type of crime (figure 4).

Based on victim reports, on average

each year about 183,000 rapes and

sexual assaults involve alcohol use by

the offender, as do just over 197,000

robberies, about 661,000 aggravated

assaults, and nearly 1.7 million simple

Combined use of drugs and alcohol

accounted for 18% of the alcohol-

of the alcohol-involved robberies, 24% of

the aggravated assaults in which the

Drinking offenders committed over a third of the rapes or sexual

When the victim of violence

perceived that the offender was using

only alcohol at the time of the offense,

nearly two-thirds of the victimizations

were reported to have been simple

assault (figure 5). Robbery accounted

for about 6% of the violent victimiza-

tions involving a drinking offender but

19% of the incidents where the

offender was perceived to have been

using drugs.

Victim perceptions of offender use

of alcohol translate into an estimated

457,000 alcohol-involved violent

victimizations between victims and

offenders who share an intimate

relationship. Drinking offenders were

also responsible for about 118,000

incidents of violence between family

members (excluding spouses), an

estimated 744,000 violent incidents

between acquaintances, and about

1,360,000 incidents of violence

committed against a stranger

Alcohol and Crime

Beginning in 1995, BJS modified its

victimization survey to determine if a

sampled household is on a college

campus and if any household

members are college students. With

this more precise information, it has

become possible to learn more about

the victimization experience of

college students, both those who live

on campus and those who live off

campus.

College students reported about

463,000 violent victimizations in 1995

in which alcohol use by the offender

was a factor. An estimated 22% of

the alcohol-involved incidents were

perceived to have also involved

offender drug use. An estimated 90%

of the alcohol-involved violent victimi-

zations affecting college students

occurred off campus.

Among the 15.4 million college

students in 1995, about 1.5 million

experienced a violent crime.

About 87% of the violent crimes

sustained by college students

occurred off campus.

Overall, about 24% of the victims

of violence reported the offender

was using alcohol at the time of the

offense; about 4% described offender

drug use; and about 8% said that the

offender was using both drugs and

alcohol or that they could not tell

which.

Just over 43% of the victims of

violence were certain no drugs or

alcohol had been involved in the

offense.

Just over 20% did not know whether

the offender was using

either drugs or alcohol.

Per capita arrest rates for liquor law

violations are highest at public 4-year

colleges. See

Incident-based data on alcohol

and violent crime

The National Incident-Based Reporting

System (NIBRS) represents the next

generation of crime data from law

enforcement agencies. It is designed to

replace the nearly 70-year-old summary

Uniform Crime Reporting Program of the

FBI that compiles aggregate data on

eight crimes. NIBRS utilizes information

from individual crime reports recorded

by police officers at the time of the

incident. Rather than relying upon a

group of

8 Index offenses to convey the overall

crime situation, NIBRS collects informa-

tion on 57 types of crimes.

In addition, NIBRS provides the opportu-

nity to analyze a wide array of contingen-

cies of crime: who the victim was, the

relationship of the victim to the offender,

age of both victim and offender, where

and when the incident occurred, whether

alcohol may have been involved in the

offense, and the consequences of the

crime such as injuries and property loss.

A significant benefit of NIBRS is that the

report of the incident asks the investigat-

ing officer to indicate suspected alcohol

use by the offender.

Incident-based data on alcohol-involved

violence, from jurisdictions which

maintained such records of crime in

1995, provide details on such violence

not available from most law enforce-

ment agencies:

About half of the incidents of alcohol-

related violence recorded in the NIBRS

1995 dataset involved offenders and

victims who were intimates current or

former spouses, boyfriends or girlfriends

(figure 9).

About half of all violent incidents in which alcohol was present

and for which the police completed an incident report in 1995

involved victims and offenders in an intimate relationship,

including current and former spouses, boyfriends, and girlfriends.

Data for 1995 were obtained from law

enforcement agencies in nine States. The

violent offenses utilized in this analysis

included murder and nonnegligent

manslaughter, aggravated assault, simple

assault, and intimidation. Coverage for

these data is estimated to be about 2% of

murders in the United States, 4% of

reported aggravated assaults, and an

unknown percentage of simple assault and

intimidation offenses.

Figure 9

In just over 6% of the incidents of

alcohol-related violence, victims were

children under the age of 18 (figure

10). About 9% of the offenders who

were suspected of having been drink-

ing in violent incidents were under the

legal drinking age of 21.

