What to know

People with a PTSD claim and none in the previous 360 days, rising across the years. It counts who reached care with a PTSD diagnosis, far fewer than develop PTSD in population surveys, so it is a floor for diagnoses, not for onset; a Danish registry study found a similar diagnosed rate in adults. No worldwide PTSD incidence exists: GBD does not model PTSD separately.

Arithmetic

4.2 to 8.3 per 100,000 / 10 = 0.42 to 0.83 per 10,000 per year.
