Some statistics on rape:
Thought I throw out some numbers. The main numbers given are from RAINN as they used a variety of sources from the US government and I needed to start somewhere. I added other information from websites in italic to give a broader perspective since numbers will vary wildly depending on sources. I did not attempt to distinguish between numbers given for certain years or certain periods, nor did I try to make a distinction between sexual assault and rape where some statistics made that difference at some point and others didn't. Websites who did not mention sources were ignored. All number should be for the US. Basically: statistics are a mess and blurry at best, so there's no use in debating exact numbers.
Victims:
- Women who were the victim of attempted or completed rape: 1 out of 6
Other sources give number from 1 in 10 up to 1 in 4
- Men who were the victim of attempted or completed rape: 1 out of 33
Other sources give numbers ranging from 1 in 71, up to 1 in 10
Perpetrators (numbers not given by RAINN):
- Nearly one in 10 women was victim of completed or attempted rape by an intimate partner in her lifetime (including completed, attempted or alcohol/drug-facilitated completed penetration). Other sources mention numbers ranging from 46% to 1 in 7.
- An estimated 16.9% of women and 8.0% of men have experienced sexual violence other than rape (being made to penetrate an intimate partner, sexual coercion, unwanted sexual contact, and non-contact unwanted sexual experiences) by an intimate partner in their lifetime.
- Approximately one in 45 men has been made to penetrate an intimate partner during his lifetime.
- In 8 out of 10 cases, the victim knew the person who sexually assaulted them
- In a survey answered by hundreds of rape and sexual assault support agencies, they estimated that 93.7 percent of male rape perpetrators are male and 6.3 percent were female.
Lifetime rate of rape /attempted rape for women by race:
- All women: 17.6%
- White women: 17.7%
- Black women: 18.8%
- Asian Pacific Islander women: 6.8%
- American Indian/Alaskan women: 34.1%
- Mixed race women: 24.4%
No numbers found for men.
Numbers for age of victims:
- 15% of sexual assault and rape victims are under age 12.
- 29% are age 12-17.
- 44% are under age 18.3
- 80% are under age 30.3
- 7% of girls in grades 5-8 and 12% of girls in grades 9-12 said they had been sexually abused.
- 3% of boys grades 5-8 and 5% of boys in grades 9-12 said they had been sexually abused.
Other sources give roughly the same numbers and or give additional info:
- 12.3% of women were age 10 or younger at the time of their first rape/victimization, and 30% of women were between the ages of 11 and 17
- 27.8% of men were age 10 or younger at the time of their first rape/victimization
- More than one-third of women who report being raped before age 18 also experience rape as an adult
- 1 in 9 girls and 1 in 53 boys under the age of 18 experience sexual abuse or assault at the hands of an adult.
Other sources mention 1 in 4 for girls and 1 in 6 for boys
About perpetrators of juvenale sexual assault:
- 34.2% of attackers were family members.
Other sources mention 34% as well
- 58.7% were acquaintances.
- Only 7% of the perpetrators were strangers to the victim.
The perpetrators were...
- 80 % was a parent
- 6% were other relatives
- 4% were unmarried partners of a parent
- 5% were "other" (from siblings to strangers).
Other sources give additional information:
96% of people who sexually abuse children are male, and 76.8% of people who sexually abuse children are adults
Effects of rape. Victims of sexual assault are:
- 3 times more likely to suffer from depression.
- 6 times more likely to suffer from post-traumatic stress disorder.
- 13 times more likely to abuse alcohol.
- 26 times more likely to abuse drugs.
- 4 times more likely to contemplate suicide.
Crime reports (information not given by RAINN)
- Rape is the most under-reported crime; 63% of sexual assaults are not reported to police. Other sources mention "The FBI finds that only 1 in 4 rapes are published in the Uniform Crime Reports. The Uniform Crime Reports do not include rapes that end in death, since those are reported as homicides." Wikipedia mentions 84% went unreported to the police.
- Some types of rape are excluded from official reports altogether (the FBI's definition, for example, used to exclude all rapes except forcible rapes of females), because a significant number of rapes go unreported even when they are included as reportable rapes, and also because a significant number of rapes reported to the police do not advance to prosecution. As well as the large number of rapes that go unreported, only 25% of reported rapes result in arrest.
- Data on the prevalence of rape vary greatly depending on what definition of rape is used. The FBI recorded 85,593 rapes in 2010, while the Centers for Disease Control counted nearly 1.3 million incidents in that same year. It should however be noted that the CDC's definition of rape "represents the public health perspective" and takes into account the ability of the victim to consent to sex because he or she had been drinking or taking drugs while the FBI defines rape as "Penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim."
- Only 12% of child sexual abuse is reported to the authorities
- The prevalence of false reporting is between 2% and 10%. For example, a study of eight U.S. communities, which included 2,059 cases of sexual assault, found a 7.1% rate of false reports. Astudy of 136 sexual assault cases in Boston found a5.9% rate of false reports. Researchers studied 812 reports of sexual assault from 2000-03 and found a 2.1% rate of false reports.
Pregnancies Resulting from Rape:
In 2012, 346,830 women were raped. According to medical reports, the incidence of pregnancy for one-time unprotected sexual intercourse is 5%. By applying the pregnancy rate to 346,830 female survivors, RAINN estimates that there were 17,342 pregnancies as a result of rape in 2012.
This calculation does not account for the following factors which could lower the actual number of pregnancies:
- Rape, as defined by the NCVS, is forced sexual intercourse. Forced sexual intercourse means vaginal, oral, or anal penetration by offender(s). This category includes incidents where the penetration is from a foreign object such as a bottle. Certain types of rape under this definition cannot cause pregnancy.
- Some victims of rape may be utilizing birth control methods, such as the pill, which will prevent pregnancy.
- Some rapists may wear condoms in an effort to avoid DNA detection.
- Vicims of rape may not be able to become pregnant for medical or age-related reasons.
This calculation does not account for the following factors which could raise the actual number of pregnancies:
- Medical estimates of a 5% pregnancy rate are for one-time, unprotected sexual intercourse. Some victimizations may include multiple incidents of intercourse.
- Because of methodology, NCVS does not measure the victimization of Americans age 12 or younger. Rapes of these young people could results in pregnancies not accounted for in RAINN's estimates.