About 7 out of 10 alcohol-involved

violent incidents occurred in a

residence; 1 in 10 occurred in a bar

or restaurant.

The largest number of violent

incidents involving alcohol use by the

offender were found to occur in the

hour beginning at 11 p.m.; the fewest

incidents occurred at 9 a.m. (figure

11).

DUI/DWI: Arrests and fatal

accidents

Driving while under the influence of

alcohol (DUI), which also includes

driving while under the influence of

drugs and driving while intoxicated

(DWI) represent the most common

reasons for arrests by the police. In

1996 DUI accounted for 1 in 10 arrests

for all crimes nationwide, an estimated

1,467,300 arrests. That same year,

an estimated 10,000 intoxicated

drivers were involved in fatal motor

vehicle accidents resulting in about

13,400 deaths.

The number of DUI arrests has

been declining:

In 1983, the highest recorded year

for DUI arrests in the last 30

years, local law enforcement

agencies reported 1,921,100

arrests for DUI from a popula-

tion of 154.4 million licensed

drivers, about 1 arrest for

every 80 licensed drivers.

In 1996 there were 1,467,300

arrests for DUI (including

persons under age 16) with

a licensed driver population

numbering 179.5 million, a

rate of 1 arrest for every

122 licensed drivers.

This represents a 34% reduction in the

per capita rate of DUI arrest nation-

wide over the period.

Alcohol and Crime

Figure 14

The National Highway Traffic Safety

Administration defines intoxicated drivers

as those with a blood alcohol concentra-

tion (BAC) of 0.10 grams of alcohol per

deciliter of blood or higher, the legal

measure of intoxication in most States.

Compared to their share of

licensed drivers, DUI arrestees

are overrepresented at each age

from 18 through 44.

Persons under the legal drinking age

of 21 account for about 8% of DUI

arrestees. About 7% of licensed

drivers are between the ages 21

and 24, but this age group accounts

for nearly 15% of

DUI arrests. By

contrast, those age 50 or older

account for a third of all drivers

but 9% of DUI arrestees.

Declines in DUI arrest rates have

occurred for every category of age

(figure 15). The age group with the

highest per capita rate of arrest for DUI,

21-year-olds, had a rate of 1 arrest for

every 42 drivers in 1990 which dropped

to 1 arrest for every 56 drivers in 1996

a 24% decrease.

The largest decrease in DUI arrest

rates since 1990 has occurred among

those age 25 to 29 (-31%) while arrest

rates have declined less than 10%

among persons age 16 and between

ages 35 and 44.

From the early to mid-1970's, States

lowered the minimum age for the

purchase or sale of alcoholic beverages.

Between 1970 and 1973, 24

States reduced the minimum age, and

by 1983, the peak year for DUI arrests,

33 States had a minimum age below 21.

As a result of changes in Federal

highway funds legislation, all States

raised the minimum age to 21. In 1980

persons under age 21 accounted for 10%

of licensed drivers but 15% of those

arrested for DUI, a 50% overrepresenta-

tion for drivers of this age. By contrast,

in 1996, persons under age 21

accounted for 7% of drivers and 8% of

arrestees for DUI, a substantially

reduced disparity compared to 1980.

The number of arrests for DUI per 1,000 licensed drivers

dropped 24% from 1990 to 1996.

The decline in arrest rates occurred for every age category,

Figure 15

The National Highway Traffic Safety

Administration (NHTSA) of the U.S.

Department of Transportation

estimates that in 1996, there were

17,126 alcohol-related fatalities

accounting for 40.9% of all traffic

fatalities during the year.

This repre-

sents a 29% reduction from the 24,045

alcohol-related fatalities in 1986, a

year in which alcohol-related crashes

accounted for 52% of the fatalities.

NHTSA also estimates that during

1996 about 7% of all crashes (both

fatal and nonfatal) were alcohol-

related and more than 321,000

persons were injured in such crashes.

While nearly 41% of traffic fatalities

in 1996 were alcohol-related, an

estimated 32% involved an intoxicated

driver or pedestrian (BAC=0.10 g/dl or

higher) a total of 13,395 fatalities.

