Are there any peer-reviewed studies that show what percent of the population are believed to have Narcissistic Personality Disorder that have been published within the past ten years? I have read about studies that list the percent of people with NPD, but all of them came out on or before two thousand ten and may no longer be accurate and some of them weren't even peer-reviewed.

    $\begingroup$ Sure. I will find the others I looked at, but I linked two to the question I asked: one from 2008 and one from 2009-2010. $\endgroup$ – Tyler Mc Apr 15 at 13:33

While not a peer-reviewed study per se, but the DSM-5 says that the prevalence of Narcissistic Personality Disorder in the population is 6.2% The DSM-V was published in 2013 and is a peer-reviewed text, so it is within the 10 year criteria you mentioned and this fact is mentioned in more recent sources like an article for Psychiatric Times published in 2016. Another study from 2019 doesn't mention Narcissistic Personality Disorder, but does mention how approximately 3% of the population has Antisocial Personality Disorder, another disorder that is a common dual-diagnosis with NPD.
