A long term study of adults retrospectively reporting adverse childhood experiences including verbal, physical and sexual abuse, as well as other forms of childhood trauma found 25.9% adults reported verbal abuse as children, 14.8% of adults reported physical abuse, 12.2% of adults reported sexual abuse.
Data from the Centers for Disease Control and Prevention (CDC) and Behavioral Risk Factor Surveillance System corroborate these high rates.
There is a high correlation between the number of different adverse childhood experiences (A.C.E.s) and risk for poor health outcomes in adults including cancer, heart attack, mental illness, reduced longevity drug and alcohol abuse.
An anonymous self reporting survey of Washington State students finds 6–7% of 8th, 10th and 12th grade students actually attempt suicide.
Rates of depression are twice as high.
Other risk behaviors are even higher.
Some have suggested that retrospective reporting by adults of their childhood traumas is potentially biased by false memories and also by denial.
There is a relationship between child physical and sexual abuse and suicide.
For legal and cultural reasons as well as fears by children of being taken away from their parents most childhood abuse goes unreported and unsubstantiated.
David Finkelhor tracked Child Maltreatment Report (NCANDS) data from 1990 to 2010.
He states that sexual abuse had declined 62% from 1992 to 2009.
The long-term trend for physical abuse was also down by 56% since 1992.
The decline in sexual abuse adds to an already substantial positive long-term trend.
He states: "It is unfortunate that information about the trends in child maltreatment are not better publicized and more widely known.
The long-term decline in sexual and physical abuse may have important implications for public policy.
"In 2010, there were 74,100,000 US children ages 0–17.
NCANDS estimated that there were 695,000 unique children with substantiated maltreatment (78.3% were for neglect); which means that in 2010, less than 1% of the U.S. child population had a substantiated or indicated finding of any form of maltreatment.
According to the 2010 NCANDS, 17.6% of substantiated/indicated outcomes were for physical abuse (less than 0.2% of US children) and 9.2% of substantiated/indicated outcomes were for sexual abuse (less than 0.1% of US children).
Finkelhor's data from his 2010 study confirm these numbers.
According to the (American) National Committee to Prevent Child Abuse, in 1997 neglect represented 54% of confirmed cases of child abuse, physical abuse 22%, sexual abuse 8%, emotional maltreatment 4%, and other forms of maltreatment 12%.
A UNICEF report on child wellbeing stated that the United States and the United Kingdom ranked lowest among industrial nations with respect to the wellbeing of children.
In the USA, neglect is defined as the failure to meet the basic needs of children including housing, clothing, food and access to medical care.
Researchers found over 91,000 cases of neglect in one year (from October 2005 to 30 September 2006) using information from a database of cases verified by protective services agencies.
Neglect could also take the form of financial abuse by not buying the child adequate materials for survival.
The U.S. Department of Health and Human Services reports that for each year between 2000 and 2005, "female parents acting alone" were most likely to be perpetrators of child abuse.
For FFY 2011, United States reported 676,569 victims of child abuse and neglect.
Race and ethnicity of victims in 2011: 43.9% of all victims were White, 21.5% were African American, and 22.1% were Hispanic.
According to Manas Akmatov, "A median of 83, 64 and 43% of children in the African region experienced psychological, and moderate and severe physical abuse, respectively.
A considerably lower percentage of children in transitional countries experienced these forms of abuse (56, 46 and 9%, respectively)."
Females who sexually abuse children are statistically rare.
However, some of this research is based on self-report of victims.
Some studies suggest that therapy has the potential to give victims the opportunity to open up about their experience, thus making it more likely for them to admit that their perpetrator was actually a female.
So, existing research may not be a true reflection of the frequency of female sex abuse towards children.
Recidivistic female sex offenders make up such a small percentage that little is known about them as a group.

Some U.S. states have begun to address the problem of cyberbullying.
States that have passed legislation have done so generally in response to incidents within that state, to address what they believe to be shortcomings in federal laws, or to expand protection to victims above and beyond existing statutes.
There are laws that only address online harassment of children or focus on child predators as well as laws that protect adult cyberstalking victims, or victims of any age.
While some sites specialize in laws that protect victims age 18 and under, Working to Halt Online Abuse is a help resource listing current and pending cyberstalking-related United States federal and state laws.
It also lists those states that do not have laws yet and related laws from other countries. 
In recognition of the fact that the victims of sexual assault are now predominantly children and that these investigations along with child abuse and neglect cases are similar in nature, the Crimes against Children Unit was created.
