Additional information about the data 34

This report contains a series of tables and figures that describe homicide patterns and trends in the United States from 1980 through 2008. It also includes overall homicide rates for 2009 and 2010 (for which detailed data are not yet available).

Data in this report are from the FBI's Supplementary Homicide Reports (SHR), unless otherwise noted. The SHR Program of the FBI collects yearly supplementary homicide data regarding homicides committed in the United States. Statistics in this report detail homicide trends by age, sex, and race, including homicides of children under age 5 and of persons age 65 or older. It examines the relationship between the victim and the offender, particularly in cases of intimate and family homicide. The report also examines multiple victim and offender homicides, circumstances surrounding the death, justifiable homicides, law enforcement officers killed, homicides cleared, and homicide trends by city size and weapon use.

These data may differ slightly from previously published versions because of updates to the data file, changes to the imputation methods used, and refinements in the analyses. (See Methodology for more information on the imputation methods used in this report.) In addition, analyses presented here include data from 1980 through 2008 only. This modification was made, in part, to reflect revisions in the SHR in 1980.

The SHR are available at the National Archive of Criminal Justice Data. Spreadsheets used to generate the figures in this report are available on the BJS website.

Long term trends and patterns

In the last decade (since 2000) the homicide rate declined to levels last seen in the mid-1960s

e homicide rate doubled from the early 1960s to the late 1970s, increasing from 4.6 per 100,000 U.S. residents in 1962 to 9.7 per 100,000 by 1979 ( gure 1). (See Methodology for information on rate calculations.)

In 1980 the rate peaked at 10.2 per 100,000 and subsequently fell to 7.9 per 100,000 in 1984.

e rate rose again in the late 1980s and early 1990s to another peak in 1991 of 9.8 per 100,000.

e homicide rate declined sharply from 9.3 homicides per 100,000 in 1992 to 4.8 homicides per 100,000 in 2010.

The number of homicides reached an all-time high of 24,703 homicides in 1991 then fell rapidly to 15,522 homicides by 1999

e number of homicides increased steadily from the early 1950s until the mid-1970s ( gure 2).

Between 1999 and 2008, the number of homicides remained relatively constant, ranging from a low of 15,552 homicides in 1999 to a high of 17,030 homicides in 2006. ese homicide numbers were still below those reported in the 1970s, when the number of reported homicides rst rose above 20,000 (reaching 20,710 in 1974).

Homicide Trends in the United States, 1980-2008

PAT TERNS & TRENDS

The demographic characteristics of homicide victims and o enders were di erent from the characteristics of the general population

Based on available data from 1980 to 2008--

Blacks were disproportionately represented as both homicide victims and offenders. The victimization rate for blacks (27.8 per 100,000) was 6 times higher than the rate for whites (4.5 per 100,000). The offending rate for blacks (34.4 per 100,000) was almost 8 times higher than the rate for whites (4.5 per 100,000) (table 1).

Males represented 77% of homicide victims and nearly 90% of offenders. The victimization rate for males (11.6 per 100,000) was 3 times higher than the rate for females (3.4 per 100,000). The offending rate for males (15.1 per 100,000) was almost 9 times higher than the rate for females (1.7 per 100,000).

Approximately a third (34%) of murder victims and almost half (49%) of the offenders were under age 25. For both victims and offenders, the rate per 100,000 peaked in the 18 to 24 year-old age group at 17.1 victims per 100,000 and 29.3 offenders per 100,000.

Trends by age

Young adults had the highest homicide victimization and o ending rates

Homicide victimization rates for teens and young adults increased rapidly in the late 1980s and early 1990s, peaking in 1993 at 12 homicides per 100,000 for teens and 24.8 homicides per 100,000 for young adults.

The homicide victimization rate for children under age 14 was the lowest of all age groups, peaking in 1993 at a high of 2.2 homicides per 100,000. By 2004, this rate had declined to the lowest level recorded--1.4 homicides per 100,000--and remained stable through 2008 at 1.5 homicides per 100,000 ( gure 3).

The homicide victimization rate for teens (14 to 17 years old) increased almost 150% from 4.9 homicides per 100,000 in 1985 to 12.0 homicides per 100,000 in 1993. Since 1993, the victimization rate for teens has declined to 5.1 homicides per 100,000.

In 2008, young adults (18 to 24 years old) experienced the highest homicide victimization rate (13.4 homicides per 100,000).

In the early 1980s, 25 to 34 year-olds had the highest homicide victimization rate--18.6 homicides per 100,000. By 2008, this rate had fallen to 10.7 homicides per 100,000, a 42% reduction.

Homicide victimization rates for adults ages 35 to 49 and 50 or older have remained stable since 1999 at between 5.7 and 5.9 homicides per 100,000 for adults ages 35 to 49 and between 2.5 and 2.7 homicides per 100,000 for adults ages 50 or older.

Homicide o ending rates followed a pattern similar to victimization rates

The offending rates for teens (14 to 17 years old) and young adults (18 to 24 years old) increased dramatically in the late 1980s while the rates for older age groups declined ( gure 4).

From 1980 to 2008, young adults (18 to 24 years old) have consistently had the highest offending rate. This rate nearly doubled from 1985 to 1993, going from 22.1 offenders per 100,000 young adults to 43.1 offenders per 100,000.

Since 1993, the offending rate for 18 to 24 year-olds has declined to 24.6 offenders per 100,000 in 2008.

The offending rate for teens (14 to 17 years old) increased substantially from 10.4 offenders per 100,000 in 1985 to 30.7 offenders per 100,000 by 1993. After 1993, the rate fell so much that by 2000, the offending rate for teens was near its 1985 level, at 9.5 offenders per 100,000.

The offending rates for adults ages 35 to 49 and 50 or older have remained relatively stable since 2000, at between 4.8 and 5.1 offenders per 100,000 for adults age 35 to 49 and between 1.3 and 1.5 offenders per 100,000 for adults age 50 or older.

Homicide Trends in the United States, 1980-2008

PAT TERNS & TRENDS

After many years of decline, the average age of both victims and o enders has leveled o

The average age of-- victims fell from 34.1 years in 1980 to 31.3 years in 1994, then

increased to 32.7 years by 2008 ( gure 5) offenders fell from 29.6 years in 1980 to 26.4 years in 1994, then

increased to 28.8 years in 2008 both offenders and victims increased slightly in recent years, yet

remained lower than they were prior to the late 1980s.

The age distribution of homicide victims and o enders di ered by type of homicide

From 1980 to 2008-- A quarter of the victims (24%) of gang-related homicides were

under age 18. Juveniles were also a fifth (19%) of persons killed by family members, and they represented more than a quarter (28%) of persons killed by arson or by poison (table 2). Victims age 50 or older were 39% of workplace homicide victims and 34% of victims of homicide by poison.

Younger victims were more likely than older victims to know the o ender ( gure 6)
