Felony Sentences in State
Courts, 1998
By Matthew R. Durose
David J. Levin
and Patrick A. Langan, Ph.D.
BJS Statisticians
In 1998 State courts convicted nearly
930,000 adults of a felony. Forty-four
percent of convicted felons were
sentenced to a State prison, and 24%
were sentenced to a local jail (usually
for a year or less). The remaining 32%
were sentenced to probation. These
findings come from a survey conducted
every 2 years and is the Nation’s sole
source of statistical information on the
sentences felons receive in State
courts nationwide.
National Judicial Reporting Program
The “National Judicial Reporting
Program” (NJRP) compiles detailed
information on the sentences and
characteristics of convicted felons.
Previous national surveys of felony
sentencing in State courts were
conducted in 1986, 1988, 1990, 1992,
1994, and 1996.1

Highlights
• In 1998 State courts convicted
927,717 adults of a felony. Federal
courts convicted 50,494, bringing the
combined U.S. total to 978,211. State
courts accounted for 95% of the
national total.
• Drug offenders were 33.9% of felons
convicted in State courts in 1998.
Property offenders made up 30.5%;
violent offenders, 17.8%; and those
convicted of weapon offenses and
other nonviolent crimes made up the
rest (17.8%).
• State courts sentenced 44% of
convicted felons to a State prison,
24% to a local jail, and 32% to straight
probation with no jail or prison time to
serve.
• State courts sentenced to death
1% of those convicted of murder.

• The average sentence length to
State prison has decreased since
1990 (6 years versus almost 5
years), but felons sentenced in 1998
were likely to serve more of that
sentence before release (33% versus
47%).



• Guilty pleas accounted for 94% of
felony convictions in 1998. Trial
convictions accounted for the remaining 6%.
• Nationally, of the felons convicted in
1998, 55% were white, 44% were
black, and 1% were other races. The
average age of felons convicted in
State courts in 1998 was 31.
• Females account for an increasing
portion of felons convicted in State
courts. In 1990, females were 14%
of convicted felons; in 1998, 17%.

• The average sentence to local jail
• In 1998 the average time from arrest
was 6 months. The average probation to sentencing was just over 7 months
sentence was 3 years and 4 months.
(214 days).
A fine was imposed on 21% of
convicted felons, restitution on 13%,
community service on 6%, and treatment was ordered for 6%.

The 1998 survey was based on a
sample of 344 counties (out of the
Nation’s approximately 3,100 counties)
selected to be nationally representative.
The 344 included the District of Columbia and at least 1 county from every
State except, by chance, Delaware and
Montana. Among the 344 sampled
counties, 2 sentenced no felons during

2 Felony Sentences in State Courts, 1998

1998. The 1998 survey excluded
Federal courts and those State or local
courts that did not adjudicate adult
felony cases.
According to the BJS Federal Justice
Statistics Program, Federal courts
convicted 50,494 persons of a felony in
1998 (see page 3).2 That number
represents 5% of the combined State
and Federal total number of felony
convictions during 1998.

283,000 (30.5%) for the property
offenses of burglary, larceny, fraud,
and forgery; 314,600 (33.9%) for drug
offenses; and 31,900 (3.4%) for
weapon offenses (table 1). The
remaining 133,600 (14.4%) consisted
of persons convicted of nonviolent
offenses such as receiving stolen
property and escaping custody.
Marijuana trafficking convictions were
2.5% of the conviction total, and
marijuana possession convictions were
3.6% of the total.

The vast majority of all felony convictions in the United States occur in
State courts. Overall, Federal courts
account for a relatively small number.
• In 1998 Federal courts convicted
50,494 persons of a violent, property,
drug, or other felony. State courts
convicted 927,717 bringing the
combined U.S. total to 978,211 felons
convicted. Federal courts accounted
for 5% of the national total.
• Violent offenses comprised 5% of
felony convictions in Federal courts but
18% of those in State courts.

• In 1998, 82% of felons convicted in
Federal courts were sentenced to
incarceration. The remaining 18%
received probation. State courts
sentenced 68% of felons to incarceration (prison or jail) and 32% to straight
probation.
• The average Federal incarceration
sentence was just over 5 years in
1998. By contrast, State incarceration
sentences (prison or jail) had an
average of 3 years and 3 months.
• Federal drug offenders received
incarceration terms that were about
twice the length of drug offenders in
State courts (6 years and 7 months
versus 2 years and 7 months).

