How many schizotypal patients living in US?

Answer 1

The prevalence of schizotypal personality disorder is estimated to range from 0.6% to 5.1%, with a median rate of about 3% of the nonclinical population. In a clinical sample of psychiatric patients, the prevalence ranged from 2.0% to 64%, with a median prevalence of 17.5%. This wide variation in prevalence rates may reflect the controversy surrounding the classification of schizotypal disorder as a separate personality disorder, instead of a component of schizophrenia.