Among these fatalities, about 70%

were themselves intoxicated. In 1996

local law enforcement authorities

carried out 140 arrests for DUI per

intoxicated driver involved in a fatal

crash.

Rates of intoxication among drivers

in fatal accidents have declined for

every age group over the last decade.

In 1986 an estimated 26% of drivers

had a BAC of at least 0.10 g/dl while

in 1996 about 19% were estimated to

have had a BAC at this level.

Examining BAC factors

Knowledge of the level of intoxication

of drivers in fatal accidents is derived

from the Fatal Accident Reporting

System (FARS) which gathers data on

a wide variety of issues relating to

fatal accidents, including driver,

vehicle, and environmental factors

associated with the crash. Initiated in

1975 by the National Highway Traffic

Safety Administration, data on fatal

vehicle accidents are compiled by

State officials from police reports, files

of State vehicle registration and

drivers’ licenses, death certificates,

hospital records, and other sources

and submitted under the FARS report-

ing program. Crashes occurring on

public roads in which a vehicle

passenger or nonpassenger (such as a

pedestrian or cyclist) dies within 30

days are included.

BAC levels of drivers or pedestrians

in fatal accidents may be measured

in a variety of ways using testing

methods which examine samples of

blood, breath, urine, saliva, or other

analyses of body tissue. Given that

BAC declines over time (BAC levels

decrease by about 0.015 g/dl per

hour), measured BAC levels among

surviving drivers in fatal accidents

would be somewhat less than the

actual BAC at the time of the crash.

FARS data on BAC for crashes

occurring in 1994 indicate that such

information is available for a third of

fatal accidents. However, BAC test

results are available for about 60% of

the drivers in fatal accidents who were

identified, presumably by police

officers or others, as having been

drinking drivers.

Among those crashes in which

persons were tested for BAC, an

estimated 59% were found to have a

BAC of zero and 41% had a positive

BAC of .01 g/dl or higher (figure 17).

BAC data indicating alcohol

consumption by a driver

involved in the accident are

available for nearly a quarter

million drivers in crashes in

which a death occurred.

Among these drinking drivers,

about 3 out of 4 had a BAC of

at least 0.10 g/dl and just

under a third were about twice

that level 0.20 g/dl or higher

(figure 21).

About 4 in 10 drivers in fatal accidents

with a drinking driver age 30 or older

had a BAC level above 0.20.

The average BAC among drinking

drivers in fatal accidents in 1994 was

0.16 g/dl (figure 20).

In fatal motor vehicle accidents

The highest average BAC among

drinking drivers was found for those

from age 40 to 44 (0.19 g/dl).

Just under 12% of drinking drivers

were known to have had prior

convictions for DWI.

The average level of intoxication was

about 25% higher for these repeat

offenders than among those who had

no reported prior DWI convictions.

The greater the number of prior license

suspensions and DWI convictions, the

higher the average BAC among drinking

drivers involved in fatal accidents (figure

23). Those with two prior DWI convic-

tions had an average BAC which was

10% higher than those with one prior

conviction and 33% higher than those

with no prior convictions.

There was substantial variation in

driving background among those at

different levels of intoxication (figure 24).

Those with the highest blood alcohol

concentrations, 0.30g/dl, were about 4

times as likely as those not drinking to

have had no valid license at the time of

the crash and about 7 times as likely to

have had prior DWI convictions. At each

intoxication level shown, the driving

record of the fatal accident driver

worsened.

BAC records of drivers in fatal accidents show that the levels

of intoxication at the time of the accident vary with the driving record.

Among drivers in fatal accidents, the highest average BAC level, 0.21,

or more than twice the legally defined level of intoxication in most States,

was found for those with 2 or more prior DWI convictions.

Use of alcohol by convicted

offenders

More than 36% of the 5.3 million

convicted adult offenders under the juris-

diction of probation authorities, jails,

prisons, or parole agencies in 1996 had

been drinking at the time of the offenses

for which they had been convicted. This

translates into just under 2 million

convicted offenders nationwide on an

average day

1.3 million on probation,

85,000 in local jails, 360,000 in State and

Federal prisons, and more than 200,000

under parole supervision

for whom

alcohol use was a factor in their crime

(figure 25).