• In 1998 Federal offenders released
from prison served an average of 91%
of their prison term before release.
Felons convicted in State courts
served a significantly smaller proportion of their total incarceration
sentence. For instance, State prisoners (not including felons sentenced to
jail) served about 47% of their total
prison sentence in 1998.
Source of Federal data: Federal statistics shown in the above table are from
the same database that was used to
create tables 5.1 and 5.2 of the BJS
publication Compendium of Federal
Statistics, 1998 (NCJ 180258). Tables
5.1 and 5.2 figures differ from the
above figures because of differences
in how offenses were defined.

same time) or consecutively (one after
another). For persons with consecutive
sentences, the total time is the sum of
the sentence lengths, and for persons
with concurrent sentences, the total
time is the same as the longest
sentence. For persons convicted of a
single offense, the total time refers
simply to the sentence for that offense.
Whenever an offender received a
prison sentence range, such as 5 to 10
years, the total time refers to the
maximum.
For the Nation in 1998, the mean felony
sentence to incarceration (prison or jail)
was 3 years and 3 months; the median
was 1 year and 6 months (table 3).
State prison sentences
In 1998 the mean length of sentences
to State prison was almost 5 years; the
median term was 3 years. The mean
prison sentence for murder and
nonnegligent manslaughter was nearly
22 years; the median was 25 years.
Life sentences are rare among
convicted felons, whether measured as
a percentage of all sentences (0.5%)
or as a percentage just of prison
sentences (1.1%). However, among
persons convicted of murder or
nonnegligent manslaughter, 26% were
sentenced to life in prison, and 1%
were sentenced to death.
Among persons convicted of murder or
nonnegligent manslaughter and
sentenced to prison, 27% were
sentenced to life in prison, and 1%
were sentenced to death. When
considering those convicted of murder
specifically (not including nonnegligent
manslaughter), 32% were sentenced
to life, and 1% were sentenced to
death. Again, among those convicted
of murder specifically and sentenced
to prison, 34% were sentenced to life
in prison, and 1% were sentenced to
death.3

Not all persons convicted of murder were
subject to the death penalty. Thirty-eight States
authorized the death penalty in 1998. Within
those 38, only certain types of murder were
capital offenses.

Jail and probation sentences
Among felons who received a sentence
to local jail in 1998, the mean sentence
was 6 months, and the median was 4
months. Probation sentences had a
mean length of 3 years and 4 months
and a median of 3 years (table 3).

under supervision in the community.
To calculate time to be served by
felons sentenced in 1998, the fraction
of their sentence they might reasonably
be expected to serve was obtained
from records of inmates released from
prison in a recent year. Life sentences
and death sentences were excluded
because it is not possible to specify the
percentage served. The percentage of
the sentence that released inmates had
served was applied to felons sentenced
to prison in 1998.
Based on data collected by BJS in its
“National Corrections Reporting
Program,” inmates released from
prisons in 1998 had served an average
of 47% of their total sentence in prison
(table 4). The percentage of sentence
served ranged from 60% for those
convicted of weapon offenses to a low
of 40% for those convicted of drug
possession.

Applying these percentages to State
prison sentences received in 1998, it is
estimated that felons sentenced in
1998 would serve just over 2 years, or
47% of their average 5-year prison
sentence.
Since life sentences and death are rare
for most types of crimes, this method
gives reasonably sound estimates of
time to be served for most offenses
(assuming, among other things, that
prison release policies applicable to
persons sentenced in 1998 are not
markedly different from those governing recent releases). However, life
sentences and death are not rare for
murder, though they are rare for
nonnegligent manslaughter. Consequently, time to be served shown for
“murder and nonnegligent manslaughter” perhaps substantially underestimates the amount of time all persons
convicted of these offenses are likely to
serve since the time only applies to
persons not receiving a life or death
sentence.

Table 4. Estimated time to be served in State prison, by offense, 1998

Estimated State prison time to be
served
The amount of time felons actually
serve in prison is typically a fraction of
the total sentence received. Two
primary reasons explain the difference
between sentences received and time
served:
In States that impose indeterminate
sentences, a judge specifies the
minimum and/or maximum sentence
length, but a parole board decides
when the prisoner will actually be
released.
In most but not all States, prisoners
gain early release through time credits
that they receive automatically or that
are granted to them for good behavior
or special achievements  provisions
that are intended to help correctional
officials manage institutional
populations.
For both types of sentence reduction,
released offenders usually serve the
remaining portion of their sentences

Felony convictions and sentences relative to the number of arrests, 1998
The number of State felony convictions
in 1998 was compared to the number
of crimes reported to police and the
number of arrests made for these
crimes in 1998. Comparisons are
limited to crimes likely to be felonies.
These aggregate numbers should not
be interpreted as tracking individual

of conviction and a prison sentence,
given an arrest for a felony.
For example, the FBI reports that in
1998 almost 15,400 adults were
arrested for murder (including nonnegligent manslaughter). That year, 9,158
persons were convicted of murder, and

Method of conviction
Of the 927,717 convicted felons, the vast majority  about
872,000, representing 94% of those sentenced for a felony in 1998
 pleaded guilty. The rest were found guilty either by a jury or by
a judge in a bench trial (tables 9 and 10). Persons convicted of
murder were the least likely to have pleaded guilty (55%) and the
most likely to have been convicted by a jury (38%).
In 1998 violent crime accounted for most jury trials. Of all jury trial
felony convictions in 1998, 51% (15,515 cases) were for violent
crime; 49% (14,966 cases) were for nonviolent crime. Juries
convicted 3,471 persons of murder in 1998, and 4,898 of aggravated assault.

