A number of studies have been conducted in recent years to determine the prevalence of personality disorders in the general US population.
According to a 2007 study, 9.1% of the US population (about 1 in 11 people) meet the DSM-IV criteria for a personality disorder. Two previous smaller surveys have estimated the percentage between 9.0% and 15.7%.
The following table shows statistically how likely it is that a person who is diagnosed with one personality disorder will also be diagnosed with another personality disorder, as defined by the American Psychiatric Association's Diagnostic & Statistical Manual of Mental Disorders (DSM-IV).
The numbers displayed in the table below are a statistical measures of co-occurrence known as "tetrachoric correlations". The more positive the number, the more likely it is that a person will be diagnosed with the second personality disorder listed. The more negative the number, the less likely it is that a person will be diagnosed with the second personality disorder in the table.
Note: This data was compiled from an initial survey of 5692 people in the US. None of the people in the survey sample were identified as meeting the criteria for Histrionic Persoanlity Disorder or Narcissistic Personality Disorder, and no comorbidity information is therefore given for HPD or NPD.
Comorbidity Between Personality Disorders and DSM-IV Axis I Disorders
67% of people who meet the DSM-IV criteria for a Personality DIsorder have been found in a 2007 study to also meet the criteria for at least one of the DSM-IV Axis I disorder. The table below shows the probability that a peson who has been diagnosed with a personality disorder will also meet the criteria for each of the following Axis I disorders, as defined by the American Psychiatric Association's Diagnostic & Statistical Manual of Mental Disorders (DSM-IV):
Note that although 67% of the people meeting the criteria for an Axis II - or personality disorder also meet the criteria for an Axis I disorder, the reverse is not true. Only 24.8% of people meeting the criteria for an Axis I disorder also meet the criteria for an Axis II disorder.
UK 2006-2007 Personality Disorder Hospital Admissions
The chart below gives UK National Health Service 2006-2007 Breakdown of Personality Disorder Diagnoses per hospital admission. Diagnoses are based on the World Health Organization (WHO) system for classifying physical and mental disorders International Classification of Diseases (ICD-10).
It can be seen from the chart that 2/3 of all hospital admitted personality disorder diagnoses in the UK are for Emotionally Unstable Personality Disorder (EUPD) - which is known internationally as Borderline Personality Disorder (BPD).
UK 2006-2007 Personality Disorder Hospital Admissions by Gender
The chart below gives UK National Health Service 2006-2007 Breakdown of Personality Disorder Diagnoses by gender per hospital admission. Diagnoses are based on the World Health Organization (WHO) International Classification of Diseases (ICD-10).
The data shows that about 65% of in-patient personality disorder cases in the UK are diagnosed in females and 35% in males. BPD and HPD are significantly more common among females and APD, SPD and OCPD are significantly more common among males.
Self Harm Statistics
British Medical Journal 2002 Study on Self Harm in Adolescents
A 2002 survey of 15 and 16 year old students in 41 schools in England found that 6.9% reported acts of deliberate self-harm in the previous year, with a significantly higher prevalence in females (11.2%) than in males (3.2%)
In 2004, suicide was the 11th leading cause of death in the US. There were 32,439 recorded suicides, or 109 suicides for every million people (0.01% of the population). It is estimated that about 25 suicides are attempted for every death recorded.
Gender Distribution:
Women report 3 times as many suicide attempts as men. However, men account for the majority (79.4%) of actual suicide deaths.
In the US, an estimated 903,000 children (1.2% of all children) were victims of abuse and neglect in 2001.
57.2 percent of victims suffered neglect (including medical neglect),
18.6 percent were physically abused
9.6 percent were sexually abused;
26.6 percent of victims were associated with additional types of maltreatment.
Percentages of victims are similar for males and females (48.0% and 51.5% respectively).
Children in the age group of birth to 3 years account for 27.7% of victims. Victimization percentages decline as age increases.
In the US, more than half of all child abuse victims are White (50.2%); one-quarter (25.0%) are African American; and one-sixth (14.5%) are Hispanic. American Indians and Alaska Natives account for 2% of victims, and Asian-Pacific Islanders accounted for 1.3% of victims.
19% of reported and substantiated child abuse cases result in the child being removed from the home.
The answer may surprise you. It is most comonly not the proverbial "stranger" that most children are warned to avoid - it is more likely to be someone much closer to home:
Divorce figures exclude data for California, Georgia, Hawaii, Indiana, Louisiana, and Minnesota. Populations for divorce rates also exclude these states.
US Child Custody Statistics
Many people believe that mothers are naturally better caregivers than fathers. And the US courts seem to agree. US Divorce Statistics show that a divorcing mother is 7 times more likely to retain sole custody of her children than a father:
