Sexual Violence: Fact Sheet
OCCURRENCE
Variations in statistics result from
differences in how data sources define sexual violence and gather
information about it.
- Of all crimes, rape is one of the most
underreported, making it difficult to count (Bachar and Koss 2001). The
National Women’s Study found that 84% of women did not report their rapes
to police (Kilpatrick, Edmunds, and Seymour 1992).
- The National Violence Against Women
Survey estimated that 302,091 women and 92,748 men were raped in the 12
months prior to the survey administration. Victims often experience more
than one rape. Of those who were raped in the previous 12 months, women
experienced 2.9 rapes and men experienced 1.9 rapes, on average. (Tjaden
and Thoennes 2000).
- According to the National Violence
Against Women Survey, 1 in 6 women and 1 in 33 men in the United States
has experienced an attempted or completed rape at some time in their lives
(Tjaden and Thoennes 2000).
- In 8 out of 10 rape cases, the victim
knew the perpetrator (Tjaden and Thoennes 2000).
- The National College Women Sexual
Victimization Study estimated that between 1 in 4 and 1 in 5 college women
experienced completed or attempted rape during their college years
(Fisher, Cullen, and Turner 2000).
- According to the Youth Risk Behavior
Surveillance System (YRBSS), a national survey of high school students,
approximately 9% of students reported having been forced to have sexual
intercourse against their will in their lifetime. Female students (11.9%)
were more likely than male students (6.1%) to report having been sexually
assaulted. Overall, 12.3% of Black students, 10.4% of Hispanic students,
and 7.3% of White students reported forced sexual intercourse (CDC 2004).
- Based on a review of state records
pertaining to child abuse and neglect, 86,830 children in the United
States experienced sexual abuse in 2001 (DHHS 2003).
CONSEQUENCES
Physical
- Many long-lasting physical symptoms and
illnesses have been associated with sexual victimization including chronic
pelvic pain; premenstrual syndrome; gastrointestinal disorders; and a
variety of chronic pain disorders, including headache, back pain, and
facial pain (Koss and Heslet 1992).
- Between 4% and 30% of rape victims
contract sexually transmitted diseases, including HIV (Koss and Heslet
1992; Murphy 1990).
- A longitudinal study in the United
States estimated that over 32,000 pregnancies result each year from rape
in victims age 12 to 45 years (Holmes et al. 1996).
Psychological
Immediate Impacts
- Sexual violence victims exhibit a
variety of psychological symptoms that are similar to those of victims of
other types of trauma, such as war and natural disaster (Crowell and
Burgess 1996).
- Immediate reactions to rape include
shock, disbelief, denial, fear, confusion, anxiety, and withdrawal (Herman
1992).
- Symptoms of Post-Traumatic Stress
Disorder (PTSD) are usually present immediately after a rape. Victims may
experience emotional detachment, sleep disturbances, and flashbacks.
Approximately one third of rape victims have symptoms that continue for
three months or become chronic (Rothbaum et al. 1992).
Long-term Impacts
- Rape victims often experience anxiety,
guilt, nervousness, phobias, substance abuse, sleep disturbances,
depression, alienation, and sexual dysfunction. They often distrust others
and replay the assault in their minds, and are at increased risk of revictimization (DeLahunta 1997).
- Women reporting forced sex are at
significantly greater risk of depression and PTSD than those who have not
been abused (Campbell and Soeken 1999; Fergusson, Horwood, and Lynskey
1996; Levitan et al. 1998).
- Women with a history of sexual assault
are more likely to attempt or commit suicide than other women (Felitti et
al. 1998; Davidson et al. 1996; Luster and Small 1997; McCauley et al.
1997; Romans et al. 1995; Wiederman, Sansone, and Sansone 1998).
Social
- Rape can strain relationships because of
its negative effect on the victim’s family, friends, and intimate partners
(Crowell and Burgess 1996).
Health Behaviors
- Victims of sexual violence are more
likely than non-victims to engage in risky sexual behavior including
having unprotected sex, having sex at an early age, having multiple sex
partners, teen pregnancy, and trading sex for food, money, or other items
(Boyer and Fine 1992; Brener et al. 1999). Some researchers view these
consequences of sexual violence as vulnerability factors for future
victimization.
- Rape victims are more likely than
non-victims to smoke cigarettes, overeat, drink alcohol, and are not
likely to use seat belts (Koss, Koss and Woodruff 1991).