Note: Where the data indicated affirmatively that a particular additional penalty was
imposed, the case was coded accordingly. Where the data did not indicate affirmatively
or negatively, the case was treated as not having an additional penalty. These procedures
provide a conservative estimate of the prevalence of additional penalties. A felon receiving
more than one kind of additional penalty appears under more than one table heading.
This table is based on an estimated 927,717 cases.
a
Includes nonnegligent manslaughter.
b
Includes rape.
c
Includes offenses such as negligent manslaughter and kidnaping.
d
Includes motor vehicle theft.
e
Includes forgery and embezzlement.
f

Additional penalties
Besides being sentenced to incarceration or probation, 36% or more of
convicted felons also were ordered to
pay a fine, pay victim restitution,
receive treatment, perform community
service, or comply with some other
additional penalty (for example,
undergo house arrest or appear
periodically for drug testing). A fine
was imposed on at least 21% of
convicted felons (table 12).

Trends in the United States:
1990 to 1998
Number of convictions increasing
State courts convicted 927,717 adults
of a felony in 1998. That total is 12%
greater than the number convicted in
1990. The general trend has been
upward since 1990.

Increasing likelihood of arrest leading
to conviction
The likelihood of a felony arrest leading
to a felony conviction is approximated
by dividing the number of adult felony
convictions in a year by the number of
adult felony arrests that year. In 1998,
for example, robbery convictions
totaled 38,784, and robbery arrests
totaled 88,356, indicating about a 44%
likelihood of conviction for robbery.

Although the Nation’s annual arrest
statistics do not distinguish felony from
misdemeanor arrests, this method for
estimating the likelihood of conviction
from aggregate statistics is still valid for
certain crimes such as robbery
that State law always or nearly always
defines as felonies.





Since 1990 the likelihood of an arrest
leading to a conviction has generally
risen for all crimes.
Case processing time
Cases took the courts about the same
time to process in 1990 and 1998. In
1990 and 1998 the average length of
time from arrest to sentencing was just
over 7 months.

Guilty pleas
An indirect measure of how well courts
keep pace with a growing workload is
the percentage of cases disposed by
guilty plea. Because guilty pleas take
less time than trials, a rising workload
might exert pressure on prosecutors
and judges to dispose of more cases
by plea rather than trial. The data
contain evidence of more guilty pleas.
In 1990 guilty pleas accounted for 91%
of all felony convictions, and trials
accounted for the remaining 9%.
Corresponding figures for 1998 were
94% guilty pleas and 6% trials. Since
1990 guilty pleas have accounted for
at least 89% of felony convictions.
Aging of convicted felons
The average age of the American
population is rising, a trend reflected in
the changing average age of convicted
felons. In 1990, persons age 30 or
older comprised 74% of adults (age 18
and older) in the U.S. population and
accounted for 42% of persons
convicted; in 1998, persons age 30 or
older comprised 78% of adults (age 18
or older) in the U.S. population and
accounted for 52% of persons
convicted. The median age of
convicted felons was 28 years in 1990
but 30 years in 1998.

Prior to being freed, inmates released
from State prison in 1990 had served,
on average, a third of the sentence
imposed on them by the court. In
1998 inmates were released after
serving approximately half of their
court-imposed sentence. While prisoners are serving a growing percentage
of their court-imposed sentence, the
average court-imposed sentence has
been decreasing.
In 1990 the typical felon received a
6-year sentence and (assuming a
person sentenced in 1990 will serve the
same fraction of his/her sentence as
was typical among persons released in
1990) would serve a third of that
sentence before release, or 2 years.
By contrast, in 1998 the typical felon
received a 5-year sentence but
(assuming a person sentenced in 1998
will serve the same fraction of his/her
sentence as was typical among
persons released in 1998) would serve
half of that sentence before release, or
2 years and 3 months.

Methodology

Of these, 290,800 cases were in the 75
largest counties.

