Prevalence of Child Sexual

Child sexual abuse occurs frequently in Western society. The rate of prevalence can be difficult to determine.

In the UK, a 2010 study estimated prevalence at about 5% for boys and 18% for girls (not dissimilar to a 1985 study that estimated about 8% for boys and 12% for girls). More than 23,000 incidents were recorded by the UK police between 2009 and 2010. Girls were six times more likely to be assaulted than boys with 86% of attacks taking place against them. The estimates for the United States vary widely. A literature review of 23 studies found rates of 3% to 37% for males and 8% to 71% for females, which produced an average of 17% for boys and 28% for girls, while a statistical analysis based on 16 cross-sectional studies estimated the rate to be 7.2% for males and 14.5% for females. The US Department of Health and Human Services reported 83,600 substantiated reports of sexually abused children in 2005. Including incidents which were not reported would make the total number even larger. According to Emily M. Douglas and David Finkelhor, "Several national studies have found that black and white children experienced near-equal levels of sexual abuse. Other studies, however, have found that both blacks and Latinos have an increased risk for sexual victimization".

Surveys have shown that one fifth to one third of all women reported some sort of childhood sexual experience with a male adult. A 1992 survey studying father-daughter incest in Finland reported that of the 9,000 15-year old high school girls who filled out the questionnaires, of the girls living with their biological fathers, 0.2% reported father-daughter incest experiences; of the girls living with a stepfather, 3.7% reported sexual experiences with him. The reported counts included only father-daughter incest and did not include prevalence of other forms of child sexual abuse. The survey summary stated, "the feelings of the girls about their incestual experiences are overwhelmingly negative." Others argue that prevalence rates are much higher, and that many cases of child abuse are never reported. One study found that professionals failed to report approximately 40% of the child sexual abuse cases they encountered. A study by Lawson & Chaffin indicated that many children who were sexually abused were "identified solely by a physical complaint that was later diagnosed as a venereal disease...Only 43% of the children who were diagnosed with venereal disease made a verbal disclosure of sexual abuse during the initial interview." It has been found in the epidemiological literature on CSA that there is no identifiable demographic or family characteristic of a child that can be used to bar the prospect that a child has been sexually abused.

In schools
In US schools, according to the United States Department of Education, "nearly 9.6% of students are targets of educator sexual misconduct sometime during their school career." In studies of student sex abuse by male and female educators, male students were reported as targets in ranges from 23% to 44%. In U.S. school settings same-sex (female and male) sexual misconduct against students by educators "ranges from 18–28% of reported cases, depending on the study"

Underreported forms
Significant underreporting of sexual abuse of boys by both women and men is believed to occur due to sex stereotyping, social denial, the minimization of male victimization, and the relative lack of research on sexual abuse of boys. Sexual victimization of boys by their mothers or other female relatives is especially rarely researched or reported. Sexual abuse of girls by their mothers, and other related and/or unrelated adult females is beginning to be researched and reported despite the highly taboo nature of female-female child sex abuse. In studies where students are asked about sex offenses, they report higher levels of female sex offenders than found in adult reports. This underreporting has been attributed to cultural denial of female-perpetrated child sex abuse, because "males have been socialized to believe they should be flattered or appreciative of sexual interest from a female." Journalist Cathy Young writes that under-reporting is contributed to by the difficulty of people, including jurors, in seeing a male as a "true victim".
