Specific diagnoses

In any given week in England [2]:

A person's diagnosis may change several times during their life. Some complex conditions are measured by how many people will be given this diagnosis over the course of their lifetime, or in any given year:

Antisocial personality disorder (ASPD): 3 in 100 people (in their lifetime)

Borderline personality disorder (BPD): 2 in 100 people (in their lifetime)

Bipolar disorder: 2 in 100 people (in their lifetime)

Psychotic disorders (including schizophrenia): fewer than 1 in 100 people (in any given year)

But estimates for these diagnoses can vary quite a lot. Also, personality disorder and schizophrenia are controversial diagnoses. These labels can be stigmatising. And many people feel that they shouldn't be used at all.