Sampling
In 1988 a sample of 300 counties was
drawn for the 1988 NJRP survey. With
little exception, these same 300
counties were the source of NJRP data
for 3 subsequent NJRP surveys (1990,
1992, 1994). For the 1996 NJRP
survey a new sample was drawn,
consisting of 344 counties. The 344
counties included 98 that had been in
the NJRP sample in the 4 previous
surveys (1988, 1990, 1992, 1994) and
246 that had never been in an NJRP
sample. The 98 consisted of 80
counties selected by chance alone;
plus 18 of the Nation’s largest counties
selected not by chance but (given their
large 1995 population size) with
certainty. The same 344 counties were
used for the 1998 NJRP survey.
The 1998 survey was based on a
two-stage, stratified cluster sampling
design. In the first stage the Nation’s
3,195 counties or county equivalents
were divided into 14 strata (see appendix table 1, page 14). Each county was
assigned to one stratum by meeting the
conditions for that stratum.
The stratum that a county was
assigned depended on answers to
these three questions:
1. Is the county among the Nation’s 75
largest according to 1995 resident
population?
2. In what type of State is the county?
(A State where data collection is generally not costly? One where data collection is generally moderately costly?
One where data collection is generally
very costly?)
3. What is the size of the county’s
1995 resident population?
At the second stage of sampling, a
systematic sample of felons sentenced
for murder/nonnegligent manslaughter,
sexual assault, robbery, aggravated
assault, burglary, felony larceny/motor
vehicle theft, fraud/forgery/embezzlement, drug trafficking, drug possession, weapon offenses, and other
offenses was selected from each
county’s official records. The total
sample numbered 446,682 cases.

Rates at which cases were sampled
varied by how the data were submitted,
by stratum and by crime type (appendix
table 2, page 14).

from the “other felonies” category and
shown separately in the report’s tables.
Additional details on the sampling are
in the BJS publication Felony
Sentences in State Courts, 1996 (NCJ
173939).
Sampling error

Before the sample of cases was drawn,
each felon sentenced in the sampled
county in 1998 was placed into 1 of the
11 offense categories identified above.
If the felon was convicted of more than
one felony offense, the offense
category was the most serious offense.
The hierarchy from most to least
serious offense was murder, sexual
assault, robbery, aggravated assault,
burglary, drug trafficking, weapons,
forgery/fraud/embezzlement, larceny/
motor vehicle theft, drug possession,
and all other felonies.
The hierarchy was determined from an
analysis of two factors that reflect how
seriously the justice system treats
different offenses: the sentence length
imposed and the time actually served in
prison before release. In general, the
higher the offense is in the hierarchy,
the more serious it is in terms of the
two factors.
Sample selection procedures gave
each sentenced felon a single chance
to be in the sample. However, felons
who appeared in court on more than 1
day for different offenses and received
a sentence at each reappearance had
more than a single chance.
At the data analysis stage, cases were
aggregated according to their offense
designation at the time of sampling,
with the single exception of “other
violent.” “Other violent” is a category
shown in the report’s tables, but it was
not a category at sampling. The “other
violent” category was formed from the
sampling category “other felonies.”
That is, after sampling, sampled cases
designated “other felonies” were coded
“violent,” “nonviolent,” or “not ascertained,” based on data available on
them. Cases coded “not ascertained”
were rare. For data analysis, cases
coded “other violent” were removed

NJRP data were obtained from a
sample and not from a complete
enumeration; consequently, they are
subject to sampling error. A standard
error, which is a measure of sampling
error, is associated with each number
in the report. In general, if the difference between two numbers is at least
twice the standard error of that difference (the criterion used in this report),
there is at least 95% confidence that
the two numbers do in fact differ; that
is, the apparent difference is not simply
the result of surveying a sample rather
than the entire population.
National estimates of the number of
convictions for individual crime categories and for the aggregate total had a
coefficient of variation of 3.8%.
Standard errors for each table in the
report are available on the Internet:
<http://www.ojp.usdoj.gov/bjs/abstract/
fssc98.htm>. Standard errors did not
take into account missing data, which
are sometimes substantial for certain
tables.
Sources of data
State courts were the source of NJRP
data for about 61% of the 344 counties
sampled. For other counties, sources
included statistical agencies, sentencing commissions, department of public
safety, probation departments, state
police departments, and department of
corrections. Individual-level NJRP
records were obtained through a
variety of collection methods, including
electronically (88% of the counties) and
manually (12%).
Electronic methods of data submission
included diskettes, magnetic tape, and
Internet transmission. Manual methods
included photocopies of official
documents, survey questionnaires

All data were collected by the U.S.
Bureau of the Census.

In the four counties sampled from
Maryland and in two other counties Wood (WI) and Mercer (NJ) - it was
impractical to target sentences in 1998.
Cases sampled from these counties
were all sentenced in 1999.
Note that the 1998 conviction data that
were submitted by two counties - San
Bernardino (CA) and Boulder (CO) - did
not conform to definitional guidelines.
Consequently, the 1996 conviction data
that were submitted by San Bernardino
and Boulder counties for the 1996
survey were used in their place.
Crime definitions