GROUPS AT RISK
- Women are more likely to be victims of
sexual violence than men. Of the rapes and sexual assaults reported in the
2002 National Crime Victimization Survey, 87% of the victims were women
and 13% were men (DOJ 2003). However, these findings may be somewhat
influenced by reluctance among men to report sexual violence.
- Sexual violence has been called a
“tragedy of youth” (Kilpatrick, Edmunds, and Seymour 1992). Sexual
violence starts very early in life. More than half of all rapes (54%) of
women occur before age 18; 22% of these rapes occur before age 12 (Tjaden
and Thoennes 2000).
- According to the National Violence
Against Women Survey, American Indian and Alaskan Native women were
significantly more likely (34%) to report that they were raped than
African American women (19%) or White women (18%). (Tjaden and Thoennes
2000).
RELATIONSHIP BETWEEN VICTIM AND PERPETRATOR
- In 8 out of 10 rape cases, the victim
knew the perpetrator (Tjaden and Thoennes 2000).
- In the National Violence Against Women
Survey, 64% of women and 16% of men reported being raped, physically
assaulted, or stalked by an intimate partner. This includes a current or
former spouse, cohabitating partner, boyfriend/girlfriend, or date (Tjaden
and Thoennes 2000).
- In the National Women’s Study, intimate
partners (current or former spouses or boyfriends) represented 19% of
perpetrators, family members represented 27% of perpetrators, and 29% were
relatives, friends or acquaintances. Only 22% of perpetrators were
strangers (Kilpatrick, Edmunds, and Seymour 1992).
VULNERABILITY
FACTORS FOR VICTIMIZATION
The first step in preventing sexual
violence is to identify and understand vulnerability factors. A
vulnerability factor is anything that increases the likelihood that a person
will suffer harm. Research has identified the following vulnerability
factors for sexual violence (Krug et al. 2002):
- Young age. Young women are at
higher risk of being raped than older women (Acierno et al. 1999; Heise,
Pitanguy, and Germain 1994). More than half of all rapes (54%) of women
occur before age 18; 22% occur before age 12 (Tjaden and Thoennes 2000).
- Drug or alcohol use. In a large
longitudinal study, recreational drug use was found to increase the
likelihood of rape (Kilpatrick et al. 1997). Research on the relationship
between alcohol use and sexual violence is not as clear. However, drug and
alcohol use may place women in settings where they are more likely to
encounter potential perpetrators (Crowell and Burgess 1996).
- Prior history of sexual violence.
A study conducted in the United States found that women raped before the
age of 18 were twice as likely to be raped as adults, compared to those
without a history of sexual abuse (Tjaden and Thoennes 2000).
- Multiple sexual partners. Women
with many sexual partners are at increased risk of experiencing sexual
abuse (Crowell and Burgess 1996; Fergusson, Horwood and Lynskey 1997).
Many researchers believe that having multiple partners is both a
vulnerability factor and a consequence of sexual abuse. Such behavior is a
coping strategy for sexual violence that increases the likelihood that a
woman will be revictimized.
- Poverty. Poverty may make the
daily lives of women and children dangerous (e.g. walking alone at night,
less parental supervision) and put them at greater risk for experiencing
sexual violence (Krug et al. 2002). In addition, poor women may be at risk
for sexual violence because their economic status forces them into certain
high risk occupations, including prostitution (Irwin et al. 1995).
RISK FACTORS FOR
PERPETRATION
The following factors have been identified
as increasing the risk that a man will commit rape. These factors relate to
individual attitudes and beliefs as well as social conditions (Krug et al.
2002):
Individual Factors
- Alcohol and drug use
- Coercive sexual fantasies
- Impulsive and antisocial tendencies
- Preference for impersonal sex
- Hostility towards women
- History of sexual abuse as a child
- Witnessed family violence as a child
Relationship Factors
- Associate with sexually aggressive and
delinquent peers
- Family environment characterized by
physical violence and few resources
- Strongly patriarchal relationship or
family environment
- Emotionally unsupportive family
environment
Community Factors
- Poverty, mediated through forms of male
identity crisis
- Lack of employment opportunities
- Lack of institutional support from
police and judicial system
- General tolerance of sexual assault
within the community
- Weak community sanctions against
perpetrators of sexual violence
Societal Factors
- Societal norms that support sexual
violence
- Societal norms that support male
superiority and sexual entitlement
- Weak laws and policies related to gender
equity
- High levels of crime and other forms of
violence
A combination of societal, relational, and
individual factors, including biological and psychological characteristics,
may explain perpetration of sexual violence (Malamuth 1998).
