Rape

Rape is usually defined as having sexual intercourse with a person who does not want to, or cannot consent. Consent is when someone agrees of their own choice without being forced to. In France it is more widely defined as 'unwanted sexual penetration'. Rape is a form of sexual assault. In most countries, rape is one of the most serious crimes. The International Criminal Court can also condemn it as a "crime against humanity", if done by a group. A person who rapes someone is a rapist. Rapists may use violence, drugs, or threats to get their way. People of any gender can be raped. This was not recognized by the United States law until 2011. People may stay quiet about a rape because they might feel ashamed about it.

People who cannot consent
A person may be unable to consent (say yes to) to sexual intercourse or other sexual activity. Having sex with a person who cannot consent is rape.

Children
 Children and teenagers under the age of consent are legally unable to consent. If an adult has sex with them, it is known as "child sexual abuse" or "statutory rape." In some places, teenagers who are about the same age can agree to have sex with each other. This is known as the "Romeo and Juliet" clause.

Adults who cannot consent
Some adults are unable to consent to sex.

 People who are sleeping or unconscious cannot consent to sexual intercourse.
 People who are under the influence of certain drugs such as alcohol may be unable to consent to sex. They may be unable to walk, may slur speech, or may be confused.
 People suffering from certain illnesses or disabilities are unable to consent, even though they may legally be adult. The conditions they have affect their thinking. They may not know what sex is, or they may be unable to judge the consequences of having sex. They may seem confused or unsure. Developmental disabilities, mental illness, and brain injuries can make a person unable to consent.  A court may find someone unable to consent.

Marital rape 
Marital rape is where the victim of rape is married to the person committing the rape. Unconsenting sex with a married partner is thought to be rape under the laws of some countries but not others. In the United Kingdom, marital rape was determined to be a crime in the case of R v. R (1991). Marital rape being illegal does not mean that the law is enforced. For example, in Ireland marital rape was made illegal in 1990, but by 2006 only one person had been convicted of it.

Effects of rape 
Rape is a medical emergency. People who are raped may be injured or have a sexually transmitted disease (STD). People may not know they are hurt or sick. Doctors can give medicine to treat an STD. HIV, an STD, can be prevented by early treatment. If seen quickly, a doctor can give medication called emergency contraception to prevent pregnancy. Rape is at least twice as likely to cause pregnancy as consensual sex. The reason for this is not known.

At the hospital, police can collect evidence from the victim and his/her clothing. Evidence may help find the rapist, and can help the police send him or her to jail. Waiting too long makes it hard to collect evidence. Also, taking a shower before telling the police or going to a hospital can wash off some of the DNA evidence.

Victims of rape often feel scared, sad, and/or guilty. They may think about the rape a lot, even when they do not want to. They may have nightmares about the rape. Many have post-traumatic stress disorder. People who are raped during childhood or adolescence often get borderline personality disorder. They may binge drink to cope. Talking to someone, like a counselor, can help. Rape counselors are trained to help rape victims. Sometimes doctors can give medicine to decrease fear and sadness. Calling a rape crisis center or hotline can help a victim find help.

Rape culture 
Some people believe in 'rape culture'. For example, they say that the United States has a rape culture. Rape culture is a culture that lets rape happen. It even encourages it. In the US 97% of rapists are never put in prison for their crimes. Some people are worried about women lying about being raped and men getting unfairly punished. This happens much less often than people think. In a study of college athletes, they thought that women lie about being raped 50% of the time. A 2005 study by the British Home Office found that 2.5% of rape reports were false.

Part of rape culture is victim blaming. This is when people say that someone who has been raped is the person to blame for their rape. An example of this is people saying that a rape victim was 'asking for it' because they were wearing a short skirt. It can also be more subtle. Victim blaming has been linked to the just world fallacy. This is when people think that the world is fair, so bad things only happen to people who have done something wrong. Victim-blaming is also related to 'slut-shaming'.
The idea of rape culture has been criticized. Christina Hoff Sommers argues that rape is just one type of violent crime and America's culture of violence in general is what should be fought.

Statistics 

It is not easy to find out how many people have been raped or how many people have raped. A lot of rape victims don't tell anyone that they were raped. They may be scared that they will not be believed or feel too ashamed to talk about what happened. The conviction rate for rape is very low so they might think reporting to police is a waste of time. The 2006-07 British Crime Survey found that 1 in every 200 women suffered from rape in that period. The same year 800 people were convicted of rape. This means less than 1 in every 100 reports of rape led to a conviction. A survey by Mumsnet found that 68% of women would hesitate reporting a rape to the police because of low conviction rates.
So rape report statistics are not reliable. A person may be raped but deny or not realize that what happened to them is rape, so would not say 'yes' if they were asked in survey if they had been raped. A person is more likely to say they were raped or raped someone if the word 'rape' is not used in a survey question. Different countries have different legal definitions of rape. Marital rape or rape that is not male-female is not always counted in the law or statistics.
Some studies ask what people think about rape instead of or as well of if they have raped or been raped. This comes from the idea that rape is a social problem.

United States

One in five women in the U.S. say they have been raped in their lives.  One in three Native American women has been a victim of rape or attempted rape.

The most common reason given by the rapists for raping was entitlement.

Other reasons given were that they wanted to have fun or to punish a woman. 25.3% of 511 women said they had been raped.
