1. Main facts and figures
- in 2014, there were no meaningful differences between ethnic groups in the percentage of people aged 16 and over who screened positive for a personality disorder
- although the table shows differences between ethnic groups, sample sizes were too small to draw reliable conclusions
- these figures shouldn’t be used as evidence of real differences in the population as a whole
2. Things you need to know
What the data measures
The data measures the percentage of people aged 16 and over in England who screened positive for any personality disorder.
Personality disorders are mental health conditions that affect how people manage their feelings and how they relate to other people. They include borderline personality disorder (BPD) and antisocial personality disorder.
Percentages have been rounded to 1 decimal point.
You can read more about personality disorders on the NHS website.
Not included in the data
The data does not include:
- people who live in institutional settings (such as hospitals or prisons)
- people who live in temporary housing (such as hostels or bed and breakfasts)
- homeless people
The ethnic groups used in the data
Data is shown for the following 5 ethnic groups:
- Mixed and Other ethnic groups
- White British
- White Other
This is because the number of people surveyed was too small to make reliable conclusions about all of the 18 ethnic groups used in the 2011 Census.
Read the detailed methodology document for the data on this page.
A positive screen for personality disorder indicates that someone is likely to have a personality disorder based on symptoms they have described. A full clinical assessment would be needed for diagnosis.
It is unlikely that everyone who screened positive for a personality disorder responded accurately when surveyed, particularly when interviewed. This may be because of the social stigma that some people attach to these behaviours. People were more likely to report these behaviours in the self-completion section of the survey, but not everyone completed this section.
If someone could not take part in a long interview due to a physical or mental health condition, some information about this was recorded by the interviewer on the doorstep. This information may be biased due to it having been collected from another household member.
The statistics have been age-standardised so comparisons can be made between ethnic groups as if they had the same age profile (the number of people of different ages within an ethnic group). They do not show the actual percentage of people in each ethnic group who screened positive for a personality disorder.