BJS periodically conducts surveys

among the Nation’s offender population

in order to learn more about their

backgrounds. Representative samples

of probationers and those in local jails

and State and Federal prisons are inter-

viewed about their criminal histories,

family backgrounds, and many elements

of the current offense. Among the topics

of interest is their experience with

alcohol, both in the past and at the time

of the crime. These data represent

detailed information not typically avail-

able from official records and provide the

only uniform national description of

offender use of alcohol.

Note: The prevalence of alcohol use at the time of offense for parolees was estimated

by applying the known percentages for prisoners by offense to the composition

of the prison exit cohort.

Convicted offenders

On an average day in 1996, an estimated 5.3 million convicted offenders

were under the supervision of criminal justice authorities. Nearly 40%

of these offenders, about 2 million, had been using alcohol at the time

of the offense for which they were convicted.

Figure 25

As would be expected,

those convicted of public-

order crimes such as DWI,

weapons offenses, and

commercial vice are the most

likely to report the use of

alcohol at the time of the

offense (figure 27). For more

than 4 in 10 convicted

murderers, being held either

in jail or in State prison,

alcohol use is reported to

have been a factor in the

crime. Nearly half of those

convicted of assault and

sentenced to probation had

been drinking when the

offense occurred.

Figure 27

Figure 26

Regardless of the type of corrections

status, offenders were about equally

likely to have been drinking at the time

of the crime. What they consumed was

similar, with beer being the most

commonly used alcoholic beverage: 30%

of probationers, 32% of jail inmates, and

23% of State prisoners said that they

had been drinking beer or beer in combi-

nation with liquor prior to the commission

of the current offense (figures 28a, b,

and c). Consumption of wine alone was

comparatively rare among the surveyed

offender populations.

On average, the consumption of an

ounce of ethanol is equal to drinking

about two 12-ounce beers. Among

offenders who drank during the 8 hours

or less before the offense, the amount of

ethanol consumed varied by correctional

status and by offense.

Probationers were estimated to have

consumed about 4.7 ounces of ethanol,

the equivalent of about 9 beers. By

contrast, jail inmates self-reported

ethanol consumption equaling about 11

beers, and prisoners drank the equiva-

lent of 15 beers during a period of up to

8 hours prior to the crime. The highest

overall consumption prior to the offense

was reported by State prisoners serving

time after conviction for a property

offense. The amount of ethanol

consumed among offenders in the

immediate period (up to 8 hours) preced-

ing the offense was:

BJS surveys gather information on

the type of beverage consumed at the

time of the crime, the amount of each

type of alcoholic beverage consumed,

and the time spent drinking prior to the

occurrence of the offense. Together

with the offenders’ self-reported body

weight, it is possible to estimate the

BAC of each offender at the time the

offense was committed (figure 29).

These self-reports indicate that

those offenders in State prisons,

though a smaller percentage had been

drinking at the time, were considerably

more intoxicated when the crime

occurred than those on probation or

being held in local jails. Those

convicted offenders on probation and

in local jails appear, on average, to be

about as intoxicated as drivers in fatal

accidents (average BAC was about

0.17 g/dl for fatal accident drivers

from the FARS data for 1994) when

they committed their crimes. Such

comparative data on estimated levels

of intoxication at the time of the crime

have never been reported previously

for a nationally representative sample

of offenders.

Alcohol and Crime

The National Highway Traffic Safety Administra-

tion provided a formula to BJS which takes these

factors into account and reduces BAC based upon

a standardized rate at which the body metabolizes

ethanol. See

Appendix I

for details.

Figure 29

Note: See Appendix 1, page 32, for calculation of the BAC. Analysis was limited to

persons reporting drinking for 8 hours or less preceding the offense.

estimated average BAC at the time of the offense

While about 33% of State prisoners and nearly 40% of convicted

offenders under probation supervision or in local jails reported

drinking at the time of the offense, estimates of the average blood

alcohol concentration (BAC) suggest that State prisoners were

more severely intoxicated when they committed their crime.

Offenders on probation

and alcohol use

About a quarter of the women on

probation nationwide had been drinking

at the time of the offense compared to

more than 40% of male probationers

(figure 30). For those convicted of

public-order crimes, nearly two-thirds of

women and three-quarters of men had

been drinking at the time of the offense.

Probationers described a variety

of behaviors at some time in their lives

when drinking:

About half of all probationers reported

that they had driven a vehicle while

under the influence of alcohol.

