Prison rape commonly refers to the rape of inmates in prison by other inmates or prison staff. In 2001, Human Rights Watch estimated that at least 4.3 million inmates had been raped while incarcerated in the United States. A United States Department of Justice report, Sexual Victimization in Prisons and Jails Reported by Inmates, states that "In 2011–12, an estimated 4.0% of state and federal prison inmates and 3.2% of jail inmates reported experiencing one or more incidents of sexual victimization by another inmate or facility staff in the past 12 months or since admission to the facility, if less than 12 months." However, advocates dispute the accuracy of the numbers, saying they seem to under-report the real numbers of sexual assaults in prison, especially among juveniles. A meta-analysis published in 2004 found a prevalence of 1.91% with a 95% confidence interval between 1.37 and 2.46%. In a survey of 1,788 male inmates in Midwestern prisons by Prison Journal, about 21% claimed they had been coerced or pressured into sexual activity during their incarceration, and 7% claimed that they had been raped in their current facility. In 2008 the Justice Department released a report that indicated that prison rape accounted for the majority of all rapes committed in the United States that year. Because of the high prison population in the United States the country has become probably the first and only in the world where rape of men is more common than of women. Statistics Research has shown that juveniles incarcerated with adults are five times more likely to report being victims of sexual assault than youth in juvenile facilities, and the suicide rate of juveniles in adult jails is 7.7 times higher than that of juvenile detention centers. In the United States, public awareness of the phenomenon of prison rape is a relatively recent development and estimates to its prevalence have varied widely for decades. In 1974 Carl Weiss and David James Friar wrote that 46 million Americans would one day be incarcerated; of that number, they claimed, 10 million would be raped. A 1992 estimate from the Federal Bureau of Prisons conjectured that between 9 and 20 percent of inmates had been sexually assaulted. Studies in 1982 and 1996 both concluded that the rate was somewhere between 12 and 14 percent; the 1996 study, by Cindy Struckman-Johnson, concluded that 18 percent of assaults were carried out by
