Worldwide pooled [[prevalence]] of [[personality disorder]] as found by [[meta-analysis]] of studies conducted from 21 countries is 7.8%.

OCD is twice common in females than males and 75% of individuals diagnosed with BPD are females. No sex predilection is found with rest. [[Narcissist PD]] is found in 20% of military personals, 17% first-year medical students and 6% [[forensic]] population.
 
==Epidemiology and Demographics==
===Prevalence===
 
The [[prevalence]] of personality disorder in the general community was largely unknown until surveys starting from the 1990s. In 2008 the [[median]] rate of diagnosable PD was estimated at 10.6%, based on six major studies across three nations. This rate of around one in ten, especially as associated with high use of services, is described as a major [[public health]] concern requiring attention by researchers and [[clinicians]].<ref>{{cite journal|last=Lenzenweger|first=Mark F.|title=Epidemiology of Personality Disorders|journal=Psychiatric Clinics of North America|year=2008|volume=31|issue=3|pages=395–403|doi=10.1016/j.psc.2008.03.003|pmid=18638642}}</ref>. According to the [[National Co-morbidity Study Replication]] (NCS-R), the [[prevalence]] of personality disorders in 18 years and older in the last year was 9.1%. It was a nationally conducted household survey between 2001-2003. <ref name="urlNIMH » Personality Disorders">{{cite web |url=https://www.nimh.nih.gov/health/statistics/personality-disorders |title=NIMH » Personality Disorders |format= |work= |accessdate=}}</ref>.
 
The [[prevalence]] of individual [[personality disorders]] ranges from about 2% to 3% for the more common varieties, such as [[Schizotypal personality disorder|schizotypal]], [[Antisocial personality disorder|antisocial]], [[Borderline personality disorder|borderline]], and [[Histrionic personality disorder|histrionic]], to 0.5–1% for the least common, such as [[Narcissistic personality disorder|narcissistic]] and [[Avoidant personality disorder|avoidant]].
 
A screening survey across 13 countries by the [[World Health Organization]] using [[DSM-IV]] criteria, reported in 2009 a prevalence estimate of around 6% for [[personality disorders]]. The rate sometimes varied with [[demographic]] and [[socioeconomic]] factors, and functional impairment was partly explained by co-occurring [[mental disorders]].<ref>{{cite journal|last=Huang|first=Y.|coauthors=Kotov, R., de Girolamo, G., Preti, A., Angermeyer, M., Benjet, C., Demyttenaere, K., de Graaf, R., Gureje, O., Karam, A.

According to the [[National Epidemiologic Survey on Alcohol and Related Conditions]] (NESARC), the most common PD in US is [[Obsessive-compulsive disorder|Obsessive-compulsive]] PD which is 7.9% followed by [[Narcissistic personality disorder|narcissistic]] 6.2% and boderline PD 5.9%. <ref name="pmid21637629">{{cite journal| author=Sansone RA, Sansone LA| title=Personality disorders: a nation-based perspective on prevalence. | journal=Innov Clin Neurosci | year= 2011 | volume= 8 | issue= 4 | pages= 13-8 | pmid=21637629 | doi= | pmc=3105841 | url=https://www.ncbi.nlm.nih.gov/entrez/eutils/elink.fcgi?dbfrom=pubmed&tool=sumsearch.org/cite&retmode=ref&cmd=prlinks&id=21637629  }} </ref>

Overview

Worldwide pooled prevalence of personality disorder as found by meta-analysis of studies conducted from 21 countries is 7.8%. Global rates of cluster-A PD is 3.8%, cluster-B is 2.8% and cluster-C PD is 5% [1]. In United States (US), it is around 10%, with major disease burden contributed by obsessive-compulsive PD followed by narcissist and borderline PD. In the rest of countries, it varies [2]. OCD is twice common in females than males and 75% of individuals diagnosed with BPD are females. No sex predilection is found with rest. Narcissist PD is found in 20% of military personals, 17% first-year medical students and 6% forensic population.

Epidemiology and Demographics

Prevalence

The prevalence of personality disorder in the general community was largely unknown until surveys starting from the 1990s. In 2008 the median rate of diagnosable PD was estimated at 10.6%, based on six major studies across three nations. This rate of around one in ten, especially as associated with high use of services, is described as a major public health concern requiring attention by researchers and clinicians.[3]. According to the National Co-morbidity Study Replication (NCS-R), the prevalence of personality disorders in 18 years and older in the last year was 9.1%. It was a nationally conducted household survey between 2001-2003. [4].

The prevalence of individual personality disorders ranges from about 2% to 3% for the more common varieties, such as schizotypal, antisocial, borderline, and histrionic, to 0.5–1% for the least common, such as narcissistic and avoidant.

A screening survey across 13 countries by the World Health Organization using DSM-IV criteria, reported in 2009 a prevalence estimate of around 6% for personality disorders. The rate sometimes varied with demographic and socioeconomic factors, and functional impairment was partly explained by co-occurring mental disorders.[5] In the US, screening data from the National Comorbidity Survey Replication between 2001 and 2003, combined with interviews of a subset of respondents, indicated a population prevalence of around 9% for personality disorders in total. Functional disability associated with the diagnoses appeared to be largely due to co-occurring mental disorders (Axis I in the DSM).[6]. According to the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), the most common PD in US is Obsessive-compulsive PD which is 7.9% followed by narcissistic 6.2% and boderline PD 5.9%. [2]

A meta-analysis conducted to calculate global prevalence of personality disorders in 2020 by Winsper et al. revealed the worldwide pooled prevalence to be around 7.8%. [1].

The studies regarding epidemiology of individual types of PDs are lacking. According to National Institute of Health (NIH), the point prevalence of BPD is 1.6% and lifetime prevalence is 5.9%. [7] The data by NESARC revealed no difference in gender for prevalence of BPD. The prevalence of paranoid in US ranges between 2.3-4.4% and more common in males. [8] The 2004-2005 Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions demonstrated that the prevalence of schizotypal PD to be around 3.9% with greater rate in males as compared to females. [9]. For Narcissistic PD, the prevalence was found to be 6.2% in US people aged 18 years and above with higher rates for male population. [10].

The prevalence of PDs according to NCS and NESARC are summarised as follows: [11]

Prevalence of personality disorders
Type of personality disorder NCS NESARC
Paranoid personality disorder - 1.9
Schizoid personality disorder - 0.6
Schizotypal personality disorder - 0.6
Antisocial personality disorder 0.6 3.8
Borderline personality disorder 1.4 2.7
Histrionic personality disorder - 0.3
Narcissistic personality disorder - 1.0
Avoidant personality disorder - 1.2
Dependent personality disorder - 0.3
Obsessive–compulsive personality disorder - 1.9


There are also some gender differences in the frequency of personality disorders. They are shown in the table below.