About half of all probationers had

engaged in arguments with family or

friends while drinking.

About a third of probationers had gotten

into a physical fight with someone after

drinking.

More than a third of probationers

reported that they had consumed the

equivalent of a fifth of liquor in a day.

About 1 in 12 probationers said they had

a lost a job because of drinking.

Local jail inmates and alcohol use

As found among probationers,

convicted males in local jails were

more likely than convicted females to

report alcohol use at the time of the

offense, though the disparity by

gender was smaller (figure 32). For

every type of offense, except for

public order crimes, women in jail

reported greater use of alcohol at the

time of the offense than was the case

for women under probation supervi-

sion in the community (figure 30).

Jail inmates

drinking at the

time of the offense

Overall, about two-thirds of convicted offenders in

local jails who reported that they had been drinking

at the time of the offense were estimated to have had

a BAC level of 0.10 or higher.

Figure 33

About a third of all convicted

inmates in local jails described

themselves as having been daily

drinkers at the time of the offense

(figure 32). Among these daily drink-

ers, about 2 out of 3 said that they had

previously received some form of

alcohol treatment, with detoxification

the most commonly described inter-

vention. Among those who described

themselves as drinking less often,

about 2 out of 3 also reported prior

alcohol treatment

participation, most often in an

inpatient program.

The most recent census of the 3,300

local jails nationwide (1993) indicates

that about 10% of all jails maintain

special housing units for alcohol

detoxification. Less than 4% of local

jails in States in the Northeast,

however, describe having such units

available for housing inmates in need

of alcohol detoxification.

About 6 in 10 convicted jail inmates said that they had been

drinking on a regular basis during the year before the offense

for which they were serving time.

Nearly 2 out of 3 of these inmates, regardless of whether they

drank daily or less often, reported having previously been

in a treatment program for an alcohol dependency problem.

Figure 34

Inmates in State prisons

and alcohol use

The alcohol consumption patterns of

State prisoners differ markedly from jail

inmates and probationers; though the

prevalence of drinking is lower, the

estimated levels of intoxication at the

time of the offense are higher. A major

departure from other components of the

corrections population is that women

inmates report higher levels of intoxica-

tion at the time of the offense than male

inmates (figure 33).

Overall, State prison inmates report

having consumed an average of nearly 9

ounces of ethanol prior to the offense,

the equivalent of about three six-packs

of beer or two quarts of wine. The

median time spent drinking prior to the

crime was about 6 hours.

Intoxication levels vary by the amount

of time the offender spent drinking

before the crime but vary little by the

relationship between the victim and

offender in violent crimes.

The extent of alcohol involvement in

crime increases if victim use of alcohol

at the time of the offense is included.

While the NCVS does not ask crime

victims to indicate if they had been drink-

ing when the offense occurred, the

inmate surveys ask the offender to

indicate if he/she knew if the victim had

been drinking. Among violent offenders

in State prisons, 28% reported that they

had been using alcohol at the time of the

offense, 6% report only the victim had

been using alcohol, and 8% of violent

offenders report that both they and their

victim had been drinking (text table on

page 29). Manslaughter offenses and

offenses directed against a spouse or

intimate were the most likely to have

been alcohol-involved.

Among State prisoners, nearly 3 in

10 described themselves as daily

drinkers during the period preceding

their incarceration (figure 34). By type

of offense, there was little variation in

the percentage who described

themselves as drinking daily: only

those serving time for drug offenses

were less likely to report regular drink-

ing or drinking daily. Daily drinkers

reported that they began regular drink-

ing earlier, at less than age 17, and at

the time of the offense, they were

estimated to have had the highest

average BAC, about 0.30 g/dl.

for which they were in prison.

Victims of murderers in State prisonsDrinking at the

time of the

murder

Convicted murderers in State prisons reported that alcohol was a

factor in about half the murders they committed. Those who

murdered intimates reported drinking the largest quantity for the

longest period prior to the offense. They were estimated to have had

a comparatively high BAC, about 0.30, at the time of the murder.

About half of all State prison inmates describing themselves as daily

drinkers had received some form of treatment in the past. For most

the treatment was in the form of participation in a self-help group

such as Alcoholics Anonymous (AA).

Figure 37

About half the prisoners who

described themselves as daily drinkers

prior to entering prison, reported that

they had participated in an alcohol

treatment program at some time in

their lives (figure 36).

Among offenders in State prisons

who described themselves as drinkers,

offenders convicted of public-order

crimes were the most likely to report

having previously participated in an

alcohol treatment program.

About a third of daily drinkers in

State prisons had participated in

alcohol treatment programs 2 or more

times previously. Since admission to

prison, about 1 in 5 offenders who

described themselves as drinkers

joined an AA or Al-Anon type of group.

In 1995 a BJS census conducted

among prisons nationwide revealed

that 1,224 of the 1,375 State correc-

tional facilities (both confinement

facilities and community-based facili-

ties) and 121 of the 125 Federal

prisons and halfway houses provided

alcohol dependency treatment

programs. Among these 1,345 correc-

tional facilities with alcohol treatment

services, 1,075 were traditional

confinement facilities and 270 were

community-based primarily serving a

pre-release population.

Among the 1,196 confinement facili-

ties nationwide in 1995, 192 indicated

that a central mission of the facility

was to provide drug/alcohol treatment,

more than double the number of

prisons providing such services in

1990. Thirty-nine prisons described

their primary function as alcohol/drug

treatment.

In 1995 there were 110 privately

operated correctional facilities in the

U.S. under contract to State or

Federal authorities. Among these, 4

facilities, housing an average daily

population of 1,035 inmates,

described their primary function as

alcohol or drug treatment.

Appendix I

Formula for calculating BAC

The National Highway Traffic Admin-

istration has provided a formula that

permits an estimate of Blood Alcohol

Concentration (BAC) to be made based

upon the self-reported drinking behavior

of the offender immediately preceding

the commission of the offense. The

formula requires the collection of data

from offenders about the type of bever-

age consumed, the alcohol content of

that beverage, the quantity consumed,

the amount of time spent drinking, the

drinker’s gender, and the body weight of

the offender.

The formula for calculating BAC after

multiple hours of drinking (Widmark

Formula) is:

BAC(h)=[A/(r * p)/10]-(h* k)

where

BAC=Blood Alcohol Concentration at

time h

A=grams of ethanol consumed: which is

equal to (liquid ounces of ethanol *

.82)/.035

r=reduced body mass: which is .68 for

males and .55 for females

p=weight in kilograms: which is equal to

weight in pounds/2.2046

h=hours drinking

K=estimated rate at which the body

metabolizes ethanol which is .015 grams

per hour

Based on this formula, a male offender

who weighs 173 pounds and reported

consuming 12 beers in 4 hours before

the offense would have an estimated

BAC of 0.19 at the time of the crime.

To solve for BAC

1) 144 ounces beer * 4% alcohol

content=5.76 ounces of liquid ethanol

2) A=(5.76 * .82)/.035=134.95 grams of

ethanol

3) p=173 pounds/2.2046=78.47

kilograms

4) r * p=.68 * 78.47 kilograms=53.36

kilograms

5) h * k=4 hours * .015=.06

BAC (4 hours)=[(134.95/53.36)/10]-.06

=(2.527/10)-.06

Liquor law violations

on college campuses

Based upon a nationwide survey of

postsecondary institutions carried out

by the National Center for Education

Statisitics, in 1994 an estimated 13%

of 2- and 4-year colleges reported

on-campus arrests for liquor law viola-

tions. Liquor law violations generally

include prohibited manufacture, sale,

or possession of liquor and maintain-

ing illegal drinking places but exclude

public drunkenness offenses and

DUI/DWI.

An estimated 63% of public 4-year

universities reported arrests for liquor

law violations compared to 17% of

private 4-year schools. National

estimates of the number of arrests on

campus for 1994 were 20,430. Per

capita arrest rates averaged 1.404 per

thousand students nationwide but

varied substantially by type of school,

residency, size, and location:

Farris,

Campus Crime and Security at

Postsecondary Education Institutions,

Washington, D.C.: National Center for

Education Statistics, January 1997

(NCES 97-402).

Just over half of campus law enforce-

ment agencies at 4-year universities

and colleges with at least 2,500

students report that they operate

alcohol education programs. Gener-

ally, the larger the university the more

likely they are to maintain alcohol

education as a special unit or activity.

Public universities (59%) more often

reported the availability of such

programs and services than those

universities which were privately

operated (43%).
